Abstract

We report a very efficient nonlinear optical conversion in thin films of wide band-gap materials. Very high conversion efficiency to the third harmonic radiation is achieved for an unamplified femtosecond Cr⁴⁺:forsterite laser in a sub-micron-thick film of a nanocrystalline ZnO pulsed-laser deposited on a fused silica substrate. Both the nonlinear optical coefficient and the coherence length are measured for film composed of 10-nm nanoclusters.
