The influence of misalignment of an axisymmetrical folded-combined CO2 laser on output power

The influences of misalignments of an axisymmetrical folded-combined (ASFC) CO2 laser on the output power are studied in detail. The new cavity axes are established by using the misaligned matrixes corresponding to the misalignments of the output mirror and the discharge tube, and the diffraction losses of the cavity and the output powers are calculated. It is shown that the influences of the misalignments on the output power are significant when the misalignment angle of the output mirror exceeds 20 s. These calculated values afford references for the design of ASFC CO2 lasers.
