摘要

A highly stable setup for stimulated Raman scattering (SRS) microscopy is presented. It is based on a two-branch femto-second Er: fiber laser operating at a 40 MHz repetition rate. One of the outputs is directly modulated at the Nyquist frequency with an integrated electro-optic modulator (EOM). This compact source combines a jitter-free pulse synchronization with a broad tunability and allows for shot-noise limited SRS detection. The performance of the SRS microscope is illustrated with measurements on samples from material science and cell biology. (C) 2016 Optical Society of America
