The present invention overcomes the disadvantages and limitations of the prior art by providing a Stokes injected Raman waveguide amplifier. The device uses an external Stokes signal injected in a capillary waveguide amplifier which Raman scatters CO/sub 2/ laser radiation by rotational states of a diatomic molecule such as H/sub 2/, D/sub 2/, HD, HT, DT or T/sub 2/. The Stokes injection signal reduces the reguired field strength of the CO/sub 2/ laser radiation and eliminates the necessity for spontaneous generation of Stokes radiation within the capillary amplifier. It is an object of the invention to provide a Stokes injected Raman capillary waveguide amplifier. It is also an object of the invention to provide a Stokes injected Raman capillary waveguide regenerative amplifier. Another object of the invention is to provide a Stakes injected Raman capillary waveguide amplifier having high output powers.
