Description
The effect of the length of ZnO nanorods on the mode structure and thresholds of stimulated and laser luminescence in the ultraviolet spectral region is studied. It is shown that nanorods with a metal mirror at the end face exhibit the minimum optical excitation power threshold in the case of long nanoresonators. Single-mode lasing is observed in short ZnO nanorods. Variations in the lasing thresholds are attributed to differences in the length of the amplifying medium and in the local densities of photon states in regularly shaped nanocrystals.
