Abstract

The report presents the basic principles of creation, scheme and the components of multiterawatt laser system at kilohertz repetition rate based on parametric amplification of femtosecond pulses and laser amplification of picosecond pulses for pumping of stages of parametric amplifier. On developed element base in pump channel of laser system, parameters of regenerative amplifier with output energies about 1 mJ at repetition rate of 1 kHz and central wavelength 1030 nm are experimentally investigated. Optical scheme of multipass cryogenic amplifier based on diode pumped Yb:Y₂O₃ laser ceramics is developed and parameters for increasing of output energy up to ~ 0.25-0.35 J are determined.
