摘要： A continuous liquid chemical injector utilizing a back pressure of inert gas to control the amount of mass flow rate of a liquid chemical into the volume of interest such as the plenum of a gas dynamic laser or a combustion initiated chemical laser. The mass flow rates are continuous and can be varied with the variations being programmed when desired. The device permits no release or leakage of the chemicals to the atmosphere or the surroundings.

摘要： A laser having a gas generating section that delivers a flow of hot nitrogen gas (N2) to a nozzle. The N2 is expanded through the nozzle to achieve supersonic flow of the N2. The nozzle includes injection ports positioned so as to inject cold carbon dioxide gas (CO2) into the N2 flow at a point in the nozzle where flow is supersonic, just downstream of the throat. The injection of a cold gas enhances population inversion in the cold gas. Thorough mixing of the hot and cold gases occurs prior to exit of the gases from the nozzle. The gases exhaust from the nozzle into a lasing chamber wherein laser energy is extracted from the flow.
摘要翻译：一种激光器，具有将热氮气（N2）流向喷嘴的气体发生部。 N2通过喷嘴膨胀以实现N2的超音速流动。该喷嘴包括喷射口，该喷射口定位成将冷二氧化碳气体（CO 2）喷射到喷嘴中的喷嘴中，其中流动是超音速的，恰好在喉部的下游。冷气的注入增强了冷气中的人口倒数。在从喷嘴排出气体之前，会发生热和冷气体的彻底混合。气体从喷嘴排出到激光室，其中从流中提取激光能量。

摘要： A laser having a gas generating section that delivers a flow of high pressure high temperature gas which contains a large concentration of active fluorine atoms (F) to a nozzle. This gas is expanded through a nozzle to achieve low pressure low temperature supersonic flow which still contains the large concentration of the active atoms. The nozzle includes one set of injection ports positioned so as to inject cold carbon dioxide gas (CO2) into the flow at a point in the nozzle where the flow is supersonic, just downstream of the throat; and another set positioned so as to inject deuterium (D2) into the flow after the CO2 has mixed with the fluorine containing flow, just at the nozzle exit plane. All gases exhaust from the nozzle into a lasing chamber wherein the energy of F + D2 reaction which initially appears as vibrational energy in the product DF molecule is transferred in collisions to the CO2 molecule. Thus producing a total inversion in the CO2 which allows the energy to be extracted as a laser beam from the flow.
摘要翻译：一种具有气体发生部分的激光器，其向喷嘴输送含有大量活性氟原子（F）的高压高温气体流。该气体通过喷嘴膨胀以实现仍然含有大量活性原子的低压低温超音速流。所述喷嘴包括一组注射口，所述注入口定位成将冷二氧化碳气体（CO 2）注入所述喷嘴中的流动超音速的点处，恰好在所述喉部的下游; 另一组定位成在CO 2与含氟流体混合之后恰好在喷嘴出口平面处，将氘（D2）注入流中。所有气体从喷嘴排出到激光室，其中最初在产物DF分子中作为振动能产生的F + D2反应的能量以碰撞方式转移到CO 2分子。因此在CO 2中产生总反转，其允许能量从流中作为激光束提取。
