OUTPUT WINDOW Russian patent published in 1996 - IPC

FIELD: output windows of high-power wide-aperture gas lasers with an unstable resonator, whose outgoing mirror is secured on the straightway optical member. SUBSTANCE: output window has a mirror and a straightway optical member hermetically secured in whose opening in the casing that also has an opening. Secured on the casing is a cylinder, whose diameter is less than the diameter of the mirror with adjusting screws installed on it. Positioned in the casing opening is the carrying rod, whose front part is connected to the mirror, and the rear part is engageable with the adjusting screws, and hermetically connected to the bellows, which in turn is hermetically connected to the casing. Between the mirror and joint to the bellows the carrying rod is hinge-joined to the casing. The output window provides for an output of a high-energy radiation in the form of a solid ring from the laser medium, around the outgoing mirror without getting of the members of adjustment, attachment and cooling of the mirror in the laser beam. Heat from the mirror is removed into the atmosphere, and the mirror can be adjusted relative to the straightway optical member. EFFECT: enhanced efficiency. 2 cl, 2 dwg
