Light coupling in Y-cut doped lithium niobate crystals
Y向切割掺杂铌酸锂晶体中的光耦合

We experimentally study the light coupling behaviors between the transmitting light and reflected light in y cut lithium niobate crystals. When the e polarized incident light is launched into the crystals along y axis and - y axis, respectively, we find that the time behaviors of the reflectivity and transmissivity are almost identical for both cases, respectively. Whereas when the o polarized incident light is launched into the crystals along y axis and - y axis, respectively, the time behaviors of the reflectivity and transmissivity for both cases are obviously different. We investigate the physics mechanism of these phenomena preliminarily.
