We present results of investigations of the directionality diagram and mode structure of radiation of semiconductor lasers with electron pumping that have microrelief reflectors instead of a blind mirror and output mirrors, whose coefficient of refle

Information on paths in absorption and deactivation of energy gained by molecules in their excitation by electron impact to low-lying singlet states has been obtained from an analysis of changes in the fluorescence spectra of these molecules. It is s

Stimulated emission in impurity organic crystals in pumping by a beam of high-energy electrons was obtained for the first time in 11 1. Analysis of the experimental data [1-41 shows that the effects of spectral narrowing and contraction of the durati

Stimulated emission and laser action under N2 laser radiation and electron‐beam excitation at room temperature was studied in ZnSe epitaxial layers grown by metal‐organic vapor‐phase epitaxy. The laser threshold was about Ithr=1 MW/cm2, the pul

The power characteristics of electron-beam-pumped emitters based on II–VI compounds have been stukdied. The use of a microrelief with direction-selective reflective properties instead of a totally reflecting miror has made it possible to provide ef

Stimulated emission was obtained from a new type of organic crystal, paraterphenyl activated with diphenylbutadiene, pumped by a high-power nanosecond electron beam. The radiation characteristics of the crystal were investigated and compared at vario

Recently [1] it was shown that the creation, by means of chemical etching [2], of certain microrelief on the anion surfaces of laser wafers instead a totally reflecting silver mirror permits increasing the output power of lasers based on CdSSe compou
