R. Mellish et al., ALL-SOLID-STATE DIODE-PUMPED CR-LISAF FEMTOSECOND OSCILLATOR AND REGENERATIVE AMPLIFIER, Applied physics. B, Lasers and optics, 65(2), 1997, pp. 221-226
We describe the development of a tunable diode-pumped Cr3+:LiSrAlF6 (C
r:LiSAF) regenerative amplifier, seeded by a diode-pumped Cr:LiSAF fem
tosecond oscillator. The amplifier produced pulses of less than 200 fs
duration and greater than 1 mu J energy at repetition rates of up to
25 kHz.
