Abstract

We have developed a large-aperture, flash-lamp-pumped Cr:LiSrAlF6 (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.

(a) Measured small-signal gain in the 19-mm LiSAF amplifier as a function of electrical pump energy discharged through the flash lamps (squares). The dashed curve is the calculated small-signal gain, assuming a constant 1.8% pump efficiency, and the solid curve is the calculated gain when the UV shift of the Xe spectrum is taken into account. (b) Measured small-signal gain as a function of radial position in the 19-mm amplifier.
