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.
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. www.nichia.co.jp/specification/products/ld/NDE4116-E.pdf
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?
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.
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!

Hi,
After a year of being on CPF, I am now trying to clean up my loadout and hopefully get back into lasers with a few flashlights I can keep.
I bought it here. M2Xvn
So first up I'm selling the M2Xvn flashlight. It has
The XPG2 PDTc led which paired with the Olight M2X reflector can produce up to 385,000 lux, equals to ~1200+ meters!! It has a lumen rating of 900 at turn on.
15$ extra option added, copper sink, polished, and spring mod.
10$ extra option added, Single mode only
5$ extra option added, V54 engraving
Has a duty cycle of 7mins on and 1 min off.
I'm selling this one first for $80 w/batteries and accessories when I bought it at $175 w/ everything
Only used for ~ 30 mins.
Comes with:
Flashlight Case
M2Xvn
Holster
Lanyard
18650 Sony VTC Battery
V54 Certification
Extra O-Rings
Original Manual
Would Be a good starting point for a powerful hand-held? Using the unit to drive the diodes directly? The VR is stout, with one limitation-.2 ohms is the resistance limit. Yet voltage/wattage are user-settable from 0-9v and 0-250 watts. Made to house a trio of 18650's. The 510 connector is pretty standard, the duty cycle at .2 ohm output is continuous.... it exceeds the power requirements I do believe, yet that is adjustable. Several of the heads have set-screw power connectorsthat would direct-wire a diode pair......any input?
Hi,I'm quite new to lasers and need some answers..
I ordered red 200mW laser because i like burning more than attracting people with green laser.At first it looked simple but now it doesn't.
I know that goggles are necessary for lasers above 5mW but what i quite don't understand is that they cost more than laser itself.This red laser i ordered costs 49Eur and most of goggles i've found cost about the same as laser or even more.I can trust Dragon Lasers, goggles cost 24$ 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.
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.
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?
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!
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.
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

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
