摘　　要：用TEA CO_2激光器输出的脉宽为100ns(FWHM),波长为10.6μm的激光脉冲,在室温下入射InSb F-P标准具,得到了双光子机制的光学双稳性。从非线性F-P标准具理论出发,对上述过程进行了计算机模拟。在相似条件下,改用高斯光束入射,发现由此形成的自散焦效应,使输出产生明显不稳定。: Irradiating an InSb etalon with TEA CO2 laser pulses at 100ns (FWHM), optical bistability and instability were obtained respectively by two-photon excitation and self-defocusing under Gaussion beam at room temperatures. Based on the F-P nonlinear etalon theory, computer simulation of optical bistability was made for the above process. It was found that the self-defoeusing thus formed would lead to obvions instability of the output when a Ganssion beam was used at similar condition.
