WTB: 671nm portable

Hello folks!

In my pursuit of DPSS wavelengths, I've now come across 671nm as the next color in my sights. I've messaged Lasever and been quoted the following prices for a 671nm cylindrical module:
100mW - $350
200mW - $400
300mW - $480

However, I'd prefer to purchase a 671nm portable from a forum member, simply because of the lower cost and the ease of making the purchase.

So if anyone here has a 671nm and would like to get rid of it, please send me a PM.

Thanks!

Need source for 425nm diode.

I am wondering if anyone has a source of single "low" priced N!CH!A NDV4A16E diodes.
I want to do a pen build with one sometime this year after I acquire my tax return laser but can't find any of these diodes anywhere or any information beyond the datasheet for them.

I vaguely recall seeing someone with a 425nm build in their sig but am unsure who's it was.
If that person or anyone else knows where the diode was acquired and even better yet at what price I would greatly appreciate this information.

Datasheet here:www.nichia.co.jp/specification/products/ld/NDV4A16E-E.pdf
I came across this browsing through N!CH!A's selection of diode in the visible spectrum hoping to find something truly unique but have yet to find a source.



EDIT:
I would also be interested in a reasonable source for N!CH!A NDE4116 diodes as this is another wavelength range I have a particular interest in as I can perceive very small changes in the green spectrum and this should fall right at the blue end of green.

200mW laser: Vice needed?/soldering

Hey I am new to lasers and I just got all parts to build a 200mW blu-ray (Diode, Driver, Aixiz module).
I've been inspired by StyroPyro's tutorial and I've got some questions.

1. Do I need to use a vice to put the diode into the Aixiz module or are there other ways to do so!

2. Is that weird soldering trick necessary? Can I just solder the two pins separately and let the case pin there?

Thanks, every support is appreciated :)

I have a question about dtr module and survival laser.

Hello,
I will buy PL520 50mW module that is soldered driver at DTR shop, and Bargain No diode host bundle in Survival Laser.

Now, Just wondering the module will fit that host?
even driver soldered in module?

And if it will be fine, What should i select driver current option? just blank battery contact board?

If it cannot fit, i will make Laser with PL520, Atoids tin, and etc. Should i put heatsink into there?

Sorry for my bad english and thanks to read. :)

Weapon to reach out of atmosphere?

I just want people's opinion on what type of weapon this might be?
This is above earth btw. What would you need to go out of the atmosphere like that? Definitely not a laser since it looks like a "missile" projectile type shot.
Plasma?



It starts at :15 seconds, upper left. The "projectile" can be seen at :18-19 . Nice dodge by whatever they were firing at.

Hello

Just saying hello to everyone, I've never done a laser at all, but extremely interested. Spent some years as a machinist and mechanic, currently beat nails to get by. I'm really wanting to do a diy soon may have a few good ideas, hope you guys can help develop me!

bao cao su có gân sung sướng hiện giờ thoải mái

Bao cao su lÃ* "kẻ địch" cá»§a Công giáo

Không giống như gần như các tôn giáo khác trên quả đât, Công giáo cấm mọi hÃ*nh vi kiểm soát sinh nở như nạo phá thai, uống thuốc tránh thai vÃ* tháº*m chÃ* lÃ* cả dùng o dau ban bao cao su co gan.

Ireland, một đất nước theo Công giáo, từng cấm nháº*p khẩu vÃ* bán bao cao su cho tới táº*n năm 1979. Năm 1985, chÃ*nh phá»§ Ireland quyết định dỡ bỏ lệnh cấm nÃ*y vÃ* bị phÃ*a nhÃ* thờ buộc tội "sẽ mở đầu cho một cuộc suy thoái trượt dÃ*i về mặt đạo đức".

Bill Gates cũng bán bao cao su

Tá»· phú Bill Gates vÃ*o năm 2013 từng tuyên bố ông đã đầu tư 100.000USD vÃ*o một dá»± án khởi nghiệp nhằm phát triển một loại bao cao su "siêu mỏng, siêu an toÃ*n" mÃ* vẫn đảm bảo đôi uyên ương "vui mắt" trong mỗi lần quan hệ.

