Actively pulse shaped linearly polarized nanosecond hybrid Ho3+ and Tm3+-doped silica fiber & Ho3+:YAG MOPA at 2048 nm

Ho3+:YAG amplifiers are able to efficiently scale pulse energy at wavelengths far shorter than the main emission peak. For 24 W input power at 2048 nm a signal output power of 81.6 W is reached, resulting in 5.3 dB gain.
