PCT No. PCT/FR93/00423 Sec. 371 Date Dec. 10, 1993 Sec. 102(e) Date Dec. 10, 1993 PCT Filed Apr. 30, 1992 PCT Pub. No. WO93/22095 PCT Pub. Date Nov. 11, 1993.A safety device for use with a laser beam (5) passing from a source (1) along a given optical path which optionally includes mirrors (M1-M5), in conjunction with a beam control signal processing network. The processing network includes at least one removable signal blocking element (10, 10') located on the optical path and at least partially consisting of a signal conductor (16, 18, 19) surrounding said beam (5) for co-operating therewith in order to cut off the signal instantaneously and block the beam should any deflection occur.