Hai loại bao cao su tương tá»± ý nghÄ© đó cá»§a Bill Gates đã được sáng chế ra. Tại Anh, các nhÃ* kỹ thuáº*t tại Đại học Manchester sáng chế ra một loại bao cao su "siêu mỏng, siêu bền" từ graphene, một loại tinh thể carbon. Tại Mỹ, Đại học Oregon cho ra mắt loại bao cao su lÃ*m bằng chất liệu polyurethalene có độ dÃ*y chỉ bằng một ná»*a so với bao cao su thông thường.

Mang bao cao su lÃ* vi bất hợp pháp luáº*t

Không chỉ có riêng Ireland từng cấm bao cao su. Tại Mỹ, năm 1873 chÃ*nh quyền liên bang duyệt y Đạo luáº*t Comstock, theo đó cấm phát triển mọi loại váº*t phẩm có liên quan đến tình dục bao gồm sách báo đồi truỵ, đồ chÆ¡i tình dục vÃ* cả bao cao su. Điều nÃ*y dẫn tới hệ quả trong Thế chiến đầu tiên, binh lÃ*nh Mỹ lÃ* những người duy nhất trong khối Hiệp ước không có bao cao su, khiến cho hÃ*ng ngÃ*n binh lÃ*nh bị lây bệnh láº*u vÃ* giang mai.

Đạo luáº*t Comstock đã dỡ bỏ từ lâu, vÃ* người Mỹ bây chừ có thể thoải mái mua bao cao su mọi lúc mọi nÆ¡i. Tuy nhiên, việc mang bao cao su trong người có thể lÃ* bằng chứng buộc tội một thiếu nữ lÃ* gái mại dâm trước toÃ*. Để tránh rá»§i ro, gái mại dâm "xịn" thường không mang theo bao cao su, khiến cho tá»· trọng bệnh truyền nhiễm qua đường tình dục tăng lên.

A few newbie questions.

Some input would be greatly appreciated. I am wondering if something like this(see link below)
Wismec Reuleaux RX200 Jaybo Designs Triple 18650 Mod

Would Be a good starting point for a powerful hand-held? Using the unit to drive the diodes directly? The VR is stout, with one limitation-.2 ohms is the resistance limit. Yet voltage/wattage are user-settable from 0-9v and 0-250 watts. Made to house a trio of 18650's. The 510 connector is pretty standard, the duty cycle at .2 ohm output is continuous.... it exceeds the power requirements I do believe, yet that is adjustable. Several of the heads have set-screw power connectorsthat would direct-wire a diode pair......any input?

Safety goggles

Hi,I'm quite new to lasers and need some answers..
I ordered red 200mW laser because i like burning more than attracting people with green laser.At first it looked simple but now it doesn't.
I know that goggles are necessary for lasers above 5mW but what i quite don't understand is that they cost more than laser itself.This red laser i ordered costs 49Eur and most of goggles i've found cost about the same as laser or even more.I can trust Dragon Lasers, goggles cost 24$ there but i'm from Europe so shipping costs another 18$..I also need to know more about goggles.
Questions:
1.Where could I buy good Safety Goggles for red laser 200mW 650nm in Europe that cost less than laser itself.
2.Can i even see the bean through goggles?It would be useless to have goggles if i can't see anything.
3.Is it safe to look at the bean if i'm pointing to the wall? (no reflective objects).
4.Does Ebay or Amazon have any good goggles?If yes,show some.
I've looked through forums but many threads are old or not exactly what i'm looking for.

1 watt laser, ADVICE ASAP! (Eye damage?)

Hello Guys,

I have a pair of Eagle protective goggles for 445 nm and a 1 Watt blue laser.
Was testing it in the kitchen, pointing at a white wall, wearing a white t-shirt.

(SEE IMAGE) Imgur: The most awesome images on the Internet
NOT ME ON THE PICTURE!
My nose is kind of big lol, so the "gap" between my cheeks and my glasses are quite big, maybe 0.5 cm instead of a milimeter.

So when I use the laser I can see the room & my t-shirt turning blue in my pheripeal vision, but it's not so bright that I need to blink by reflex or anything. It's more like I could "sense" the room becoming blue.

My question is: Is this light dangerous for my eyes?
I can't be the first one this "happens" to.

Quick Question on Spring Modules

This morning I was doing my daily eBay browsing and found a 250mw red module for just $7! I'm not really crazy about building lasers, but I thought it would be cool to put one of these modules into a pen host. I just wasn't sure how to accomplish this because I'm only used to spring modules in the pen hosts. This might be a stupid question, but how do springs translate into leads? Here are the things I was looking at:
w/ Battery Case Focusable Laser Module 250mW High-power New Red Beam
And
Laser Pointer Penstyle Host | eBay
Are there any other incompatibilities I'm missing?

