Yes the laser is pulsed, but the fluorescence from the crystal (which I would be collecting) is pretty much continuous. That said, you all have made some very good points about economic feasibility. I think I may focus my efforts toward efficiency elsewhere. A sincere thank you to everyone who...

DC Supply is 12v. Not sure exactly what the pv output will be. I don't have a part number for the laser but it is a 10w IR laser diode requiring 6vdc. The laser driver module would limit current. The main power supply is 12vdc. The combined supply needs to supply 3 amps.

Baluncore, Thank you so much for your replies! You have been very helpful. I am almost ready, but just have 2 more questions. 1) My main power supply is a fixed voltage. If I leave the switching DC converter connected to the PV array, but put a capacitor to ground on the input to the...

Integral, why is this important? Since my light is nearly monochromatic, I should be able to achieve nearly 80 % with gallium arsenide cells.

Thanks Baluncore. Will the output voltage from switching converter (which I would use to make the voltage slightly higher than the mains supply) drop under load automatically or are there more necessary components? Is this how the main supply would 'know' to make up the difference?

Thanks for the reply. How would a small resistor help? In my system, an IR laser is absorbed by a crystal, then re-emitted at a higher frequency, cooling the crystal (anti-stokes fluorescence). It is this diffuse re-emitted light I will be taking power from. I just need the simplest way to dump...

Hello, I am working on a system where a laser does something and then there is a lot of wasted laser radiation. I want to capture this waste radiation in a small array of solar cells then feed the resulting current back into the laser to make it more efficient. The output from the solar cells...
