摘要：

Recently developed lens-free heterodyne transient grating technique was applied to samples with rough surfaces on the order of several microns and photo-induced transient responses were successfully obtained on the temporal order of picoseconds. It was shown that the limitation of the sample roughness considerably reduced, compared with other conventional ultrafast methods. Theoretically the sample roughness was allowed on the order of 100 microns under our experimental condition, while it is on the order of several hundreds nanometers using a transient grating method.
