METHOD FOR CONTROLLING GENERATION AND RADIATION DENSITY SHAPING SPECTRUM OF GEOTECHNOLOGICAL LASER BUILT AROUND MAGNETO-ACOUSTIC SPACE-TIME MODULATOR AND CONTROLLED-GENERATION SPECTRUM GEOTECHNOLOGICAL LASER Russian patent published in 2006 - IPC H01S3/10 

FIELD: laser engineering; destruction and directive change of mountain rock properties.

SUBSTANCE: proposed method includes formation of radiation density distribution over desired generation spectrum by pumping active medium with aid of laser. On one end pressure and acoustic radiation frequency are shaped within desired variation range of magnitude and direction. On other end directive magnetic field is acted upon synchronously with reflecting resonators. The latter periodically convey reflected beam to pumping chambers for enhancing energy density and power of laser beam; Geotechnological laser has pumping device, resonators, dispersion device, and magneto-acoustic space-time modulators. Dispersion devices are made in the form of rotary sound converter units with radiators. Radiation beam amplifying concentrators are coupled with pumping chambers; generation unit is provided with additional pumping chambers. Pumping chambers are mounted in two modules filled with active media. The latter are arranged in direction of optical axes perpendicular to direction of radiation beam linear dispersion. Laser heads of each module are relatively offset in vertical plane. Shielding reflectors are coupled with radiation beam amplifying concentrators.

EFFECT: ability of forming desired energy density, power, and beam intensity for destruction, synthesis, and directed change of mountain rock properties.
