Abstract

A Fabry-Perot etalon based on a Cu:KNSBN crystal with two surfaces essentially perpendicular to its c-axis has been, to the best of our knowledge, studied experimentally for the first time using the 632.8 nm radiation of a He-Ne laser as well as the 488 nm and 514.5 nm radiation of an argon ion laser. The reflectivity (when the refractive index grating has not started to build up) is due to the Fresnel reflection at the crystal-air interface. The transmittance and the finesse were found to be dependent on whether the c-axis is parallel or anti-parallel to the laser beam. The experimental data have been compared with the theory of He et al. The photorefractive gain parameter and magnitude of the refractive index grating were deducing and compared with those found by two-wave coupling experiment. The time dependence of the transmittance has been analyzed.
