| 摘 要： | 研究了用于测量两束光频差的时间延迟激光感生双光栅的频谱分辨率，确定了当泵浦光具有高斯线型时四波混频信号的产生条件，此条件通过在可调谐的窄带激光和宽带激光间的拍频实验得到证实。

| Abstract: | We have studied the spectral resolution of the time-delayed laser-induced double gratings used for measuring the frequency difference between two lights. The condition for the occurence of the FWM signal modulation is established when the pump beams have Gaussian lineshape, which has been verified experimentally through the study of beating between a tunable narrow-band laser beam and a broadband laser beam. |

| Keywords: | laser-induced grating time-delay four-wave mixing. |
