Random Lasers Based on Mixtures of Micropowders of ZnCdSSe Solid Solutions and Phosphors Ca4Ga2S7:Eu2+ and Ca(Al0.1Ga0.9)2S4:Eu2+
Abstract
Random lasing was achieved in CdS and Zn0.65Cd0.35Se micropowders at optical pump levels of 0.1-2 MW/cm2 with N2-laser radiation at the wavelength of 337 nm. The values of the random generation thresholds were 820 kW/cm2 for CdS micropowder and 740 kW/cm2 for Zn0.65Cd0.35Se micropowder. The introduction of Ca(Al0.1Ga0.9)2S4:Eu2+ and Ca4Ga2S7:Eu2+ chalcogenides into the mixture to micropowders of CdS and Zn0.65Cd0.35Se solid solutions led in both cases to a drop in the random generation threshold to 520 and 550 kW/cm2, respectively, as well as to the appearance of the structure of laser radiation lines and an increase in their intensity. This may be caused by an increase in the number of feedback loops due to the introduction of additional scatterers.
