We present high-speed multicolor stimulated Raman scattering imaging (SRS) enabled by an all-fiber light source. With a relative intensity noise level of -157 dBc above 10 MHz the light source is shot-noise limited up to a detector current of 0.75 mA. Compared to other fiber-based light sources optimized for SRS, the presented system is tunable in under 5 ms per arbitrary step between 700 and 3530 wavenumbers. The compact and environmentally stable system is predestined for fast multicolor assessments of medical or rapidly evolving samples with high chemical specificity.
