Abstract

Abstract: We report the temporal compression a femtosecond ytterbium laser pulse at a pulse repetition rate of using the effect of nonlinear self-phase modulation in a gas-filled capillary. A laser pulse is compressed down to with an energy efficiency of 40%. An average radiation power at the compressor output is . At a second compression stage, the time contrast is increased and the pulse duration is reduced in the process of the second harmonic generation in a KDP crystal. The obtained pulses have a duration of at an efficiency of 35%.
