Abstract

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.
