26 Jul Non-converted Infrared Upcycling Option
At Azurlight Systems, we produce visible wavelengths by frequency doubling of infrared light. This process not being completely efficient with our single pass architecture, there is still a consequent amount of unconverted IR light. Instead of dissipating it (by recoupling it by a multimode fiber to a beam dump), we propose to upcycle this single mode, single frequency, ultra-low noise radiation.
We thus inject it into an IR optical head, mounted next to the visible head on a breadboard. This optical head is equipped with > 35 dB of optical isolation, and you can expect for example about 20 W of 1064 nm upcycled from a 10 W 532 nm fiber laser.
