Desperately needed 808nm drivers

[Photonjunky]

I am looking to use 2 and 3-watt 808nm C-mounts as pumps for 532nm systems. I need a driver with the following characteristics:

3.7-4.2 V input (single Li-Ion or equivalent)
Capable of delivering 2 to 4 A at 2V, fully adjustable Ultimately, maybe a version that could power 5, 8, or even 10W diodes.
Must have all the usual features...reverse polarity protection, low noise, soft start, low voltage and high-temp cutoff.

Does such a thing exist, or am I chasing unicorns?

Well...been nearly a year, and I see no responses. Is there no interest among the electronics wizards in creating such a thing? High-power 808nm diodes are still necessary for the construction of high-power DPSS lasers. I'm looking to build (and repair) several 1-2W 532nm systems. I do have an IPG Q-switched system that outputs just under 22W average power at 532nm, at 600kHz. It's very impressive, but not very portable (a guy on eBay currently has the 40W version, fairly cheap). So, the need for a reliable, high-current 808nm driver that runs on one Li-Ion battery continues. I'll pay anything reasonable to get this done.

Are you building a flashlight style laser, maybe you could use one of the round battery board drivers?

This forum went down hill starting about 5 years ago and now its almost dead.
Its a shame as back in the good days you would 50 responses.

Listen to RedCowBoy as he is one of the great ones and I lurks the forum once in while still I think.
