100-W, 100-h external green generation with Nd:YAG rod master-oscillator power-amplifier system

A high repetition rate diode-pumped Nd:YAG rod master-oscillator power-amplifier system was designed, fabricated and tested. The system provides a maximum average power of 222 W at a repetition rate of 2.5 kHz with a pulse width of 51 ns. With an external two-stage KTP crystal architecture, this sys...

Description
Summary:A high repetition rate diode-pumped Nd:YAG rod master-oscillator power-amplifier system was designed, fabricated and tested. The system provides a maximum average power of 222 W at a repetition rate of 2.5 kHz with a pulse width of 51 ns. With an external two-stage KTP crystal architecture, this system produced a 131 W green average power with a frequency conversion efficiency as high as 65.2%. To examine the system reliability, the 100-h continuous operation was done at a green power level of 100 W. The decreasing rate of green power was observed to be 0.07% h −1.
