Paper Abstract

We present high-speed multicolor coherent Raman imaging enabled by a novel all-fiber light source. A high tuning speed of < 5 ms per arbitrary wavelength step (700 - 3530 wavenumbers) allows to switch the wavelength in a frame-by-frame manner when imaging with up to 100 frames/s. The pump (up to 200 mW) and Stokes pulses (> 400 mW) exhibit equal durations of 7 ps. The compact and environmentally stable system is predestined for fast multicolor assessments of medical or rapidly evolving samples with high chemical specificity.
