We report a diode-pumped high-repetition-rate chirped-pulse Yb:KGW regenerative amplifier delivering tens of microjoules pulse energy at repetition rates of up to 300 kHz. High repetition rates are obtained by using an acousto-optic modulator as switching element in the regenerative amplifier cavity. The output pulses were compressed down to 600 fs pulse duration. Even shorter pulses in the 100 fs range are obtained using an amplifier configuration without chirped pulse amplification.
