定量研究了纳米无序钽酸钾（KTN）晶体的电光效应。发现纳米无序KTN晶体的电光系数不仅与冷却温度有关，还与冷却速率有关。通过采用较快的冷却速率可以获得较大的EO系数。在0.45摄氏度/秒的冷却速率下获得克尔EO效率（s（11）-s（12）= 6.94 × 10（-14）m（2）/V-2）。通过采用更快的冷却速率来增强EO效率将极大地有益于各种应用，诸如激光Q开关、激光脉冲整形、高速光学快门和调制回射器。(C)2013年美国光学学会
The electro-optic (EO) effect in nanodisordered potassium tantalate niobate (KTN) crystal is quantitatively investigated. It is found out that the EO coefficient of nanodisordered KTN crystal depends not only on the cooling temperature but also on the cooling rate. A larger EO coefficient can be obtained by employing a faster cooling rate. A Kerr EO efficient (s(11)-s(12) = 6.94 x 10(-14) m(2)/V-2) is obtained at a cooling rate of 0.45 degrees C/s. The enhanced EO efficient by employing a faster cooling rate will be greatly beneficial for a variety of applications such as laser Q switches, laser pulse shaping, high-speed optical shutters, and modulating retroreflectors.
