摘要:
描述一种非周期极化结构晶体中多频率太赫兹辐射波的产生.在此非周期结构的LiNbO3超晶格中,基于飞秒脉冲二阶非线性光学整流效应,模拟多频率模式的太赫兹波形.通过选择最佳畴宽度,得到转换效率基本相等的3个主要太赫兹频率模式.该方法对多频率模式的个数无限制,且有助于多频率激光器中超晶格晶体的设计.
Abstract:
Generation of multifrequency terahertz radiation in a designed aperiodic poled structure was described.In such a LiNbO3 superlattice with aperiodic structure,terahertz waveforms with multifrequency modes were simulated,based on the second-order nonlinear optical rectification effect of femtosecond pulse.By choosing optimal domain width,the conversion efficiency of three primary terahertz frequency modes is nearly equal.No restrictions are placed on the number of multifrequency modes.The method may be used for the design of superlattice to construct multifrequency laser.
