Stimulated emission and excitonic bleaching in GaN epilayers under high-density excitation
Measurements of edge emission on a GaN epilayer under N-2 laser excitation demonstrate stimulated emission and gain. The mechanisms involved are investigated by using laser pulses of 250 fs duration to measure simultaneously the photoluminescence and the time-resolved reflectance near the band edge,...
