It is shown that the values such as the gain, the phase conjugation reflectivity and the response speed increase as the temperature increases. At about 55, 71 and 110℃, extraordinary enhancement of the gain and the phase conjugation reflectivity were observed.The mechanism is analyzed by the phase change in the crystal at these temperatures.展开更多
