We reported a compact, stable 12-picosecond Innoslab amplifier. A mode-locked seed laser with an initial power of 4.5W was amplified using a discrete beam path (DBP) configuration. The 1064nm Nd:YAG slab amplifier showed the high average output power of 165W at 1MHz of pulse repetition rate. The amplifier exhibited 16.6% of optical conversion efficiency. The long-term power stability of the laser system was calculated for one hour and the fluctuation was found to be 0.27%.
A high-average-power, laser-diode, end-pumped nanosecond multi-pass Innoslab Nd:YAG amplifier was demonstrated. With effective shaping of the electro-optically Q-switched Nd:YVO4 seed laser, a 45W seed laser at the pulse repetition frequency of 50 kHz was amplified to 212W with the pump power of 1145W, and the corresponding optical-to-optical efficiency was 14.6% and the slope efficiency was 17.8%.
