“…There is the practical meaning for studying the misalignment analysis of a combination-cylinder discharge CO 2 laser. The resonator mirror could be misaligned in the CCDCL due to the following: the vibration of environment, room temperature, imprecise design, error of adjustment, and so on [26,27]. All the resonator mirrors in the CCDCL [21] are aligned; so far, however, the misalignments of resonator mirrors of the CCDCL have not yet been reported.…”

The axes of a laser resonator will deviate away from the initial places when the combination-cylinder discharge CO₂ laser (CCDCL) is misaligned. The new cavity axes are established through using the misaligned augmented matrixes. The influences of the misalignments on the properties of the laser beams are studied in detail, such as the line deviations and angle deviations of oscillation beams in CCDCL, the near- and far-field distribution of output beams, the diffraction loss and output power, and the beam quality factor. It is shown that the influences of the misalignments on the above properties of the laser beams are obvious when the misaligned angle of the laser resonator exceeds 30 s. The studied results can afford references for the design of a CCDCL.
