Abstract
A safety system for a laser-beam utilizing facility incorporates a safety enclosure (24) and an infra-red monitoring system (32) for detecting the development of hot spots at internal surfaces of the enclosure walls (24) and ceiling (26) which may occur as a result of stray laser radiation impinging on such surfaces. The development of a hot spot leads to shutting off the laser source (10) or interruption of the beam by means of a shutter (22).
