基于非周期极化铌酸锂晶体产生任意频率太赫兹辐射
Generation of arbitrary terahertz pulse in non-periodically poled lithium niobate
摘要
Abstract
The narrowband terahertz (THz) generation on lithium niobate (LN) crystals with non-periodically poled domain structures was demonstrated.To realize THz pulse shaping, the optimal domain structures were designed by uing simulated annealing (SA) algorithm, for arbitrary preset frequency components and intensities of THz radiation generation.It was demonstrated that this method is feasible in THz pulse shaping.关键词
