Occurrence of significant elastooptical effects in PbZrO3 single crystals under illumination by 10ns Er:glass laser at 1540nm wavelength was established. The effect is maximal for the off-diagonal piezooptical tensor component. It was found that during heating to the ferroelectric phase (at about 540K) this effect is substantially suppressed. The observed effect may be used for production of optically operated devices working at different temperatures.
► Substantial increase of the piezooptical effect in PbZrO3 is found during illumination by nanosecond Laser. ► Effect is very sensitive to the ferroelectric phase transition. ► The effect is caused by anharmonic electron–phonon interactions.
