Method and device for detecting the threshold of generation of a non-visible laser beam, wherein a dark colored film, enclosed in a transparent container, is placed in the path of the laser beam to cause the dark film to burn when the laser beam impinges thereon and wherein the transparent container prevents the vaporized film particles from the area impinged upon by the laser beam from escaping into the atmosphere.
