Abstract

The invention relates to a dual-stage injection amplification device based on a high-power gas flow chemical laser system. The device includes a seed laser, a primary injection amplifier and a secondary injection amplifier. The seed laser is injected into the primary laser amplifier for amplification and then injected into the secondary amplifier. Structure for amplified output. Among them, the seed laser is a single-mode line-selected chemical laser, the primary injection amplifier adopts an "8" ring cavity structure, and the secondary injection amplifier adopts a rectangular cavity structure to realize the amplified output of the line-selected gas flow chemical laser. The invention can realize high-power, single-mode, and linearly polarized output of line-selected chemical lasers, and can be widely used in the fields of laser physics, laser chemistry, and the like.
