摘要

利用3 ~ 4 μm的超短中红外激光脉冲研究了单晶和多晶光学材料的非线性光学特性。我们比较了两种材料的可见光和中红外光谱。在多晶材料中，测量到的能量转换成全阶谐波超过30%。

Generation of Broad Spectral Components from Mid-Infrared Ultrashort Pulse Laser Propagation through Single- and Poly-Crystalline Optical Materials

We investigated the nonlinear optical properties of single- and poly-crystalline optical materials using ultrashort mid-infrared laser pulses between 3 and 4 μm. We compared visible to mid-infrared spectra between the materials. Measured energy conversion into all-order harmonics in polycrystalline materials exceeded 30%.
