  • Resonantly enhanced four-wave mixing
    Patent number: 4095121
    Abstract: A method and apparatus for achieving large susceptibilities and long interaction lengths in the generation of new wavelengths in the infrared spectral region. A process of resonantly enhanced four-wave mixing is employed, utilizing existing laser sources, such as the CO.sub.2 laser, to irradiate a gaseous media. The gaseous media, comprising NH.sub.3, CH.sub.3 F, D.sub.2, HCl, HF, CO, and H.sub.2 or some combination thereof, are of particular interest since they are capable of providing high repetition rate operation at high flux densities where crystal damage problems become a limitation.

  • Generation of coherent rotational anti-Stokes spectra
    Patent number: 4084100
    Abstract: A method and apparatus for spectroscopic gas analysis are provided. Two coherent beams of monochromatic radiation are directed through gaseous material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially the rotational frequency of a preselected constituent of the gaseous material. Radiation scattered by the gaseous material is received by a filtering mechanism adapted to transmit selectively an anti-Stokes signal generated coherently during scattering. The signal is received by a detecting mechanism which indicates the intensity thereof.

  • Continuous wave generation of coherent vibrational anti-stokes spectra
    Patent number: 4077719
    Abstract: A method and apparatus for spectroscopic material analysis are provided. Two coherent, continuous beams of monochromatic radiation are directed through a sample of material. A tuning mechanism adjusts the frequency difference between the radiation beams to equal substantially the vibrational frequency of a preselected constituent of the material. Radiation scattered by the material is received by a filtering mechanism adapted to transmit selectively an anti-Stokes signal generated coherently during scattering. The signal is received by a detecting mechanism which indicates the intensity thereof.
