  1. Generation of broadband and multiple-peak THz radiation in aperiodically poled lithium niobate

  2. We theoretically analyze the generation of broadened and multi-peak terahertz (THz) radiation in aperiodically poled lithium niobate (APPLN), whose sequence of opposite domains is optimized by simulated annealing (SA) algorithm. The full-width at hal

  1. 非周期极化铌酸锂晶体宽带倍频的理论研究

  2. 宽带准相位匹配(QPM)在多波长和超短脉冲倍频等领域有着广泛应用。分析了铌酸锂晶体的准相位匹配和群速度匹配条件,利用遗传算法,对非周期极化铌酸锂(APPLN)晶体的结构进行优化设计,并提出了一种通过适当调整基波的位置和数量来优化非周期极化铌酸锂晶体倍频带宽的设计方法。研究表明,对于0型(e+e→e)准相位匹配,在群速度匹配点附近,周期极化铌酸锂(PPLN)晶体倍频带宽为167 nm,而非周期极化铌酸锂晶体最大倍频带宽可达440 nm,带宽增加了273 nm;I型(o+o→e)准相位匹配下,周期极

  1. Proposal of switchable multiwavelength laser with continuously tunable spacing in MgO: APPLN waveguide

  2. A switchable multiwavelength laser with a continuously tunable spacing is proposed and illustrated based on cascaded interactions of the second harmonic and difference-frequency generations in an aperiodically poled MgO-doped lithium niobate (MgO:APP
