Nice to meet you Mr Bowtie!

Thank you very much for that! Very informative! Exactly what I needed!

Hey again everyone, my last post was talking about problems with creating a 300mw laser with one of those cheap laser diodes from eBay. Since then, I've go that working, and have also made a 200ish mw blu-ray laser from a blu-ray sled laser diode. I have pulsed it at like 80Hz with a 555...

Thank you very much! You're a saint. im willing to overlook the safety part because you sound like a top guy and wasn't like: "You fukn N00b, get goggles" Cheers.

G'Day there again folks. So yesterday I managed to get my 300mw 808nm infrared laser running. I made it by buying the diode, and the housing, and each part individually off eBay. Basically its not burning anything yet, (due to either batteries not rated to put out enough mA, or just scummy...

But can someone please link me to the site where I can get a module for my infra-red diode? Preferably the Aixiz module? Also, I have other lasers which are all visible light, but cant burn anything. So this is why I'm starting with a burning one.

Thanks for the help! Could you possibly send me a link to the 5.6mm Aixiz module? I'm not sure I can find the one you mean.

I don't really know what you mean by reflective casing, but I think you may mean the plastic which usually covers the top of the diode? If so my laser diode doesn't actually have one of them.

Also, will I be able to see any of this damage with a microscope? Because I could have a look through mine. Obviously not while it is on.

Simply because of the cost. When I get a working IR laser diode going. Then I will delve into the area of visible light. But I don't want to break any of those, when they cost about $50. So I am gaining some experience first. And you're helping fantastically.

I'll take a picture for you. I didn't use anything at all. I feel like the vibe I'm getting from you guys is that I have blown it. No heat sinking or anything for the diode, because I'm new to building lasers. I take it that it must be essential. :D Thanks for the help by the way guys!

Ok, thanks! Ill order another diode just because I can, (only cost like $4) and Ill buy this module. Thanks! Will the laser disparate incoherent light, if it isn't in a module? Even if the laser diode is in perfect working condition. It is a 5.6mm diode, so I'll get on that. Thanks again...

Hey guys, this is my first post, but I've been following this site for a long long time. I have finally ordered in all my parts to make a LM317 laser driver for my 300mw 808nm laser diode. And I connected everything up after testing, and all went well. The laser diode came on at an output of...
