Observation of both second harmonic and multiphoton absorption induced luminescence in ZnO.

Dai, D.C. and Xu, S.J. and Shi, S.L. and Xie, M.H. and Che, C.M. (2006) 'Observation of both second harmonic and multiphoton absorption induced luminescence in ZnO.', IEEE photonics technology letters., 18 (14). pp. 1533-1535.

Abstract

The confusion over second-harmonic generation (SHG) and multiphoton-absorption (MPA)-induced luminescence in ZnO is observed under excitation with femtosecond laser between 800 and 1000 nm at room temperature. Excitation power dependence measurements show SHG is a two-photon process, and MPA is a three- or four-photon process. These are confirmed with interferometric pulse autocorrelation experiments. Excitation power density is a main regulatory factor for this confusion.
