Abstract

We propose a versatile pulse shaper using a 2D spatial light modulator to perform simultaneous and independent control of the spectral amplitude and phase of a fiber-based supercontinuum source. Different spectral optimizations will be demonstrated in a multimodal optical imaging system, combining optical coherence tomography (OCT), multiphoton microscopy (MPM), and nonlinear Raman imaging. This custom pulse shaper enables fast wavelength-tunable excitation for Raman spectroscopy with high spectral resolution. Single beam simultaneous MPM and OCT can also be enabled by compressing a selected multiphoton excitation band while chirping the whole spectrum for ultra-high-resolution OCT.
