Abstract

We present refractometric measurements made in the 266–1064-nm spectral region with a pulsed Nd:YAG laser, and the second, third, and fourth harmonics of the laser’s fundamental wavelength. The critical angle is determined by the disappearance of the diffraction orders from a metal grating, forming a microcuvette with the prism’s reflecting wall. A fused-silica measuring prism is used in the experiments.
