High energy supercontinuum sources using tapered photonic crystal fibers for multispectral photoacoustic microscopy

Abstract

© 2016 Society of Photo-Optical Instrumentation Engineers (SPIE). We demonstrate a record bandwidth high energy supercontinuum source suitable for multispectral photoacoustic microscopy. The source has more than 150 nJ/10 nm bandwidth over a spectral range of 500 to 1600 nm. This performance is achieved using a carefully designed fiber taper with large-core input for improved power handling and small-core output that provides the desired spectral range of the supercontinuum source.
