Robust hollow-fiber-pigtailed 930 nm femtosecond Nd:fiber laser for volumetric two-photon imaging.


PMID 29041577

Abstract

We demonstrate a robust high power 930 nm femtosecond Nd:fiber laser system with hollow-core photonic bandgap fiber (HC-PBGF) as the output delivery, which can be easily integrated into compact two-photon microscopy system for bio-imaging. The whole laser system can deliver up to 17.4 nJ, 220-fs pulses at 930 nm with repetition rate of 46 MHz. In this paper, this laser was demonstrated as the light source for volumetric imaging of zebrafish blood vessel.
