The high-energy system of the master oscillator-power amplifier based on the Ho:YAG crystal

The numerical modeling and the experimental research of the Ho: YAG system are done, which consists of the master oscillator and three power amplifiers. The doping level influence of the active elements on the laser oscillator work is researched. The conversion efficiency of the pumping reached 10% when the pulse repetition rate was about 100 Hz. The beam propagation-factor is ∼ 1.3.
