In our experiment, the ZnO nanoparticles(diameter about 100nm) are optically pumped by the third harmonics (355 nm wavelength) of a pulsed Nd:YAG laser (30Hz repetition ration rate, 8ns pulse width). Laser-like light emission was observed in the ZnO nanoparticles. We simulate the ZnO particle density transport versus mean free path using the ring cavity theory. The result shows that random lasing can be produced in the ZnO particle with Nd:YAG (pulse width 8 ns).
