【摘要】 报道了在快速调制形成的准连续波激光照射下,观察到的P型HgCdTe电子非线性引起的光学双稳现象及其“开”、“关”特性。从低透射支到高透射支的“开启”时间和功率密度分别为10μs和1.5kW/cm~2。改变调制频率与调制器齿宽与齿间间隔的比率没有观察到热效应引起的入射-透射曲线变化。更多还原

【Abstract】 Using fast-modulated quasi-CW laser light, the optical bistability and switching characteristic due to electronic nonlinearity in P-type HgCdTe are observed. The up-switching time and intensity are about 10μs and 1.5kW/cm~2 respectively. No changes in the input-output characteristic due to thermal effect were observed when the modulation frequency and space-ratio of the modulator altered.更多还原
