Introduction

Compact, alignment-free and all-fiber picosecond laser source for CARS microscopy delivering synchronized pump and Stokes pulses from a single fiber end. This air-cooled and turn-key CARS laser source has a great benefit for the user as the fiber delivery eliminates alignment of the spatial and temporal pulse overlap.

High-quality and high-speed microscopic multimodal nonlinear imaging is possible by e.g. simultaneously probing the CARS CH-vibrational-levels of lipids around 2850 cm-1, the second harmonic generation (SHG) and the two-photon excited fluorescence (TPEF) signals.
