Can this laser use new style HeNe tubes? Or can its original tube not be replaced I just bought this laser for 40 dollars that still works I'm just wondering if it was worth the money thanks!

Laser in mirror burned it's own diode out?
So I was playing with my great little 300mw red laser off ebay. Of course then I had to point it in a mirror and try to align the beams. The moment I did the diode went down to a faint glow.
Did I kill it?

WTB: 1122/1123, 1319, 1342 nm YAG Line & OC mirrors to produce yellow...
I've been looking on ebay as well as at some of the supplier web sites for mirrors which can be used with ND:YAG's for 1122/1123, 1319/1320 or 1342nm for use with a crystal to produce one of the yellow wavelengths, but cannot find them either used or new. If anyone comes across them, or a listing for them on a web site, please let me know.
If you see this post a few months from now please post any additional information you might have anyway. Often, I get kind responses to my WTB posts, go look and then don't see exactly what I need. If I have not replied I have found what I need, I'm still looking and could use your help. I would be interested in a non-functioning cavity with these mirrors if I can use the parts out of it. If you post and it is exactly what I need and able to order and receive it, I will donate an additional 20 bucks to the forum, or send the money to you, which ever. I've already spent a lot of time searching, not finding them yet.
Edit: I did find and buy some 1122nm OC mirrors for an inter-cavity LBO crystal to produce 561nm on ebay, but not the mirror for the back side reflector in a ND:YAG cavity, so interested in other manufactures mirrors too. I am making the assumption the back side mirror should be a line mirror, or selective for those wavelengths, maybe that isn't true for the back mirror?

What just happened?
Every so often I look up various things on Googe Trends to see how relevant certain subject matters are just for the luls. For no reason, tonight I decided to look up "laserpointerforums":

What.
Why is there a massive spike for Jan 2017? What has recently happened that would create a surge like this?
The only thing I can think of is this video:
Note that while the title of the video is "5 EXPERIMENTS WITH LASERS THAT WILL BLOW YOUR MIND !!", it doesn't really contain any experiments or mind-blowing material, but it DOES have over 10 million views.
The only problem is that it was created last month, and the spike is for this month.
So... what just happened?

What's a high amount of hours for an argon laser?
Hello I was just wondering what a high amount of hours is for an argon ion laser. And also what would be a good range of hours, ive been looking at some on eBay made in 1991 and they look pretty new, but I'm asking because I don't want to buy one then it quit working a few months later. Thanks.

Good external drive for backups, but rarely used.
I'm looking to buy an external (usb) drive to store some backups once in a while, but actually use rarely (perhaps weekly to monthly to store a backup, hopefully never or only once to recover one).
I only need it for fairly critical data so it need not be very large (100 GB woud suffice, 200 would be nice).
What do you guys think would be a good choice here? I could get a standard 2.5" harddisk in an enclosure with plenty of space quite cheaply. I could also get a 128 Gb SSD external drive for a reasonable but higher price.
I wonder if the SSD would be more reliable if i left it unused for a long period of time. I've had 2.5" spinning external drives give me problems in the past: At times i left them for a few months after which i tried to access them again and they no longer worked. Mostly this came up when i wanted to create and additional backup, not recover, so it has not caused major problems but still is a bad thing.
I do have multiple online backup solutions so it's not mission critical that this works 100% of the time, but i wonder what would fare better over a period of several years with irregular use: ssd or hdd.
Also i want to store the data on these drives in truecrypt containers/partitions so that there is no problem if they are even stolen or lost. I'm not sure to what degree that factors in to things, but perhaps it's important.

Custom,corrected,NUBM08,Blackbuck,Adjustable,6w
My first 6x corrected build, decided to use the NUBMO8 diode and since I'm using the blackbuck M8 again and it's going to be adjustable I decided to set the
Driver at 5a, This build is one of a kind Most corrected builds are huge and
Use beam expanders, I wanted this build to burn at long distance, be very
Powerfull, adjustable and as small as possible.
Using Jordan's 20mm module with a flattened out bed for the driver was the only
Way I was going to get all the comments into the head,
Honestly the pot is touching the side of the driver, the switch is touching the pot
And the battery positive pill is touching the switch, this is how tight the components are but all wiring is very well insulated.
My design of having 2 pieces press together for a host is unique and works well,
Battery compartment one piece and head with all components the other, also instead of using 2 18650 I decided on using 2 18500 just to get the second part of the host a little shorter.
I'm using blue laminate inside the acrilic tube to reduce the brightness coming from the optical compartment, these reflections can be hasardess, this beam is so bright and hot it's very difficult to get decent pictures, I can feal the heat coming off the beam a few inches away with my hand, I also lit a cigarette 5m
Away in just a few seconds.
I'm very happy I used this diode it's so beautifully bright and with the adjustable pot turned to max witch is 5amps. I'm getting over 6w awesome,
Also that UV glue is so tough and used in small amounts you can't even notice it and the optics won't be moving any time soon.

