Reddit reviews 2W 445nm M140 Blue Diode in Copper Module W/Leads & Three Element Glass Lens

This is the driver: http://www.ebay.com/itm/5A-analog-linear-PWM-laser-diode-driver-with-thermal-protection-/162291013120?hash=item25c94c5600:g:w7oAAOSwiYFXHE-T
I have a feeling that maybe the driver isn't allowing the full current through to the laser.... I'm considering running without the driver and seeing how that goes.

>(I may get some basic online courses on electrical engineering or optical science if thats a good idea)

Electro-optics is literally my major so ask away


But 10W is insanely too much power for any application other than engraving or bring reckless.

For a first build i would recommend not going above 10-20mW because of how dangerous it gets. But you can buy lasers built into housings like this and use a lighter driver
