Abstract
Q-switching of Er:Cr:YSGG laser with transparent PLZT ceramics electro-optic modulators is reported previously.1 The extremely large quadratic EO effect in PLZT allows to built small size switches for the midinfrared spectral range with moderate control voltages. The high induced birefringence in PLZT results from an essential contribution to polarization (and consequently to the birefringence) of processes with longer relaxation times up to seconds, corresponding to the Er:Cr:YSGG laser operating rate.
