looking to get a very small drive for this diode, if some one has a link to one could you send it to me thanks, that has been tested!
Wonder if these new lens make much difference in power:
520 550nm Green Laser Glass Collimation Lens for OSRAM PL520 5 Pcs | eBay
I still have this laser, and it's neat to have. I bought this laser mostly for novelity (after all, it's my first homebrew Gallium-Nitride handheld laser), and later on holography use. The green shade's nice (pretty much the same color as the recent green GaN LEDs), and the divergence is just unbelievable even for the single-mode diode.
Interestingly, the pundy 5mW green laser pointer I bought from Radio Shack displayed somewhat yucky yellow shade compared to this laser diode and I gotta agree with some peoples that without the green DPSS laser to compare with, it would be mistaken for the 532nm DPSS laser which it obviously is not.
And nice thing about DTR's bundled Microboost switchmode driver is that it have consistient cutoff voltage at 2.4 ~ 2.2 Volts, making this laser option perfect for the usage with single unprotected 3.2 Volts Lithium : Iron Phosphate cell, which I have been using my laser that way (with the A123 18650 Li : FePO4 cell) ever since I assembled it.
