Joule thief perpetual power 2 with amp test.

[cakins]

Power beaming research (pulsed laser energy to UAVs and satellites) has shown that solar panels have the highest response to monochromatic light in the near-IR wavelengths. Researchers use 940nm - 950nm laser diodes for best energy transfer.

If I were to feedback solar panel output back to the circuit, I would use a 940nm -950nm diode. Can the joule thief circuit power a laser diode instead of an LED? A laser would dump all of the light directly onto the panel and resolve any light dissipation issues with LEDs (no reflective boxes, etc.).
