Abstract

A diode pumped single rod Yb:YAG amplifier for pumping high repetition rate OPCPA was developed providing high energy nanosecond pulses with 20 Hz repetition rate. A ring–shaped resonator was built with a number of round trips controlled by a BBO Pockels cell. A module with stacks of laser diodes with a possibility to provide 5 kW peak power at 50 Hz for future upgrade was implemented in order to provide double-sided end pumping. Active cooling by thermoelectric cooler and flowing water, crystal’s undoped endcaps and housing architecture yielded in high gain and low lensing effect.
