Paper Abstract

We report on a fiber laser setup optimized to generate and propagate high energy solitons with megawatt peak power around 1700 nm. Picosecond pulses from a chirped-pulse amplifier system at 1560 nm trigger the formation of sub-100 fs solitons with approximately 70 nJ energy in an all-solid photonic bandgap Bragg fiber with ultra-large mode area. Upon propagation in the same fiber the soliton self-frequency shift effect allows for tuning the central wavelength up to 1680 nm in a 1.5 m long piece of fiber. This work paves the way to miniaturized endomicroscopes in the biologically relevant window around 1700 nm and, thanks to the 20-cm critical bend radius of the delivery fiber, opens the way to deep in vivo imaging of freely moving animals.
