This work aims to improve multicolor two-photon microscopy by developing a new excitation light source.
Designed a Yb-doped fiber laser with nonlinear spectral shaping in a photonic crystal fiber.
Optimized design for three spectrally isolated excitation bands at specific wavelengths.
Conducted multiplexed two-photon imaging on stained mouse tissues.
Achieved excitation bands centered at 960, 1080, and 1175 nm with high pulse energy.
Demonstrated effective imaging of astrocytes, neurons, and nuclei in complex tissues.
Showed that this approach eliminates the need for multiple laser sources.
