Optical damage resistance in a pure congruent lithium tantalite crystal

الملخص EN

The optical damage resistance has been investigated on a pure congruent LiTaO3 crystal by the measurement of the photo induced birefringence changes as a function of an Ar-laser irradiation time and intensity.

From these measurements, the intensity dependence of the saturation value of the birefringence and the photoconductivity have been extracted.

The so obtained results are compared to that of a pure congruent LiNbO3 crystal.
