Stimulated Raman scattering microscopy by Nyquist modulation of a two-branch ultrafast fiber source — •Peter Fimpel, Claudius Riek, Peyman Zirak, Christoph Kölbl, Alfred Leitenstorfer, Daniele Brida, and Andreas Zumbusch — Universität Konstanz

A highly stable setup for stimulated Raman scattering (SRS) microscopy[1] is presented. It is based on a two-branch femtosecond 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. [1] C. Riek et al., Opt. Lett. 41, 3731 (2016)
