Abstract
In this paper, we study some components of a terawatt femtosecond laser system operating with a pulse repetition rate of 1 kHz under development. The system consists of optically synchronized pump and amplification channels; the amplification channel is based on parametric amplification in an LBO crystal, and the pump channel is based on diode-pumped Yb3+-doped laser media at 80 K. In the pump channel, picosecond pulses are generated. The system is based on the chirped-pulse amplification technique. For the pump channel, parameters and alignments of the holographic grating-based stretcher-compressor system are determined. A diode-pumped (up to 1 kW) Yb:Y2O3 ceramic multipass amplifier operating at 77 K was designed. The data can be used in the development of cryogenic multistage femtosecond laser systems operating in a kilohertz pulse-repetition-rate mode.
