Abstract

1,073,503. Lasers. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 29, 1965 [April 1, 1964], No. 13248/65. Heading H1C. [Also in Division G2] Intersecting light beams are used to indicate in advance the eventual focal point of a convergent laser beam. As shown, light from a common light source 51 is conveyed through light conductors 48, 49, 50, to projectors 31, 32, 33 which are rigid with optical output means 11 of a laser 2. Preferably, the light beams are distinguishable as by being of different colours or cross-sectional shapes. A retractable mirror 66 enables the laser beam to be deflected through a flexible light conductor 67 for use with portable apparatus, Fig. 14 (not shown). In various modifications, each projector may have its own source, Figs. 1, 7 and 9 (not shown), and may deliver a parallel, Fig. 2 (not shown), or convergent, Fig. 3 (not shown), light beam; the laser itself may be part of the rigid structure and the laser beam may be reflected off spherical (25) and parabolic (26) mirrors, Fig. 8 (not shown). A television camera 63 and receiver 65 may be included. The invention is useful in microwelding, microboring, medicine and biology. The focal point of the laser beam may be a predetermined depth above or below the surface of the object treated.
