Abstract |
Emission of two high-power pulsed CO2-lasers with a transverse discharge at atmospheric pressure in
the active medium and the output beam aperture 100х100 mm, united by a joint unstable telescopic reso-nator, was coherently summarized under conditions of real ground-level trackon the screen surface, which
was remote from output mirror of the laser at a distance of 263 m. Output Brewster windows of laser cu-vettes were manufactured from single-crystal plates of sodium chloride which had a diameter of 300 mm.
Mirrors for resonator and optical circuit were manufactured from oxygen-free copper. Active medium - a
mixture of gases: CO2: N2: He in the ratio 1 : 2 : 3. Laser pulse duration is 5 microseconds. During the ex-periment, when summing on the screen 2-laser beams at the lowest possible convergence angle of rays, the
interference pattern was registered.
