## Abstract

IR induced piezo optic effect (POE) in PbTe:Ca crystals was found under the influence of nanosecond pulse CO2 laser with a wavelength of 10.6 micro meters. It was shown that addition of Ca leads to an increase of the POE tensor coefficient. This indicates the appearance of enhanced IR induced static dipole moments caused predominately by Ca impurities. Simultaneously, the variations in time kinetics for the POE in nanosecond time regime were explored. A substantial role of electron phonon subsystem in the observed POE effect was demonstrated. The studies were done both for diagonal as well as off diagonal POE tensor components.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
