METHOD OF CLEANING SURFACES OF MATERIALS, DEVICE USED Russian patent published in 1995 - IPC

FIELD: cleaning-surfaces technique. SUBSTANCE: peak power of laser source of light is regulated within 17 and 50 Mwt, pulse duration being between 10 and 30 m.per sec. Diameter of the beam of light of the laser source on the surface to be cleaned has to be chosen provided that the density of peak power on the area be in the range of 22 and 53 Mwt per sq. cm. The device under review has a laser, block of power supply, casing, laser beams, optic fiber, optic means for combining laser beams, optic means for regulating diameters. EFFECT: higher efficiency and reliability. 6 cl, 2 cl, 3 dwg
