  • Method and apparatus for optimizing coupled laser resonator performance
    Patent number: 4896324
    Abstract: A method and apparatus for frequency coupling laser resonators and optimizing the performance thereof includes a displaceable mirror for varying the cavity length of a resonator and a controller for selecting the cavity length. The apparatus includes a spectrophone which provides a feedback signal which is dependent only upon the resonator beam frequency.

  • CO.sub.2 Coupling material
    Patent number: 4426843
    Abstract: An improved energy conversion device for converting the energy carried by a laser beam to kinetic energy of a working fluid transparent to the laser radiation incorporates a seed gas having a relatively low dissociation temperature. The beam is focused to a beam spot the maximum diameter of which depends on the total power of the beam.

  • Laser photochemical separation of hydrogen isotopes
    Patent number: 4171251
    Abstract: A method of separating isotopes of hydrogen utilizing isotopically selective photodissociation of organic acid is disclosed. Specifically acetic or formic acid containing compounds of deuterated and hydrogenated acid is irradiated by radiation having a wavelength in the infrared spectrum between 9.2 to 10.8 microns to produce deuterium hydroxide and deuterium hydride respectively. Maintaining the acid at an elevated temperature significantly improves the yield of isotope separation.
