摘要
研究了温度对串联光折变晶体回路中高斯光束传播特性的影响.假设一束暗孤子光束和一束高斯光束分别入射到回路的两块晶体上,利用数值计算方法分析了改变暗孤子所在的晶体温度对高斯光束在另外一块晶体中传播特性的影响.结果表明,调节暗孤子的晶体温度能够影响另一块晶体中高斯光束的传播特性,可以决定高斯光束在晶体中是否能够演化为稳定传播的明孤子波.
Temperature effect on the dynamical evolution of Gaussian beam in an unbised series photorefractive(PR) crystal eircuit were investigated. When a Gaussian beam and a dark solution beam were incident on the PR crystal, respectively, then effectcs of changing the temperature of the on the propagating proprety of Gausssian beam were discussed by numerical calculations. The result shows that the dynamical evolution of Gaussian beam in one erystal can be modulated by changing the crystal temperature of the dark solition in the other circuit. By this way one can determine whether the Gaussian beam could evolve into a solitary wave or ont.
