Outstanding Discovery of the XX-th Century — Lasers: Perspectives of Using for the Big Cities Needs

Abstract

A study of laser facets at high optical power density levels resulted in elaboration of a new characterization technique for laser diodes . A new facet coating system based on ZnSe was applied to InGaAsP high power laser diodes. These lasers emitted 2.85 W optical power in continuous operation that is the highest value in this material system . The results of medical applications of laser-diodes-based therapeutic apparatus in Moldovan and Romanian medical institutions are reported as well.
