Abstract

Infrared supercontinua spanning the range 3–14 μm were observed when an intense pulse generated from a CO2 laser was passed into GaAs, AgBr, ZnSe, and CdS crystals. These supercontinua have been qualitatively compared with theoretical predictions.

Supercontinuum spectra from a 6-cm-long Cr-doped GaAs crystal. ○ 2.5-psec pulse duration, full power; △, 2.5-psec duration, half power; ●, 8-psec pulse duration, full power; +, 8-psec pulse duration, half power; ▽, 8-psec pulse duration, quarter power. SRS, stimulated Raman scattering; Is, signal energy; IL, relative input laser energy; C, correction factor for the spectral sensitivity variation of filters, grating, and detectors. The solid lines are guides. The dashed lines are the noise levels. The laser pulse displayed was obtained when sample was removed and attenuated roughly 500 times. Each data point corresponds to an average of at least three shots. The standard deviation of each point is ±10%. The lower excitation laser power used in the Stokes side was due to the extra filter added in the experiment to block out noise. The 3-μm signal could be a combination of the harmonic frequency broadening, the primary continuum extension, and other mixing processes.
