Thanks for all the information. :)
I ordered some of these modules now.
Do you think I need an additional heat-sink for a DVD burner diode?
At how much mW could I safely drive them? And for how long at a time?
Do you think 15secs at 200mW would work without additional cooling?
I'm planning to take apart a few old DVD burners, but I want to order some heatsinks first. That's kind of hard though because I don't know the form factor of the diode. (you know, TO-18, TO-5 etc )
Any idea what I have to expect?
I was planning to buy the diode from odicforce: Nichia 1W+ 520nm Green Laser Diode (9mm) NUGM01T with Ball Lens (extracted)
But it doesn't come with a "module" (what does that even mean?). The price is really good though and they are in the EU (...err well not anymore, but at least they are in...
I'm thinking about buying one of those 1W 520nm diodes. I think "NUGM01T" is what they are called.
I have built a handheld laser before, but it was easy because I just needed to solder a diode to a driver and put everything in a flashlight-like case. And everything fitted in perfectly.
