I forgot, our anniversary isn't until January 4th, so its plenty of time.

My wife bought me a lasense model from someone on here last year for anniversary. It is a 575 Yellow and works beautiful This year I was hoping to have it made into a handheld. It that something you could do for me? I'm NOT looking for delicate, rather something that will handle a 18650 or...

Bought my 575nm from Lifetime. It is actually very Lemony yellow not green like the 560nm versions. it is sensitive to heat, if I run it more than 15 minutes it can get a little flakey. otherwise its rock solid. Ive had it about a year. Impossible to find the 575nm wavelength anymore, AFAIK.

usually a desk mic stand with clip works well depending on size...

came up today, big HeNe lasers https://www.ebay.com/itm/265970439802?mkevt=1&mkpid=0&emsid=e11021.m43.l1120&mkcid=7&ch=osgood&euid=4188ab3491d542d28a5ebaa6ec3729c9&bu=43203163230&ut=RU&exe=0&ext=0&osub=-1%7E1&crd=20221104015029&segname=11021

I am going to repeat what was stated above - come back when you are 18 and we will offer suggestions. Otherwise, no one on here should be offering any. If you are still interested then, ask and I'd be happy to help

I've built a few of these lately with some left over drivers I had. Pics are helpful BTW. No one answered, so I will - there is no "Warm Up" on these. Also, you are not pushing the diode very much so as said before, its probably just a bad connection somewhere. As long as you don't inadvertently...

Also single mode diodes can be combined in several ways to increase the power and give you a better beam profile than a multimode. But again, the higher the power the more complicated doing it and more expensive. Knife edging, Cubes, Dichroics (am I missing any?)

Mines about the same power (maybe a tad less) and I got it from Sam also, but you have the advantage with the 604 line. Mine also has a special place of honor in my home. A shelf just for this HeNe and accompanying power supply, out of harms way. Be careful with it and be warned, another LPF...

I'm with you on that. I have a 575 lasence module and not sure what I'm going to do with it yet, but they are not easy to get and I'd hate to have mine go poof also :)

Pricey, but well worth it. Thank you for the beautiful pictures. I had thought I misread the heading or something. Very nice laser - I'm happy with my little 20-30mw 575nm, but I think I could be happier with that. :) Enjoy and be careful - and continue to post pics as you have opportunity

A-14-00 That would work but they are expensive! I recently priced one.

my 6" red nightlight is about .1 mw - but yours being yellow is very nice, especially that size. My yellow HeNe lasers are much longer. You should be able to power it with 3 or 4 - 18650 batteries. Post when you finish it, with a beam shot.

In 1978 I was taking an electronics class in High School and some magazines were selling laser diodes but super expensive. I desperately wanted to build a laser but it was out of my skill level and price range. In 1985 I started working for an electronics company and we sold "laser pointers" a...

Try this on for size. Posted 6 years ago https://laserpointerforums.com/threads/my-newest-collection.97811/ These were all done with vaping hosts that existed at the time. They are no longer available - most only cost about $20 for the base, plus the voltage monitor ($8) and the laser head...
