Near IR laser radiation is used for intrascopy of some types of human tissue. In particular, a tooth defect was studied by various methods of filtration of quasi-CW radiation scattered inside the object. The crucial points of this study are the emplo

An analysis is made of the stability of a plane monochromatic wave in a transparent isotropic dispersive medium exhibiting a cubic nonlinear polarizability. The frequencies of growing perturbations are obtained in the first approximation. In the seco

A periodic structure with intervals of 1–10 cm–1 was observed over a wide range of frequencies in the light scattered from self-focusing filaments in optical glasses. These results were obtained on application of single picosecond pulses of λ =

An image of an object (circular aperture), illuminated with radiation of λ = 1060 nm wavelength, was converted to the λ = 700–400 nm range. The conversion was performed in a sample of the K-8 optical glass pumped with picosecond pulses produced b

The emission spectrum of a mode-locked ruby laser was broadened to 5 cm$sup -1$ by a plane-parallel glass plate. The relaxation time of a saturable filter, which also influenced the pulse duration, was minimized by the use of solutions with a maximum
