摘要

我们利用532nm的泵浦光束沿着方形晶格二维周期性极化钽酸锂(2D-PPLT)的x轴研究了特定的共同光参量生成(OPG)。由于K1,±1的倒易晶格矢量(RLV)的参与,信号或闲散光束与抽运光束共线传播,而另一个OPG对应光束则与抽运光束非共线传播。由于K1,0和K1,±1的贡献,还观察到多波长双光束的产生。

Shared and dual optical parametric generation in non linear photonic crystals of LiTaO3
We investigated specific common optical parametric generation (OPG) using a 532nm pump beam along the x axis of a square lattice two-dimensional periodically poled lithium tantalate (2D-PPLT). Twin-beam generation are observed with the signal or the idler beams propagating collinearly and the other OPG counterpart non-collinearly to the pump beam due to participation of reciprocal lattice vectors (RLV) of K1,±1. Multi-wavelength dual-beam generation are also observed due to contributions from K1,0 and K1,±1.
