Facility is suitable for analysis of ultrashort pulses and light beams self-action processes in transparent materials.

Facility consists of:

I. Spectra Physics Ti:sapphire femtosecond system with noncollinear parametric amplifier and ultrashort pulses IR radiation source. Central wavelength of the amplified pulses is 800 nm, maximum pulse repetition rate 1 kHz, pulse duration 130 fs. Pulse energy at 1kHz repetition rate is 3 mJ. Noncollinear parametric amplifier generates <20 fs radiation in 550-750 nm spectral range. Ultrashort pulses IR source generates < 20 fs pulses in 2 m range.

II. Diagnostic complex, which consists of: high dynamic range Andor CCD camera, pulses duration meter Grenouille and unique set of diagnostic for space-time and spectral characteristics.
This set allows to record the spatial distribution of radiation in 300-1100 nm spectral range. Pulse duration in visible and IR spectral range and spectral characteristics in 200-2500 nm can be measured.
