A new scheme of a cascaded converter of the first harmonic of broadband cw laser radiation into the second harmonic (SH) with compensation for the group walk-off in cascades is proposed and investigated. The conditions under which high conversion coe

The approximation of interacting quasi-monochromatic plane waves is used to analyse the possibility of parametric generation of pulses with a frequency shift relative to the injected monochromatic signal. This problem is important for the development

An experimental setup for the in-depth optoacoustic tomography of biological tissues in vitro was constructed on the basis of quasi-resonant ultrasonic detectors with a near-maximal sensitivity. The possibility of probing the boundaries of layers dif

A longitudinal shift of the amplified and converted images of a beam focussed in a nonlinear component are determined. This shift is related to a change in the effective wave number in the course of parametric amplification. When the gain is consider

An automated IR spectrometer was constructed on the basis of a pulsed optical parametric oscillator tunable in the range 1.5 — 3.7 μm. An interferometer optothermal method with a phase-contrast system for recording the signal was adopted. When the

The properties of hybrid prism–grating dispersion systems are studied. The scheme of a prism–grating stretcher matched to a standard compressor in the phase dispersion up to the fourth order inclusive is developed for a petawatt laser complex bas

An approximate theory of parametric amplification and stimulated Raman scattering is developed for a pumping field which is incoherent in terms of the transverse coordinates and time. Expressions are obtained for the increments of the average field a
