1. A mid-infrared broadband laser comprising:
a femtosecond laser configured to generate a near-infrared light;
a nonlinear waveguide configured for anomalous dispersion, and broadening and/or shifting a spectrum of the light from the femtosecond laser, and with mid-infrared transmission at wavelengths longer than 2 μm, such that self-compression and higher order soliton propagation occur for a portion of the light spectrum above 2 μm; and
a nonlinear medium configured to generate a broadband light by mixing spectral components of the output from the nonlinear waveguide.
