The modeling of thermal fields in high power multi-disk cryogenic laser amplifier

In this paper we focus on the second unit of multipass amplification of the cryogenic diode-pumped high power laser system operating at 1 kHz repetition rate. Thermal fields in the cooling system of the amplifier were calculated and compared with experimental data. Numerical algorithm based on 3+1D...

Beschreibung
Zusammenfassung:In this paper we focus on the second unit of multipass amplification of the cryogenic diode-pumped high power laser system operating at 1 kHz repetition rate. Thermal fields in the cooling system of the amplifier were calculated and compared with experimental data. Numerical algorithm based on 3+1D heat transfer equation is proposed. The results of modeling are discussed and analyzed.
