【 摘 要 】

Ray matrix formalism is used to represent a two-mirror resonator with a thermal lens in the middle. By tracking a ray vector, which starts from the place where the laser and H{sup -} beams intercept, through the optical cavity, the cavity property can be analyzed. The cavity design can be optimized in such a way that at the interception, the spacious jitter of the laser beam caused by the cavity misalignment is the minimum.
