Abstract

In this work, we present two approaches for Broadband coherent anti-Stokes Raman spectroscopy (BCARS) imaging for biomedical research applications. The first approach is optimized for fast microscopy. The setup combines a chirped pulse amplification laser with the generation of supercontinuum generation in YAG crystal and PCF fibers. The second approach uses a fiber-based optical parametric amplifier to enable fast-tuned narrow-band pulses for fast hyperspectral multi-modal image acquisition in endoscopy settings.
