Abstract

We report a frequency-stabilized semiconductor disk laser based on AlGaInP and operating at 689 nm, a wavelength of interest for atomic clocks based on strontium atoms. With a gain structure designed for emission at around 690 nm, more than 100 mW of output power are generated in single-frequency operation. We show that the source can be tuned over 8 nm with pm precision. By servo-locking the frequency to the side of fringe of a reference cavity, we demonstrate rms frequency noise of 5.2 kHz.

摘要

我们报道了一种基于AlGaInP且工作在689nm的频率稳定半导体盘激光器，该波长对于基于锶原子的原子钟来说是一个感兴趣的波长。通过设计用于在690nm左右发射的增益结构，单频运行时可产生超过100mW的输出功率。我们表明该光源可在8nm范围内以皮米精度进行调谐。通过将频率伺服锁定到参考腔条纹的一侧，我们展示了5.2kHz的均方根频率噪声。
