Tunable coherent radiation is generated in the vacuum ultraviolet down to 121 nm using random quasi-phase matching in strontium tetraborate, the shortest wavelength ever produced with a second-order nonlinear optical process in a solid-state material. Relevant properties of this radiation, the nonlinear process, and the nonlinear crystal are investigated.
利用硼酸锶中的随机准相位匹配,在真空紫外波段产生了可调谐相干辐射,波长低至121纳米,这是固态材料中通过二阶非线性光学过程产生的最短波长。研究了这种辐射、非线性过程和非线性晶体的相关特性。
