PHOTODISSOCIATION LASER, METHOD AND DEVICE FOR CONTROLLING LASING SYSTEM BUILT AROUND IT Russian patent published in 2004 - IPC

FIELD: quantum physics; laser engineering.

SUBSTANCE: proposed photodissociation laser that can be used, for instance, to manufacture lasing systems for producing high-density electromagnetic radiation beams has working chamber holding explosive charge in the form of truncated cone with conical cavity coaxial to outer surface of this truncated cone and converging from its larger base. Cone angle of cavity is smaller than that of truncated-cone side surface; explosive charge firing devices are uniformly distributed over side end of truncated cone. Lasing system built around two photodissociation lasers coupled through their like-polarity butt-ends and provided with remote-control receivers on their loose ends for firing explosive charge is controlled by collimation of specially shaped parallel electromagnetic radiation beam, division of collimated beam into two equal-strength beams, conversion of beams obtained into parallel circular-section beams, followed by their opposing and simultaneous supply to remote-control receivers of photodissociation lasers for firing explosive charges. Lasing system control device has two photodissociation lasers coupled through their like-polarity butt-ends and provided with remote-control receivers disposed over periphery on loose ends of lasers, re-reflection mirror, radiation output mirror mounted on optical axis opposite loose ends of photodissociation lasers, and parallel electromagnetic beam source, as well as electromagnetic radiation beam expander, beam-splitting prism, two transfer optics units, and two axicons each made in the form of reflecting-surface internal and external cones .

EFFECT: enhanced beam radiation density, facilitated procedure, reduced cost of lasing system.
