【摘要】 <正>六十年代初,国际上开始了某些半导体材料非线性吸收效应的研究,他们在实验中相继发现CdSe、CdS、InSb、Ge、GaAs、ZnTe等半导体化合物单晶在不同波长的激光作用下都出现非线性吸收效应.同时还发现将上述某些半导体化合物如CdS、CdSe掺入玻璃基质中,制成具有一定本征吸收限的颜色玻璃,在相应波长的激光作用下也具有非线性吸收效应.更多还原

【Abstract】 Laser experiments on three types of glasses doped with CdS,CdSe, PbSe;In2Te3 semiconductor compounds have been made. We observed nonlinear optical absorption effects of transmissivity varying with laser intensity at different laser wavelengths. When the glass samples were placed in the cavity, modulation effects of laser pulse were also observed.更多还原
