Abstract
Tunable infrared radiation was produced in the spectral range 11 μm to 23 μm by nonlinear mixing of two ruby-pumped dye lasers in proustite. A peak power of about 3 watts was observed at 19 μm. A 7o crystal angle was sufficient to achieve phase matching over the entire wavelength range. Ordinary wave absorption measurements in proustite correlate well with the observed difference frequency output, once allowance has been made for the convergence of the dye laser beams.
