Lasing dynamics in single ZnO nanorods

Opt Express. 2008 Jan 21;16(2):1125-31. doi: 10.1364/oe.16.001125.


We study the lasing dynamics of individual ZnO nanorods by time-resolved mu-photoluminescence. The distinct laser modes show gain competition and pronounced shifts as a function of excitation density. This behavior can be understood in terms of many-particle effects within an inverted electron-hole plasma and of the calculated mode spectra of the particular nanorod, whose geometry is known from electron microscope investigations.
