Abstract

The invention relates to the technical field of lasers, in particular to a debugging-free ring laser resonant cavity which comprises an optical base and m cavity mirrors used for forming an annular resonant cavity, the cavity mirrors are installed on resonant cavity mirror brackets respectively, the m resonant cavity mirror brackets and the optical base are integrally arranged, and the m resonant cavity mirror brackets and the optical base are integrally arranged. An optical wedge pair used for correcting an optical path to a closed optical cavity is arranged on the optical path of the resonant cavity formed by the m cavity mirrors, the wedge angle of the optical wedge pair is alpha, and m is larger than or equal to 3; n is the refractive index of the optical wedge; and theta is the installation angle deviation between the adjacent cavity mirrors. According to the debugging-free ring laser resonant cavity, the resonant cavity mirror bracket and the optical base are integrally arranged, and the optical wedge pair is arranged on the optical path of the resonant cavity to adjust the optical path to a closed optical cavity, so that compared with an existing ring laser resonant cavity, the shock resistance and vibration resistance of the resonant cavity are effectively improved; moreover, the debugging complexity of the resonant cavity is greatly reduced, and the debugging efficiency is improved.
