Estimating the term…
A high-power gas laser pumped by an intense, pulsed, space charge-and current-neutralized ion beam. A high-pressure gas in the laser cavity is ionized by an ion beam. Atomic processes occur which result in a population inversion for the excited states of the gas. Coherent radiation is then emitted by the excited gas atoms in the inverted state. The light is amplified as it traverses the gas. Multiple traversal can be obtained by using an optical cavity comprising mirrors which reflect the light into the excited gas so that the light can be further amplified with each pass through the cavity. Extraction of light energy is done by using a partially transmitting mirror as part of the optical cavity.
In a high-pressure gas laser system comprising a high pressure gas cell filled with one or more laser gases at a total pressure greater than 0.1 atmosphere but not more than 10 atmospheres, said system including Brewster angle windows which are transparent to the laser output at each end of the gas cell in optical alignment about the optical axis of said gas cell and which provide a means for extraction of laser radiation, the improvement comprising:
An ion-beam-excitable gas laser which comprises:
A method of exciting a gas mixture in a chamber of a pulsed gas laser which comprises:
