High-contrast Multiphoton Microscopy based on Shaper-Assisted Collinear SPIDER Pulse Compression — •Bernhard von Vacano, Tiago Buckup, and Marcus Motzkus — Physikalische Chemie, Philipps-Universität Marburg, D-35032 Marburg, Germany

Broadband femtosecond pulses can be characterized and shaped in situ in microscopy with a simplified SPIDER scheme: the use of a femtosecond pulse shaper eliminates the need of an interferometer setup and allows characterization, compression and tailoring of complex pulses at the same time. Here, we present the design considerations and details of the experimental implementation of this shaper-assisted collinear (SAC-) SPIDER^[1], as well as the application to multiphoton microscopic imaging. The technique is compared with independent cross-frequency resolved optical gating (XFROG) measurements. The simplicity and versatility of SAC-SPIDER make it very useful for next-generation nonlinear microscopy with broadband femtosecond laser pulses.
