26 Jul Infrared Upcycling
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.
