摘要： Disclosed is a gas laser utilizing radio frequency discharge excitation in the area of sonic or supersonic/subsonic transfer gas flow. The laser uses various types of gases and mixtures of gases as the active medium and provides for RF or UV pre-ionization of the gaseous medium before using radio frequency discharge excitation. The gas is supplied into a receiver (3a), and has downstream therefrom a supersonic nozzle (1) for acceleration of the active gaseous flow to high subsonic or supersonic speeds in order to provide intensive dynamic cooling of the active gas medium. The gas is excited using radio frequency discharge excitation in the critical area (1b) of the supersonic nozzle or downstream therefrom. The radio frequency discharge and excitation can also occur within the optical resonator region (23) which is located within the supersonic area of the nozzle. The present invention provides compact, efficient and super-powerful continuous, quasi-continuous and pulse laser systems with wavelengths from 2.03 mkm to 10.6 mkm with a high quality output beam. The present laser device may be utilized in scientific, commercial, aerospace and free space applications.

摘要： A method for cold-forming a nozzle (10) for a laser includes placing a slug or tube (34) of oxygen-free copper into a die (36). A mandrel (40) is forced into the copper slug or tube. The resultant compressive force causes the copper to cold flow around the mandrel and the die to define an inner shape (38) and an outer dimension (14) of the part.

摘要： In a gas laser device according to this invention, a gas inlet (5) having an electrode (8) protrudes within each of expanded portions (l5) protruding on the side, where the gas inlet is disposed, of the principal portion of the discharge tube (l). Gas medium (7) ejected from the gas inlet (5) in the principal portion of a discharge tube (l) collides with the inner surface of the principal portion of a discharge tube (l), while forming a flame (20) extending along the ejected gas medium from the electrode (8) and is divided into two partial flows (7A, 7B). One (7B) of them flows along the wall of the expanded portion (l5); collides with the gas inlet (5); and is divided further into two partial flows. Therefore it does not collide with the gas medium (7) within the gas inlet (5). Consequently the gas medium (7) and the flame fluctuate hardly and are stabilized. In this way it is possible to stabilize the laser output.
