[0025] The following non-limiting examples can enable those skilled in the art to understand the present invention more fully, but do not limit the present invention in any way.
[0026] As shown in the accompanying drawings, the present invention is based on a dual-stage injection amplification device of a high-power gas flow chemical laser, and its structure includes a seed laser, a primary injection amplifier and a secondary injection amplifier; the light output in the seed laser passes through a plane total reflection mirror Ⅰ7 and planar total reflection mirror Ⅱ8 are reflected into the primary injection amplifier, and the light amplified by the primary injection amplifier is output to the beam reducer through the planar total reflection mirror Ⅳ19, and the reduced beam enters the secondary injection amplifier and the amplified light output;
[0027] The primary injection amplifier includes a plano-concave mirror II9, and the center of the plano-concave mirror II9 is pr...
