180 W picosecond green laser from a frequency-doubled rod fiber amplifier

We report on a 180 W picosecond green laser from a frequency-doubled rod fiber amplifier. An Ytterbium-doped fiber master-oscillator-power-amplifier is designed to generate 704 MHz, 2.3 ps, 270 W average infrared power. 2.1 picosecond, 180 W average green power with diffraction limited beam quality is produced through frequency doubling. To our knowledge, it is the highest picosecond average green power from a single fiber-based laser system.
