摘要

钽铌酸钾(KTN)晶体具有很高的二次电光系数,响应速度快,因此可以作为高速电光开关的材料,能在较低电压下快速产生大的光束偏转角。但是 KTN 晶体的色散问题制约了其作为电光开关在宽光谱范围内的应用。探讨了外加电压、温度及波长对偏转特性的影响,发现同时调节电压和温度的方法可以平衡光束偏转角和色散,为KTN晶体用于宽波段光束偏转提供参考。

Abstract

The potassium tantalate niobate (KTN) crystal has a high quadratic electro-optic coefficient and a fast response speed; therefore, it can be used to develop a high-speed electro-optic switch, which can quickly achieve a large beam deflection angle at a low voltage. However, the dispersion problem of the KTN crystal limits its application as an electro-optic switch in a wide spectral range. We investigate the effects of control voltage, temperature, and wavelength on the deflection characteristics of the KTN crystal, and find that simultaneous adjustment of voltage and temperature can balance the beam deflection angle and dispersion. This study provides guidance to the application of KTN crystals in wide-waveband beam deflection.
