摘要：

Optical gain spectra of ZnO epitaxial thin films have been measured by using a pump-probe technique. The optical gain is thought to be due to electron-hole plasma. In the differential absorption spectra, we observed saturation of the exciton absorption, band-gap renormalization, as well as the optical gain. From the temporal changes of these structures, the dynamical properties of the photoexcited carriers are discussed. (C) 1999 American Institute of Physics. [S0003-6951(99)01130-4].
