A time compressor of femtosecond laser pulses is developed using supercritical xenon as an active medium. Laser pulses with a duration of 300-fs and an energy of 8 μJ are compressed to 23 fs with an efficiency of 40 %.

An autocorrelator based on the noncollinear generation of the second harmonic in a crystal for duration measurements of single sub-10-fs laser pulses was developed. The measured pulse duration of a broadband laser system was 6.2 fs.

The conversion to the first Stokes component at a wavelength of 1.8 μm of ytterbium laser radiation with a pulse duration of 270 fs by stimulated Raman scattering (SRS) in hydrogen was carried out by using double-pulse pumping scheme. Simultaneously

We report the temporal compression a femtosecond ytterbium laser pulse at a pulse repetition rate of 100 kHz using the effect of nonlinear self-phase modulation in a gas-filled capillary. A 260-fs laser pulse is compressed down to 17 fs with an energ

A femtosecond Raman laser utilising compressed hydrogen is experimentally investigated under pumping by radiation from a 1-kHz-repetition-rate Ti : sapphire laser. In the regime of double-pulse pumping, the conditions are determined, which correspond
