The present collection of articles sets forth the results of experimental research on physical processes in various types of optical quantum devices (lasers). Data are presented on the regulation of the temporal and spectral characteristics of solid-state lasers using a bleachable filter. A mode self-locking state is realized in which ultraflhort light pulses are emitted. The stimulated emission in a pinch discharge due to transitions of singly and doubly ion ized argon atoms in the visible and ultraviolet parts of the spectrum is investigated. Pulsed lasing associated with electron transitions in diatomic molecules at the leading edge of a power ful current pulse in a gas is subjected to systematic analysis. The book is aimed at a broad spectrum of scientists and engineers specializing in quan tum radiophysics.
