  • Patent number: 4807244
    Abstract: There are provided chemical lasers which provide pulsed radiation in the visible or near visible (denoted hereafter as short-wavelength) range. The novel pulsed short-wavelength chemical lasers are operated by detonating an explosive mixture which contains fuel and lasants, the detonation resulting in electronically excited molecules. Lasing can be brought about by energy transfer within such molecules, or by energy transfer from such excited molecules to other molecules or to atoms resulting in the desired short-wavelength laser emission. The lasers can be operated at high pulse energies.

  • Patent number: 4636287
    Abstract: Method and apparatus for exciting particles in an environment in which a selected isotope, of broadened spectral absorption bandwidth, is exposed to laser radiation having a frequency bandwidth substantially narrower than the spectral width. The laser radiation is frequency swept entirely across the broadened spectral width of the absorption band of the selected isotope type particles to provide spectral matching with substantially all of these particles. A laser system is provided having the capability of sweeping a narrow spectral emission entirely across a broadened spectral absorption band.

  • Patent number: 4257013
    Abstract: Method and apparatus for achieving isotopically selective adiabatic inversion, particularly for improved isotope separation efficiency. In a preferred embodiment for practicing the invention, chirped laser radiation induces photoionization of a vapor state material in isotopically selective excitation and ionization energy steps. A frequency sweep or "chirp" is provided in the excitation laser radiation at a controlled rate and over a range of frequencies which is limited to prevent loss of selectivity in the excitation. The frequency swept radiation has a theoretical capability of producing 100% inversion of ground state particles in the vapor. The features of the invention additionally permit excitation of a material to very high energy states useful in producing high frequency, ultraviolet lasing.

  • Patent number: 4009391
    Abstract: Frequency selective means, particularly for use in uranium enrichment by laser induced isotopically selective ionization to suppress unwanted lasing of the excited uranium medium. The frequency selective means, such as filters, are placed at intervals in a column of laser illuminated uranium vapor and are transmissive to the illuminating laser frequencies but nontransmissive to frequencies at which population inversions exist in the excited uranium. The filters limit the path length and correspondingly the gain in the excited uranium to prevent high intensity lasing by the uranium itself.
