    Abstract: A device for producing or amplifying coherent radiation includes a semiconductor device such as a laser. By means of electrons of high energy produced by a semiconductor cathode of the device, population inversion is obtained in an active layer of the laser structure. In this manner, laser action is obtained, which offers advantages, especially with II-VI materials which emit radiation of a wavelength shorter than the usual III-V materials, and which do not permit the desired population inversion to be obtained in the same manner as in III-V materials, by means of current injection across a pn junction. The semiconductor cathode and the laser structure can be arranged in mutual separation in a vacuum tube or be realized in one semiconductor body. The short-wave laser is especially advantageous for CD,DOR and VLP applications.

    Abstract: A piezoelectric igniter with a manually operable striking mechanism which comprises a hammer, a piezoelectric transducer, and a energy storing or compression spring acting on said hammer and operated by an actuating member. The hammer is held in its rest position by a release device adapted to release the hammer when a definite compressive force is exerted on the same. A bounce plate is mounted at the end of the transducer facing the hammer and a return spring is provided between said bounce plate and the hammer. The transducer has a lateral clearance to a housing which receives all component parts.
