We introduce a novel configuration for broadband, time-resolved CARS spectroscopy/microscopy in which pump, Stokes and probe pulses are all derived from a single femtosecond Yb:KYW laser. The 1-MHz repetition rate of the system allows very intense CARS signals to be obtained over short acquisition times, while a delayed probe pulse ensures an efficient non-resonant background suppression.
我们介绍了一种用于宽带、时间分辨相干反斯托克斯拉曼散射（CARS）光谱学/显微镜的新型配置，其中泵浦光、斯托克斯光和探测光脉冲均来自单个飞秒镱：钇钽酸钾（Yb:KYW）激光器。该系统1MHz的重复频率使得在短采集时间内就能获得非常强的CARS信号，同时延迟的探测光脉冲可有效抑制非共振背景。
