Abstract

The cavity axes change when the output mirror is misaligned because these cavities possess a common output mirror. We use 4 × 4 augmented matrices to establish new cavity axes, which result in different line deviations for different cavities. These deviations increase the diffraction losses and decrease the output power. The coordinate transforms are used to solve the output light fields because the output beams do not have a common propagation direction. We show that the shapes of the combined laser beams change when the output mirror is misaligned. These studies provide references for the design and application of CO 2 lasers.
