RADIATION GENERATING UNIT OF MULTICHANNEL LASER Russian patent published in 1998 - IPC

FIELD: laser technology. SUBSTANCE: case of laser has cylindrical form and is manufactured from electric insulation material. Gaseous-discharge tubes are placed in package in one row in diagonal plane of case equidistantly one from another, separators are joined by longitudinal fastening tubes made from same material as gaseous-discharge tubes. There are two symmetric closed circuits on both sides of package of gaseous-discharge tubes, their external branches form cylindrical surface concentric on case and their internal branches are located in planes parallel to plane of package of gaseous-discharge tubes. Windows in separators used for flow of cooling fluid are situated inside one of circuits formed by fastening tubes. Two longitudinal buses to feed high alternating voltage are installed into fastening tubes, are joined to separators and brought outside case. Pulling rods of optical resonator are positioned outside case. Sealed space to pump through cooling fluid is formed by internal walls of case and external walls of tubes. Other versions of unit are also possible. EFFECT: enhanced functional reliability. 3 cl, 6 dwg
