本文研究了分别用三次和五次谐波锁定的６３３ｎｍ碘稳定激光器的频差及频率复现性。实验表明，在一定条件下，五次谐波锁定的频率复现性可达±１×１０－１１量级。
In this paper, we study the frequency difference and frequency reproducibility of the 633nm Iodine Stabilized Laser with the third and fifth harmonic respectively. Experiments show that under certain conditions, the fifth harmonic lock frequency reproducibility up to ± 1 × 10-11 orders of magnitude.
