Abstract

A super-continuum system including: a fiber laser (110) configured to output a pulse having a center wavelength; a first nonlinear waveguide (120) configured to shift the wavelength of the pulse from the fiber laser; a first fiber amplifier (130) of at least one stage configured to amplify the output from the first nonlinear waveguide; and a second nonlinear waveguide (140) configured to spectrally broaden the output from the first fiber amplifier.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 924,629, filed January 7, 2014, the contents of which are incorporated herein by reference. technical field [0003] The invention relates to the field of supercontinuum systems, in particular to a mid-infrared supercontinuum generator and system using a tunable femtosecond oscillator. Background technique [0004] Broadband light sources in the mid-infrared (MIR) range (2um to 10um) are used in applications such as remote sensing, infrared counter metrology, medical diagnostics and spectroscopy. Although incoherent broadband MIR sources have been available for many years and have been applied in spectroscopy, these sources have limited power spectral density and poor beam quality. Coherent broadband sources based on nonlinear spectral broadening, known as supercontinuum sources, are studied in the visible and near-infrared (NIR) range of ...
