摘要： A flowing gas ''''mixing'''' laser of the type which introduces a lasing gas into the laser chamber in proximity with the optical cavity, and provides excited energizing gas to the laser chamber separately, uses the cooling capacity of the liquefied lasing gas to improve the overall operation of the system. In one embodiment, the source of liquefied lasing gas is utilized as a coolant in a heat exchanger connected between the gas laser outflow and the inlet to the compressor used to cause gaseous flow through the laser. The compressor inlet temperature is reduced, thus permitting an increase in the capacity of the compressor and a reduction in the power of the prime mover which operates the compressor. In one variation of this embodiment, the lasing gas, from a liquefied source thereof is passed through the compressor inlet gas heat exchanger and is also utilized to cool the jacket of the laser chamber. In another variation of this embodiment, the lasing gas that is utilized as a coolant in a heat exchanger is vented to atmosphere, and the source of liquefied lasing gas also supplies the laser independently of the heat exchanger. In still another variation of this embodiment, a water cooled heat exchanger is used to precool the laser effluent before passing through the laser gas cooled heat exchanger. In another embodiment of the invention, the source of liquefied lasing gas is introduced in proximity with the laser chamber as a lasing gas and is separately used in heat exchangers to cool the inlet air and the gases leaving the laser chamber, and then vented to ambient. In each embodiment, the outflow of the compressor is vented to ambient, and the prime mover also powers an electric generator to operate a power supply that produces high-voltage DC current for a DC electric discharge plasma excitation means.

摘要： An active gas based on CO.sub.2 penetrates under pressure into a discharge chamber (20) via injection orifices (10) formed through the upstream face of said chamber. These orifices leave considerable solid portions (22) about themselves in said face such that the gas forms jets which diverge up to an outlet grid (12) constituting a common anode. Cathodes (8) are individually powered by a block (14) and give rise to discharges which are widened on the edges of said jets by large-amplitude gas recirculation currents, thereby increasing the electrical power injected. The invention is particularly applicable to power lasers.

摘要： An axial flow gas transport laser comprising an excitation tube through which gas flows along an axis of the tube, an inlet arrangement to feed gas towards the excitation tube and an outlet arrangement to discharge gas from the excitation tube. At least one of the inlet and outlet arrangements comprises a circumferential opening arrangement evenly distributed along the periphery of the excitation tube, substantially in a cross-section plane of the tube. A gas flow channel arrangement to the opening arrangement is directed at least substantially in the direction of the excitation tube axis and into the excitation tube at the opening arrangement for preventing wide-areal turbulances of the gas flowing in the excitation tube.

摘要： A high pressure, high power, continuous wave electro-dynamic laser having one of the electrodes (preferably the cathode) made of a porous conductive surface and a backing material capable of broad band acoustic absorption. Such an arrangement effectively absorbs acoustic disturbances which arises primarily from a linear instability within the resonant cavity of the electro-dynamic laser and thereby substantially reduces output flux modulations within the resonant cavity.
