High power fiber MOPA based QCW laser delivering pulses with arbitrary duration on demand at high modulation bandwidth

Petkovšek, Rok (author), Novak, Vid (author), Agrež, Vid (author)

We report on a concept of a fiber MOPA based quasi-CW laser working at high modulation bandwidths up to 40 MHz capable of producing arbitrary pulse durations at arbitrary repetition rates. An output power of over 100 W was achieved and an on-off contrast of 25 dB. The laser features a dual-channel (dual-wavelength) seed source, a double stage YDF amplifier and a volume-Bragg-grating-based signal de-multiplexer. Minimization of transients was conducted through experiment and model analysis.
