法布里—珀罗标准具滤波器对超短光脉冲的时间响应

系统地研究了法布里－珀罗标准具滤波器对超短光脉冲的时间响应，由于光在标准具内多次反射所引起的干涉效应，发现输出的光脉冲包含了一连串的次脉冲，这些次脉冲的时间间隔等于光单次通过标准具的时间，在一定条件下，这些次脉冲简并在一起产生一展宽的输出光脉冲，并且输出和输入光脉冲峰值的时间间隔并不等于光单次通过标准具的时间，并得出了在考虑色散和啁啾情况下输出次脉冲的表达式。

Temporal Response of Fabry-Perot Etalon Filters to Short Optical Pulses

The temporal response of a Fabry-Perot etalon filter to the short optical pulses has been studied.It is found that due to the interference between the multi-reflected beams inside the etalon,the transmitting pulse is composed of a series of sub-pulses which are separated by the one-way traverse time of the light inside the etalon.Under certain circumstances,the sub-pulses merge together resulting in a broadened output pulse,and the time difference between the peaks of the output and input pulses may not be equal to the one-way traverse time. Studies have also been carried out for the chirped pulse and dispersion etalon, which led to the expressions of the transmitting sub-pulses.
