摘　　要：在CdS单晶片(厚度为1～3μm)上,用Ar^+激光(λ=514.5nm)作光源,实现了室温热光光学双稳态(OB),记录了热光光学双稳态下的横向空间效应和开关波。研究了在热光光学双稳态和热击穿状态下晶体的不同性状,估算出相互独立工作的热光OB元件之间的最小距离为200μm。Thermo-optic bistability at room temperature has been obtained in CdS films (thinckness 1-3μm) excited by Ar+-laser ( A=514. 5 nm). The transverse effects and on/off waves was recorded in the thermo-optic bistability. Different behaviours of CdS crystals for the thermo-optic bistability and the thermo-optic breakdown was investigated. Minimum distance (200μm) between the OB elements that works separately has been calculated.
