Optimal length of an electro-optical Q-switch with optical activity crystal La3Ga5SiO14

With the polarization plane gyration and the electro-optic effect existing simultaneously in an optical activity crystal, the theory on interaction of optical activity and electro-optic effect on the arbitrary linearly polarized light propagating through the crystal along the optical axis is studied. The electro-optical Q-switch is designed successfully. With the conclusion of the theory, the optimal length of optical activity crystal using as electro-optical Q-switch at a given wavelength is calculated. (c) 2005 Elsevier Ltd. All rights reserved.
