摘要
两表面镀有高反射膜,自身形成F-P腔的CdSSe玻璃薄片置于环形腔中.在一定的输入光强参数下,反射光信号出现其有某种规律性的振荡.实验观测了作为输入光强函数的不同振荡模式.由于所用样品的光双稳回线宽阔,上下两支有较大的倾斜度,我们观察到较大数目的输出强度上升与下降台阶.简单的绝热模拟表明,自振荡的模式遵从Farey-tree结构.
We investigated the thermal induced optical nonlinearity of a CdSSe- doped glass JB-7 made by Changchun Institute of Optics and Fine Mechanics. A slice of this glass coated on its both surfaces with high reflective dielectric films formed a Fabry-Perot resonator. The reflected light signal from the F-P resonator was coupled into a hybrid ring cavity,the round trip time of which was much longer than that in the F-P resonator and even longer than the thermal relaxation time of the glass.The self-oscillations occuring for certain input parameters were regular and the appearence of different modes as a function of the light intensity falling onto the resonator was observed. Due to the broad hysteresis and the high inclination of both branches of the bistability large numbers of increasing and decreasing steps in the output intensity were observed. A simple model of adiabatical simulation by an iterated map shows that the mode structure follows the Farey-tree construction.
