Ordered this: SF501B 445nm Blue
in 2W today, now the waiting begins. What can I expect from a blue laser, I have 405s, 532s, 640s, but this is my first high powered blue. Anyone got one?
So after a few year hiatus I am back at lasers. Now I am looking to build a very small blu-ray pointer. It will use a disposable E-cig as a host. The driver is in its own thread since I am curious to how it works and is it safe to use for these diodes: 405nm 150mW Blu Ray Burning UV Laser Diode...
I took apart an old red I had laying around (it was pretty bright), and found a 5.6mm diode in an 8x13mm module with a driver. It was a 3 volt driver, so I hooked it up to a 3.7 volt I scavenged out of an old E-cig (3.746v tested) and a red LED, 2.4v at 80mA. Out of curiosity I hooked it to a...
