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 around 100mw, and continued to get brighter until I couldn't actually make it any higher at around 800mw input. (Which is ridiculously strong. But fantastic, because I'm looking for some solid burning action.)
The only problem is the laser diode seems to be emitting incoherent light, in all directions like an LED rather than in a coherent beam like a laser diode. I was wondering if most lasers do this, and mine just needs a casing, or whether there is something wrong with my laser diode.
How do I focus it? So it is in a beam, so I can get down to the burning part.
Please don't even mention safety, because i'm not new to electronics and lasers in general, just new to making them, and please dont ask why I want a burning laser, because obviously I want to burn things.
Thanks!
