本文报道了硼酸盐玻璃中掺杂半导体微晶CdSxSe1-x的简并四波混频。当实验中采用波长λ=0.532 μm,脉宽tp=8 ns和tp=6 ps的脉冲进行四波混频时,测得CdSxSe1-x。的三阶非线性极化率x(3)的值分别为～10-9～10-8 esu和10-11 esu,瞬态光栅的衰减寿命为30 ps。实验装置的时间分辨率为6 ps。

In this paper, degenerate four- wave mixing in borosilicate glasses doped with crystallites of the mixed semiconductor CdSxSe1-x is reported. When the experiments were performed with the light pulse at wavelength A=0.532 μm, pulse-durations tp=8 ns and tp=6 ps, these semiconductor-doped glasses exhibit third-order nonlinearities x(3) of -10-9～10-8esu and -10-11 esu for DFWM with 10 ns and 6 ps laser pulses, respectively. The experimentally measured decay time of the gratings is 30 ps, with a time resolution of 6 ps.
