Embodiment Construction
[0023] As shown in the accompanying drawings, the chemical laser device for seed injection and amplification ring cavity of the present invention includes a seed laser 1, an injection amplification stage 2 and an isolator 3, and the light output in the seed laser 1 is reflected by a plane total reflection mirror 7 and enters the isolation A device 3, after being unidirectionally isolated by the isolator 3, enters the injection amplifier stage 2 for amplification and outputs the amplified light;
[0024] The seed laser includes a planar diffraction grating 11, a diaphragm 12, a Brewster plate I13, a seed light gain area 14, a Brewster plate II15, and a plano-concave output coupling mirror 16 arranged in sequence along the forward direction of the output laser light;
[0025] The isolator 3 is made up of a polarizer 31 and a 1 / 4 wave plate 32; the polarizer 31 is placed on one side adjacent to the plane total reflection mirror 7, and the angle with the optical axis a is 54.5°; th...
