We present a systematic investigation of thermal loading effects in single-stage high average power regenerative chirped pulse amplifiers based on Ti:sapphire. Using finite element analysis (FEA), we compute the temperature distributions, optical path deformations (OPDs), and corresponding thermal focal lengths for a variety of pumping conditions. We experimentally characterize thermal aberrations in a regenerative amplifier using a variety of techniques (interferometry, pump-probe thermal lens… CONTINUE READING
