TRANSVERSE-FLOW ELECTROOPTICAL LASER UNIT

摘要

FIELD: quantum electronics. SUBSTANCE: fast-flow gas laser unit has gas- discharge chamber stretched along gas flow and provided with multisection set of electrodes with sections arranged in parallel to gas flow and optical resonator which is stable and unstable in two relatively perpendicular planes crossing optical axis transverse to gas flow; instability plane of optical resonator is perpendicular to gas flow. Optical resonator may have even number of passages about even number of sets of electrodes; passage-to-passage transmission of laser beam is effected by means of mirror units turning about gas flow. EFFECT: improved power and quality of laser beam. 3 cl, 5 dwg
