abstract:
A new high-perfomance Yb:CaAlGdO4 (Yb:CALGO) regenerative amplifier is demonstrated. Pumped by 116 W at ≈ 980 nm and seeded by means of a 92-fs oscillator, it generates as much as 36-W of average output power with chirped pulses, and 28-W with 217-fs compressed pulses at 500-kHz repetition rate. This corresponds to 56-μJ pulse energy and 258-MW peak power. The compressed pulses have a time-bandwidth product of 0.69 and could be further shortened with an improved compressor setup.
