Amplification of femtosecond pulses to 1 J in Cr:LiSrAlF(6).
We have developed a large-aperture, flash-lamp-pumped Cr:LiSrAlF(6) (Cr:LiSAF) amplifier for use in a femtosecond chirped-pulse amplifier system. Optimum design of the 19-mm-diameter amplifier results in a single-pass gain of 5 with good beam quality. This amplifier produces 1.05-J pulses after compression, with a width of 125 fs at a repetition rate of 0.05 Hz.
