Abstract
A light pulse from an ultrashort pulse light sourceis split by a beam splitterand guided, to a detection medium, as an excitation pulse and probe pulse having respective predetermined linearly polarized states by an excitation optical systemand probe optical system, respectively. A light track region which is generated in the detection mediumby incidence of the excitation pulse, and in which the refractive index is changed by a nonlinear optical effect, is irradiated with the probe pulse. Of components which have passed through the detection medium, a probe pulse component whose polarized state has changed through the light track region is detected by a cameravia an analyzerin a photodetection part. This realizes a light track observation apparatus capable of directly observing the light track of an excitation pulse.
