Simulation and optimization of a polarized nanosecond hybrid Ho3+ and Tm3+-doped silica fiber & Ho3+:YAG MOPA at 2048 nm targeted for ZGP OPO pumping

Ho3+:YAG amplifiers are able to efficiently scale the pulse energy at wavelengths as short as 2048 nm. While maintaining 5.3 dB gain, an output power of 81.6 W and a slope efficiency of 68 % is achieved.
