Paper Abstract

We report on the design and performance of an improved copper vapor laser pumped amplifier for femtosecond optical pulses. Consideration of the large duration mismatch between pump and seed pulses, the short energy storage time of the gain dye, spatial mode matching, and polarization effects led to an amplifier design of 1.5% efficiency, which is greater than previous designs. Pulses of > 10 tJ energy and -65 fsec duration are generated that are focussable to less than twice the diffraction limit. The multiple pass amplifier incorporates optimized mode matching, an antireflection coated flowing dye cell, and a polarized, spatially smoothed pump beam.
