Abstract
Extremely high optical power density emission (107 W/cm2) was achieved with a new Zn‐diffused ’’window‐stripe’’ laser by eliminating the restriction of the catastrophic optical mirror damage (COMD). The maximum available optical power was at least one order of magnitude higher than the COMD threshold in conventional structures. Furthermore, gradual degradation due to the mirroroxidation has been reduced significantly under cw operation.Keywords
