Osram PLP520-B1 520nm Green Laser Diode
Did a bit of testing on the new PLP520-B1 tonight. I was amazed with the spot size for a multimode diode. Compared to the M140 the spot size is about 1/3 the length. Based on this test 450-550mA probably is the sweet spot but more testing is needed to determine that.:eg:
Here is the spot size @ 25 feet.
