LASER THERAPEUTIC INSTALLATION Russian patent published in 1997 - IPC

FIELD: medical technics. SUBSTANCE: laser installation, which may be used for treating patients carrying human immunodeficiency virus, including power-supply unit, control unit, and semiconductor laser emitter is supplemented with attachment consisting of waveguide optical emission concentrator coupled with light conductor. The concentrator constitutes a fragment of light conductor in the form of truncated cone, outer conical surface of which is covered with alternating quarter-wave dielectric layers with different refractory index values. The first layer immediately abutting upon cone surface as well as all odd layers have refractory index lower than that of cone material, whereas all even layers have higher refractory index than odd layers. EFFECT: improved structure. 2 dwg, 2 tbl
