Considering the natural frequency weakening of a high power laser's optical precision mount matching with large aperture, the paper states an optical precision mount with large aperture, with its mechanical model built and its dynamic abilities analyzed. By contrasting theoretical analysis and test data of the optical precision mount with a φ420 mm mirror, the reasons for natural frequency weakening have been seeked. The optimized structure of the optical precision mount with large aperture has a first-mode elastomer pitching swing frequency of 157.788 Hz, which could meet the working condition under the intense vibration.
