Abstract

The extended cavity diode lasers were stabilized using the first and third derivatives obtained by the frequency modulation method from the hyperfine resonances of the ⁸⁷Rb D₂ transition line. The frequency stability values were measured as 3.1 × 10^-12, 5.6 × 10^-13, and 1.9 × 10^-12 for integration times of 1, 10², and 10⁴ s, respectively, using the first derivatives of F=1 → F′=1 and F=1 → F′=2 resonances. By use of the third derivatives of F=2 → F′=1,3 and F=2 → F′=2,3 cross-over resonances, 4.0 × 10^-12 − 1 s, 5.7 × 10^-13 − 10² s, 9.3 × 10^-13 − 10⁴ s frequency stability values were obtained. These values compared with the results of the previous study obtained by the Zeeman modulation method.

通过频率和泽曼调制方法获得的二极管激光器频率稳定性

利用频率调制方法从 87Rb D2 过渡线的超频共振中获得的一阶导数和三阶导数稳定了扩展腔二极管激光器。使用 F=1 → F′=1 和 F=1 → F′=2 共振的一阶导数，在积分时间为 1、102 和 104 秒时，测得的频率稳定值分别为 3.1 × 10-12、5.6 × 10-13 和 1.9 × 10-12。利用 F=2 → F′=1,3 和 F=2 → F′=2,3 交叉共振的三次导数，得到了 4.0 × 10-12 - 1 秒、5.7 × 10-13 - 102 秒、9.3 × 10-13 - 104 秒的频率稳定值。这些值与之前通过泽曼调制方法获得的研究结果进行了比较。
