摘　　要：提出一种基于光克尔门空间扫描的单次激光信噪比测量方法.在该方法中,门光和探测光在光克尔介质中正交传输,通过光克尔门对探测光的空间扫描实现激光信噪比测量.采用该测量方法进行了单次激光信噪比测量的实验研究,测得时间窗口和分辨率分别为88.2ps、2.7ps.由于取样门是由光克尔效应来控制,因此该激光信噪比测量方法对于待测激光的波长没有限制.A measurement method of signal-noise ratio for the single shot laser based on space scanning of optical Kerr gate was presented. In this method, the gate light and probe light transmit orthogonally in optical Kerr medium, the measurement of signal-noise ratio for the single shot laser was achieved by using an optical Kerr gate to make a space scanning for the probe light. With this approach, a single shot laser signal-noise ratio measurement was realized experimentally with a temporal window of 88.2 ps and a resolution of 2.7 ps. This method has no limitation on spectral range because of the gate is controlled by optical Kerr effect.
