The patent discloses a system for generating a continuous wave CW chemically pumped lasing action. A continuous radiation output is achieved by a technique which involves generation of a high speed jet containing a reactant and an inert diluent. A second reactant is diffused into the high speed jet. The chemical reaction between these reactants creates, directly, a vibrationally excited gaseous product with the requisite population inversion and lifetime needed for lasing. The vibrationally excited product gas is created within, or flows into, an optical cavity whose axis is transverse to the flow. Lasing is made to occur within the optical cavity. After lasing, the product gas is quickly convected out of the optical cavity by the high speed jet.
