摘要
用计算机数值模拟方法对非线性光学界面反射特性的数值研究表明,有限宽度平面波光束的反射特性明显不同于高斯光束;前者较后者有较低的阈值光强来实现界面由全反射到部分透射状态的转变。
By numerical simulations of the reflection of a (2-D) limited width-plane-wave(LWPW)beam from a nonlinear optical interface,we show that its reflective characteristics are clearly different from that of a Gaussian beam.The LWPW beam has a lower threshold of input intensity at which there will be a sudden switch from total internal reflection (TIR) to a state with both transmitted and reflected beams.
