Abstract

We report what we believe to be the first millijoule-class ytterbium-doped fiber laser system operating on the zero-phonon line at 977 nm. An actively Q-switched master fiber oscillator delivers nanosecond pulses (FWHM 12–32 ns) at adjustable multiples of 10 kHz repetition rates that are further amplified in an ultralarge core photonic crystal fiber amplifier. At the highest available pumping level, a maximal average power of 78 W was obtained for 32 ns pulses at a repetition rate of 190 kHz, whereas the millijoule energy level was reached for 12 ns pulses at the lower repetition rate of 10 kHz.
