Paper Abstract

Pulse shaping experiments in a 100μm thick CdS-etalon have been performed with a pulsed frequency doubled Nd-Yag laser. The incident laser pulse produces changes in the refractive index and the CdS-etalon is tuned over a few resonances. From these experiments a refractive index change in CdS of Δn ≈ 0.0035 can be estimated. This value is larger than reported before for CdS at monitemperature. We report also pulse shortening experiments with the CdS-etalon. Finally, we have investigated the self-refraction of Gaussian laser beams in the CdS-sample. We observe self-defocusings which indicate that the dominant mechanism for the non-linear refraction is not of thermal origin.
