摘要： In a solid-state laser resonator (4) capable of outputting a high power linearly polarized laser beam (7), a laser beam subjected to the birefringence in the laser resonator (4) is effected to minimize a component of the laser beam which is orthogonal to the direction of polarization definable by a Brewster plate (8, 9) upon traversing a quarter-wave plate (11, 12). The linear polarization output distribution of the laser beam is thus made uniform. With this, the emission efficiency and the output power of a linearly polarized laser beam are much improved.

摘要： Disclosed is a vacuum switching apparatus for automatically performing a series of braking and disconnecting operations, thereby improving the usability and simplifying the operating mechanism. In a vacuum bulb of the vacuum switching apparatus, a movable electrode 2 is sequentially moved between a closing position Y1, an opening position Y2 and a disconnecting position Y3. After the movable electrode 2 passes through the opening position Y2 located between the closing position Y1 and the disconnecting position Y3, the between-electrode opening speed of the movable electrode 2 is reduced. With this configuration, it is possible to move the movable electrode 2 from the closing position Y1 to the disconnecting position Y3 without lowering the braking performance, and hence automatically to perform a series of the braking and disconnecting operations.

摘要： A light (30) beam including a random polarization and radiated from a light source, such as laser oscillator (6) is separated into P wave polarization light beam and S wave polarization light beam by a beam splitter 33. After modulated by image information representative of characters to be printed, both the P and S wave polarization beams are merged and the resultant light beam is projected on the surface of a workpiece for marking a pattern.
