- Abstract
The output far-field intensity distributions of off-axial cylindrical hybrid resonator with different mirror mis- alignments are simulated by coordinate transformation fast Fourier-transform algorithm. The simulations showed that the mirror misalignments influence is different in anticlockwise and clockwise tilt direction. According to the calculation results, the output beam quality of off-axial unstable resonator is analyzed, from the aspects of M2 value and power in the bucket curves. Furthermore, the analysis brings out an interesting contradiction that the beam quality changing evaluated by M2 value is different from that by power in the bucket curves when the mirror misalignments occurred in anticlockwise direction. It demonstrated that the beam quality evaluation of off-axial unstable resonator should not be one-sided.
