Pulsed electron beam pumped laser based on ZnCdSe MQW structure with high threshold of catastrophic degradation

摘要

The parameters of electron beam pumped RT lasers based on ZnSe-containing MQW structures were studied. Maximum value of output pulse power as high as 82W per laser facet has been demonstrated. Both the high value of Pmax and the threshold of catastrophic degradation in comparison with the earlier results could be explained by the relatively low level of defect density (∼104 cm−2) in the laser structure.
