An Ultrabroadband, Energetic, Tunable Fiber Source for Nonlinear Imaging and Spectroscopy
New generations of laser sources, with high pulse energy, wide continuous tunable range, and a compact form, are in high demand to advance two-photon and three-photon microscopy to its full potential for deep-tissue imaging. Multimode fibers have emerged as an early-stage but promising candidate. Effective control of nonlinear processes at high power levels in multimode fibers (MMFs) would unlock new possibilities for diverse applications including high-power fiber lasers, which potentially address the aforementioned need. This talk will discuss our recently developed approach that exploits the spatial and temporal degrees of control of nonlinear effects in step-index MMFs using a 3D-printed programmable fiber piano. By leveraging the rich spatiotemporal degrees of freedom and the high spectral brilliance in SI MMF, We have achieved broadband high-peak-power spanning nm, resulting from combined spectral energy reallocation and temporal shortening uniquely enabled by the fiber shaper. Its potential as a nonlinear imaging source is further demonstrated by applying the MMF source to multiphoton microscopy, where multi-fold signal enhancement is achieved for label-free tissue imaging with adaptive optimization.
