Abstract
An infra-red emission source, tunable down to 16 $\mu$ m is produced by a hydrogen Stokes-shifted dye laser. The peak power measured at 16 $\mu m$ is about 50 kW in 2 ns within a one millimeter diameter parallel beam. The corresponding light flux of the order of 5 MW $cm^{-2}$ could allow vibrational excitation of molecules absorbing down to 16 $\mu$m. Simultaneous emissions from the laser and from the previous Stokes bands are available at: 0.76, 1.12, 2.09 $\mu m$ with respective peak powers of 550, 50, and 20 MW. Spectral widths of $0.8 cm^{-1}$ for the dye laser and of 7.10$^{-2}$ $cm^{-1}$ for the Stokes bands are obtained.
