Abstract
Under the condition of ideal phase locking, output beams with excellent coherence from improved axisymmetric-fold-combination (ASFC) CO2 laser can be obtained. Unfortunately, misalignments are inevitable. The influence of the misalignment of holophote of fold cavity on phase locking is analyzed, and the light intensity distributions are given by numerical simulation. The conclusion is demonstrated that the method of phase locking of the CO2 laser is fully feasible under the conditions of the ideal and the misaligned. The results have shown that the effect of phase locking is still excellent when the misalignment angle is in the range of tolerance.
