    Abstract: 1,012,344. Optical masers. WESTERN ELECTRIC CO. Inc. Sept. 27, 1962 [Oct. 3, 1961], No. 36675/62. Heading H3B. The active medium of an optical maser is formed by a thin film 13 in the form of a cylinder on a crystal 11 of lower refractive index. As shown, the thin film 11 which is only a few wavelengths thick extends to the edges 12 of the crystal 11 which is coated with mirror surfaces 14 but it is stated that the crystal 11 may extend beyond the film and be provided with cooling fins to form a more efficient heat sink. The crystal 11 may also be hollow to allow it to be cooled by air or water. The mirror surfaces 14 of the thin film do not need to be as accurate as in the case of solid laser crystals as internal reflection at the surfaces of the film 13 does not produce a large number of possible modes because of the thinness of the film 13. The crystal 11 may be sapphire and the thin film 13 may be ruby. The ruby film may be grown on a sapphire crystal or a sapphire crystal may be doped to produce a ruby film.

    Abstract: PROBLEM TO BE SOLVED: To provide a compact device having a good operability, facilitate measuring work and selectively use desired single color light by providing an electron beam generation means and a substitute means for pulse-driving electron beams produced by pulses sent from a power source device and emitting a light at an optional timing. SOLUTION: A power source device 10 is composed of a pulse generator 10a, a flyback transformer 10b and others. When an optional pulse is provided to a connection part (electrode) 10c connected to the read side of a discharge container 2, an electron gun 3 as the electron beam generation means is actuated by the pulse and then an electron beam is generated. Since excimer light emission is carried out by the electron beam generated by the pulse, a device is made compact and workability such as easy attachment to an installing position is improved. Also, since filled rare gas is replaced by a substitute means 15, a vacuum ultraviolet excimer light is used according to a work situation.
