Stimulated Raman scattering (SRS) microscopy has emerged as a valuable tool with manifold biomedical applications. Due to the physical limits of Raman cross section, enhancing chemical information bandwidths comes at the price of decreasing the signal-to-noise ratio (SNR). One appealing approach to combat the physical limits is denoising. In this work, we propose a self-supervised Noise2Noise 3D Unet denoiser for three-dimensional SRS imaging. To demonstrate the limit-breaking capability, we denoised three types of three-dimensional SRS datasets, including hyperspectral, volumetric, and longitudinal, under extreme experimental conditions with low SNR. Our results highlight the potential for boosting the physical limits by integration of instrumentation and computation.
