摘要： Apparatus and methods relating to a gas flow laser are disclosed herein. The gas flow laser includes an eccentrically aligned inner casing within a cylindrical or oval outer shell thereby creating a narrow gas flow path in which the speed of the gas flow may approach sonic or supersonic speeds. An optical resonator is within the narrow gas flow path, and one or more diffusers are located downstream of the optical resonator to improve operating efficiency of the gas flow laser.

摘要： Disclosed is a gas laser utilizing high 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 pre-ionization of the gaseous medium before using high frequency discharge excitation. The gas is supplied into a receiver, and has downstream therefrom a supersonic nozzle 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 high frequency discharge excitation in the critical area of the supersonic nozzle or downstream therefrom. The high frequency discharge and excitation can also occur within the optical resonator region 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 0.3 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： Disclosed is a gas laser utilizing radio frequency 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 using radio frequency excitation. The gas is supplied into a supersonic nozzle for acceleration of the active gaseous flow to supersonic or deceleration to high subsonic speeds in order to provide intensive dynamic cooling of the active gas medium. The gas is excited using radio frequency excitation in the critical area of the supersonic nozzle or downstream therefrom. The radio frequency action and excitation can also occur within the optical resonator region which is located within the supersonic area of the nozzle.

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, and has downstream therefrom a supersonic nozzle 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 of the supersonic nozzle or downstream therefrom. The radio frequency discharge and excitation can also occur within the optical resonator region which is located within the supersonic area of the nozzle.
