I am selling a laser using the Mitsubishi ML501P73 diode ran at 1A, which gives me ~800mw. The laser was built by me recently, but I am now selling it because the laser is too powerful for me, and I am too irresposible and scared I'll hurt myself or someone else. Here are some photos of the...

I have a 800-ish mw 638nm laser. I would like to sell it but I have no one to sell it to. If there is someone on this forum who might be interested, I would gladly provide more info.

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F332016073893 I have checked out the datasheet which says this is a "hologram laser diode". I still don't understand anything about it and what it does.

I was wondering, are there any low-ish power (5-50mw) 450, 405, 447 etc. nm laser diodes? All of the blue diodes DTR has are 500-7000mw (excluding the Sharp 488 diode).

Is this a good lens to buy for the mitsubishi 638nm 500mw laser diode? https://www.ebay.com/itm/638nm-Laser-Diode-Collimating-Coated-Focus-Lens-MP9x0-5x10-5-Half-Threaded-Frame-/141819513641

Ok, educate me on dummy loads, please. For instance, if I have a 1A driver, and my laser diode is supposed to work on 2.2v, how many diodes do I need in a dummy load? How do I calculate these things, and what do I even need to calculate? I know I should probably know these things, but I don't...

So I have a survival lasers c6 host and a fixed current driver. My question is can I put the driver into the pill WITHOUT a brass ring? Also, some components on the board are touching the the pill, is that supposed to happen?

I might do a 488 build sometime in the future, so I was wondering how bad (or good) is the divergence and "range" of the laser.

So I want to buy the Mitsubishi 500mw 638nm laser diode, and I found this one on ebay...

I'm looking for a 1W green laser diode with an actually circular beam and good divergence? If there even is such a thing. Sorry in advance for the stupid question.

So, I was thinking, is it safe to run the Mitsubishi ML501P73 diode with 1A in cw mode (I'd run it 5-10 seconds on, minute off duty cycle, if that works.) I know I'd need adequate cooling, but I'm just scared of frying the diode. Thanks.

Are cheap eBay laser diode drivers such as https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F262878776688 safe/good to use? If not, why?

So I was wondering, can I set a max current output for the flexdrive? Say that I somehow set it to 800ma, and then when I turn the potentiometer the max it can go is 800ma. I am asking this because I've been thinking to wire a bigger potentiometer to the driver so I can control the laser's...

Just imagine, how cool would it be if we hade white laser diodes.

As you might know, 589nm (amber yellow) lasers are difficult to produce, insanely unstable and very expensive. Just like 488nm (cyan) lasers were a couple of years ago, but then Sharp came out with a 488nm diode, now you can get them for like $30. So I've been wondering, do you think Sharp, or...

Alright, so today I pressed my first diode. The press was successful, but I damaged the diode a bit... It's not too bad, I don't think. But I know these things are very sensitive. So what is my prognosis? Is it busted or is it fine?
