摘要： A laser system wherein, in order that a high-output and high-quality single mode of a cross sectional area larger than the beam diameter determined by the construction of a resonator can be obtained stably, although this has heretofore been impossible, there is used a coupling mirror provided with a partial reflection film and an antireflecting film, a laser beam mode is selected using the partial reflection film, a phase difference between laser beam portions caused by a difference in construction between the partial reflection film and the antireflecting film is compensated using a phase difference compensating apparatus, and there is formed an aperture whose diameter is set to a value of not larger than four times the diameter of the partial reflection film.

摘要： A laser oscillator has a casing 10. A cooling medium is supplied from an inlet port 134 to a heat exchanger 8 via a pipe 35, and discharged form it via a pipe 37 and an outlet port 136. The ports 134 and 136 are symmetrically positioned relative to a center line of the casing when seen from upward. An inlet port 340 and an outlet port 342 have a similar positional relation ship thereto.

摘要： A laser oscillator comprising a laser resonator having a plurality of mirrors for directing the laser energy from source to exit apertures, the mirrors being constructed and mounted adjustably for reducing parasitic oscillations. The mirrors are mounted in adjusting members that have channels therein for coolant and are provided with heat insulating members that minimize heat gradients and unwanted heat transfers that may result in the distortion of the reflecting surfaces. In addition, the mirrors are angled so that light paths are defined that present a Z-shaped turning pattern. Apertures proximate to the mirrors through which the light beams are directed are offset from a common plane so that a reflective surface is not within the aperture of the opposing reflective surface. One or more of the apertures can be so offset to reduce the possibility of parasitic oscillations. Further, the reflectors can be angled and the apertures sized so as to eliminate parasitic oscillations.
