Development of a high energy diode-pumped chirped pulse amplification laser system for driving soft x-ray lasers


Abstract: There is significant interest in the development of compact high repetition rate soft x-ray lasers for applications. This dissertation describes the development of a high energy, laser diode pumped, chirped pulse amplification laser system for driving soft x-ray lasers in the 10-20 nm spectral region. The compact laser system combines room temperature and cryogenically-cooled Yb:YAG amplifiers to produce Joule-level pulses with 5 ps duration at high repetition rates. A room temperature pre-amplifier manteins bandwidth for short pulse operation and cryogenic cooling of the power amplifier enables the high average power operation of this system. This laser was used to drive a soft x-ray laser on the 18.9nm line of nickel-like molybdenum. This is the first demonstration of a soft x-ray laser driven by an all diode-pumped laser.
