Must be very niche as lasers operate typically below 10% efficiency. And one speck of dust or defect on a component and you're setting fire to something.

- Aachen 3y agoThe post says it > can provide 3v 180mA from 1.5W 0.18×3=0.54W, so like ⅓ efficient. Maybe that's why it's so expensive compared to other modules which can get away with lower efficiencies?
- hwillis 3y agoThat's the efficiency of the device, not the laser. This device does not include a laser. That said, I don't know of any diode lasers that are that bad. Lasers for this fiber are probably 50%+ efficient and even the high frequency laser diodes are still 30%+
- vanderZwan 3y agoThis would still make the whole system a lot less inefficient than I expected, tbh.
- auspiv 3y agoup to 45% efficient at lower power (0.5W in, 0.225W out) https://www.farnell.com/datasheets/2785190.pdf https://www.farnell.com/datasheets/2785190.pdf
- ajsnigrutin 3y ago> Maybe that's why it's so expensive compared to other modules which can get away with lower efficiencies? It's expensive, because most people don't need that, because they just use a wire to power their device. This has some very niche uses in high voltage insulation (where you need the power on the other side, but really really don't want high voltage to travel back down the line and destroy your device.
- namibj 3y agoIf you want efficiency you'd use iirc 405nm laser diode plus blue LED receiver.
