Research abstract
Directed Energy Solutions is proposing to develop a compact, high-efficient cryogenic diode laser stack for optical pumping of a Yb:YAG laser. In phase I, Directed Energy Solutions will design, fabricate and test a 1 kW cryogenic stack. Multiple lensing techniques will be examined and tested. The operation wavelength will be 940 nm for efficient pumping of Yb:YAG. To accomplish this aggressive goal, Directed Energy Solutions will leverage existing cryogenic diode laser efforts, which have demonstrated world-record diode laser efficiencies of 84 % and the first all cryogenic Yb:YAG laser. In phase II of this effort DES will scale the device to the 5 kW level.
