A model for analyzing the polarization of linearly polarized light traveling through LiNbO3 crystal(LN crystal) cut at Brewster angle is presented,with the use of Jones calculus and Fresnel formulae. The relationship between the polarization state of transmitted light and voltage applied to LN crystal is given. The transmitted intensity of p-polarized light and of s-polarized light in different applied voltages is also analyzed. The experimental setup of Ho, Tm, Cr:YAG laser is established. There are three types of Q-switched lasers which include single LN crystal,the combination of LN crystal and LN slice placed at Brewster angle, and double LN crystals, respectively. The influence of voltage applied to LN crystal on the polarization state and energy of output radiation is then measured.
