From: Multi-mW, few-cycle mid-infrared continuum spanning from 500 to 2250 cm−1
MIR spectrum and beam profile. The MIR spectrum (red line) together with the noise floor (gray line) measured using a monochromator. The MIR spectrum extends from 500 cm−1 to 2250 cm−1 (−30 dB), corresponding to the wavelength range from 4.5 to 20 μm. Inset: the beam profile measured using a Pyrocam beam profiler.
