Degradation processes in II-VI-compound-based electron-beam-pumped lasers and creation of material with uniquely high optical strength

摘要

The processes of gradual degradation as well as the destruction processes of high power electron beam pumped lasers have been studied. The main reason of gradual degradation has been shown to be the increase of dislocation density due to thermoelastic stresses caused by both electron beam treatment and own laser radiation. The types of macrodefects which are responsible for laser screen destruction have been identified. CdS crystals obtained by the method developed by us were shown to have the highest optical strength.
