Abstract
We demonstrate a novel multimodal nonlinear spectral microscopy based on a femtosecond Cr:forsterite laser at 1230 nm. By acquiring the whole nonlinea r spectrum in the visible and near-NIR region, this novel technique allows a combination of different imaging modalities, including second-harmonic ge neration, third-harmonic generation, and multiple-photon fluorescence. Comb ined with the selected excitation wavelength, which is located in the IR tr ansparency window, this microscopic technique can provide high penetration depth with reduced damage and is ideal for studying living cells.
