摘要：
Two Yb3+-doped KGd(WO4)(2) chirped-pulse regenerative amplifiers, one under direct diode pumping and the other under pulsed Ti:sapphire laser pumping, are demonstrated. A slope efficiency as great as 43% is achieved from the free-running bare cavity of the diode-pumped amplifier, and 72% from that of the Ti:sapphire-pumped. When injected, the diode-pumped amplifier produces 44 muJ, 390 fs pulses at 1 kHz, and the Ti:sapphire-pumped amplifier produces 16 mJ, 1 ps pulses at 1 Hz, following compression.
