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...

| description | 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<sup>2</sup> is measured to be <1.3, without observing transverse-mode instability. The standard deviation of the power fluctuation is quantified to be 0.6 W over a time span of more than 1 hour, at an output power of up to 100 W. |
