Ultrafast fibre laser enables supercontinuum generation

Chromacity Ltd reports that the outstanding coupling efficiency and high stability of its Model 1040 ultrafast fibre laser enable the generation of exceptionally broad and flat supercontinua in the near-infrared region (750-1300 nm).

This compact and user-friendly laser provides an ideal solution for producing a cost-effective near-infrared supercontinuum by focusing ultrashort pulses into nonlinear materials, such as photonic crystal fibres. Unlike solid-state lasers, which typically produce beams with an elliptical cross-section, the Model 1040 laser outputs from a single-mode fibre, ensuring a perfectly symmetric beam that achieves coupling efficiencies exceeding 75% into photonic crystal fibres.

A technical note from Chromacity explores the implementation of supercontinuum generation in nonlinear fibres as a cost-effective method for producing broadband near-infrared light. This light source is well-suited for applications such as spectroscopy, optical coherence tomography, and CARS spectroscopy/microscopy.
