Monolithic Yb-doped femtosecond fiber laser with >300 W average power

In this submission, we report a maximum 638-W fiberized chirped-pulse-amplification (CPA) laser system with a bulk reflection grating compressor. The system is able to emit 338-W compressed pulses of 624 fs centered at 1 μm, corresponding to a pulse energy of 1.3 μJ at a pulse repetition rate of 258...

Zusammenfassung:In this submission, we report a maximum 638-W fiberized chirped-pulse-amplification (CPA) laser system with a bulk reflection grating compressor. The system is able to emit 338-W compressed pulses of 624 fs centered at 1 μm, corresponding to a pulse energy of 1.3 μJ at a pulse repetition rate of 258 MHz. The output beam quality factor M 2 is measured to be