This forum could use a Jury system
As I'm sure we all know, the spam and troll posts have become quite numerous lately. It's not fair to expect the mods to ALWAYS be on to deal with it, so what if regular members were given some tools to address the issue? Another forum I go to uses a jury style system where if a post is reported it goes to a bunch of currently active forum members who basically vote guilty/not guilty on the post. If a post receives a certain amount of 'guilty' votes then it's automatically deleted without the need for mod intervention.
Another option would be something like requiring a small 25 cent donation to post on the forum. It would be low enough that any normal person could pay it, but it would probably keep people away if they just wanna sign up to post spam garbage or troll. Getting tired of the daily "Hi everybody, read this guide on how to give a good blow job" threads.

Anyone know about these lasers? How to set them up?
Hello can anyone tell me about this laser I found on eBay, I want to buy it but I don't know if I need a special power supply or what exactly do I need to run it? Does it look like a normal red laser when on? Except for the fiber cable it runs through.

The ProtoBoost V1
So...
I may or may not have a driver currently in the works.
It is my understanding that there is a severe lack of readily available drivers on the market right now, and as such I'm attempting to step up to the plate to, hopefully, fill that void.
Now. The ProtoBoost.
This is not going to be a small driver; small means hard to heatsink, and with the potential current capabilities of this sucker, you definitely want it to be easy to heatsink.
It's clockin' in currently at 11.78 mm by 22.30 mm. A little larger than most drivers, but hey, here's the best part;
All of the parts that need heatsinking, are all on one side. Makes it EXTREMELY easy to remove heat from this thing.
And the MOSFET? Utilizes a new package that has an exposed metal part on the top of it. The mosfet also has ridiculously low RDSon, we're talking bout 5 milliohms for the voltage that it'd be driven with.
The diode? Uses an extremely efficient schottky with a voltage drop of 0.39 volts at 3 amps. At 5 amps, even lower.
It'll also use a potentiometer, but this is OPTIONAL. The board has a spot for a resistor as well, if potentiometers aren't your thing.
I'm also using 2 oz copper boards, with much thinner substrate (0.8 mm vs 1.6 mm like boards of old) thanks to OSHpark.
I'm attempting to make 5 amps the target current output for this driver. It SHOULD be capable of more, but I do not have the boards in hand currently. It'll also be able to run off of two AA batteries as well, though with diminished current capability.
I'm expecting to get the boards back in a few weeks. I'll keep this thread updated with necessary information and pictures as they come.
I really hope you guys are excited for this!! Lord knows I am. :yh:
Here's some EAGLE pictures for you all to enjoy. <3

Back to gas
My first laser was a HeNe from Meredith back in the early 90s. I will always miss that laser,(stolen in a break in). Now I have a nice little HeNe.
It's a Melles Griot P-50 and I have the bug again.

This is how I got it.

And one of it running.
Puts out 1mw at 632.8nm
So I have the gas bug again and I'm already looking for my next one.

Suggestion for Bench Top Supply
I know that there have been postings on this subject. I am looking for some current information (no pun intended.) I am looking for a reasonably priced bench supply...at least 10 A if not more. I do not plan on using it all the time so something reasonably priced would be nice. Anway suggestions?

Ces 2017!
Today is the official day 1 of CES, and we've already seen some cool tech.
CES is always an interesting event to follow for me since we see a lot of different paths technology can take in the coming years. Not everything seen there even makes it into consumer popularity.
I was actually supposed to be there this week, but I ended up unable to go. Oh well, it's well-publicized.
The big highlights so far are a lot of automotive technologies, but there should be a lot more in the days to come.
Anyway, anything you're looking forward to in CES? Favorite tech categories to follow? Heard of anything good from the showroom?

I need help with finding a power supply for this laser ASAP
Hello guys, I was just wondering how might I go about finding a power supply for this laser I just bought because I'm pretty sure I need like a DC power supply that plugs into the controller board only problem is that the part where you plug in the DC adapter looks kind of like a VGA cable port from a computer so I'm super confused thank for the help!

M140 and general wiring advice
Hello everyone! It's been a really long time since my last post! The last time must have been years ago. So back then I was ready to get into lasers but some things came up and I got rather side tracked. Now I'm back and ready to learn more. I remember having built a 445nm after some careful reviewing of diagrams provided by Eudaimonium but now I'm not quite sure I remember. However, I have with me a Survival Laser S4 Host with a drilled pill, a blank battery contact board, and an M140 pre soldered to an X-Drive by DTR. Now I am aware that the S4 is a small host, so that I should have a VERY short duty cycle. The only thing is that I've forgotten about wiring and the significance of the case pin. It would seem that wiring changes depending on if the setup is case negative or case positive. I'm not really sure how I should go about wiring the driver to the contact board, but I'm guessing it goes kind of like this:
The flat, negative end of the batteries face the spring side/tail cap and their convex, positive ends face the contact board. Then I just wire the positive on the contact board to the positive on the X-Drive and do the same with the negatives? It's just been a while.