Fs: Lots of stuff! (Added a Laser 1-2-17)

Had this for almost a couple months now and I have something a little more beefy on the way so this one needs to go.

Kale cnc lasers

Hey has anyone used or heard of kale CNC lasers? They make industrial lasers such as 1w 445nm modules, like the one I bought recently, I was just wondering if they are a good company or did I make a bad decision. Thank you!

eBay Driver to avoid (imo)

I know the saying "you get what you pay for" but I'm a frugal slow learner. I bought a couple of these cheap eBay drivers with the intent of running 2 diodes off one at about 5 volts. The description was pretty vague, but they were cheap so I scooped them. Well, I led'd 2 of my good diodes double quick because the 1/2 turn pot goes from zero to god damnit in half a finger twitch. Also at 4 volts the driver got too hot to touch but running 2 of my cheap 5mw drivers at 5 volts and cranked all the way it ran cool and didn't cook even one of them by itself... 😠 I should have run a test load on it, but I doubt it would have helped much considering its odd behavior with the lesser diodes. Anyways, if I did something wrong or if these drivers are indeed crap I'll figure something out. Any ideas from the pros? Im seriously thinking about just getting a prefab 500mw or 1 watt unit in 808 for the engraver and buy a better driver for my red from a better source. I guess it also doesn't help much that I'm kinda n00bish to the electronics game. I do have basic knowledge from an extensive background in automotive and tinkering with various things but this micro stuff hurts my aging eyes.

some new pics 1/3/17

These pics were taken about a month ago. I started with lasers and my 8" glass sphere and switched that out for a 4" pyramid and a Phillips Hue Go lamp. On these shots the lasers were pointed downward into mirrors with a few having a laser go behind the glass sphere to get the effect I was trying to get. There are also a few nice shots where I laid the camera (with my 8mm fisheye) flat on the table looking up. And there is also a shot of my laser room showing my newly painted black floor. This is a part one from the photo shoot. Maybe one day I will post part 2 which is using two glass pyramids and the Hue lamp w/lasers. Enjoy

Survival Laser Open Thread

Hi Fellow LPF Members,

My name is Gary Rosenfield, and my wife Lorraine and I own and operate Survival Laser, Inc., a Utah, USA-based company selling electronic components, host hardware, flashlights, optics, safety products, batteries, tools and accessories to the laser hobbyist community since 2010.

You may have noticed that we now have a banner ad on LPF. We want to increase promotion of our stores with advertising and additional forum participation when possible. I also run a business called RCS Rocket Motor Components, Inc. which takes up much of my time (RCS sells rocket-related products to hobby, commercial and educational customers under the AeroTech, Quest and other brand names). The purpose of this thread is to more actively engage with members and customers to obtain your feedback (good and bad), publish company news and solicit ideas for new and improved products and services.

A few things up front. I have been interested in lasers since I was around 10 years old. I built an argon gas laser when I was in high school and it won second place in the Orange County, CA science fair. Around the same time I was involved in the rocketry hobby and also had an interest in solar power. My attention to lasers waned and rocketry became my primary interest and eventual avocation until I saw an ad for the Wicked Lasers Arctic laser in mid-2010. It was at that time I told my wife that "I think I've found a new hobby!" :whistle:

I noticed right away that it was relatively difficult for me to find products in a straightforward manner, and I felt that the hobby could use a more business-oriented approach that we had developed with the rocket companies.

Next, we had to divide the business into two separate webstores several years ago because of FDA concerns; survivallaser.com is the store for our international customers, while survivallaserusa.com is the store for our U.S. customers. The U.S. product line is more restrictive and vague on the exact application of the items. I cannot elaborate much more than that. We have found that this arrangement has worked well for us since its implementation.

Finally, we ran out of our popular stainless steel hosts last year but they are now back in stock. I plan to modify the multiple product pages to a single page offering the host with and without heat sinks and various marking and other options to make the buying process easier.

A couple of notes before we start:
- I do not know everything about the hobby, but I learn more every day
- My strengths are currently geared more towards the business side of the hobby
- I will be professional, please return the respect

With that, I await your comments. :beer:

Cryonics 2201-15sl argon laser system

Are these lasers any good I can pick one up for around 100 dollars without a power supply, is there anything I need to know about them?
