Abstract :
The gain mechanisms and the lasing dynamics of ZnO nanorods are investigated in this work as a function of temperature and excitation power. Measurements are obtained using a streak camera which allows to resolve the onset and decay of the lasing emission on a ps-timescale for a single lasing peak. Observations show multimode lasing for some nanorods caused by higher excitation densities.
