NDG700 700mW 520nm Laser Diode

These big 520nm diodes are a wet dream come true for me, but man are they expensive. 3 years from now I want 2 watts for 100 dollars. Its a steep expectation, but let me dream

Lol maybe when the 5 watts come out. But by then 2w won't be all that great.

I would try, with a q tip, it should work. good thing is 9mm diode windows are bigger, and therefore easier to clean. I've done it many times. 3.8mm diodes like the 520 osram are a PITA

Thanks. I tried with just a q-tip to no avail. So I tried dipping one end in 91% isopropyl alcohol and wiped with that end plus the dry end. Then I used a squeeze bottle to blow on it. That worked, looks much better.
