摘要
用Nd :YVO4/KTP腔内倍频环形激光器产生的 5 32nm波长激光 ,探测到了波长在 5 32 .170nm至 5 32 .2 0 0nm范围的一系列碘的多普勒吸收谱线和饱和吸收谱线。理论计算出相应的波长值和超精细谱线结构参数。理论计算值与实验测量数据在较高的精度内相一致。用三次谐波锁定的稳频电路实现了该激光器在碘饱和吸收线超精细分量上的频率稳定。
Absorption spectra and its hyperfine components from wavelength 532.170nm to 532.200nm were detected using a Nd:YVO 4/KTP ring laser. Theoretical calculation is given and it is in good agreement with the experiment result. Laser frequency was stabilized on some of the hyperfine components with third harmonic technique.
