我们展示了基于调制的频率锁定的外腔二极管激光器，利用压电致动镜，外部的激光腔，从饱和吸收光谱创建一个错误信号。通过这种方法，稳定到铷超精细跃迁的激光在几秒钟内具有130 kHz的FWHM，使锁定的激光适用于原子物理学实验，例如创建和操纵玻色-爱因斯坦凝聚。这种技术结合了低幅度调制、简单性、性能和价格的优点，这些因素通常被认为是相互排斥的。(C)2008年美国光学学会
We demonstrate modulation-based frequency locking of an external cavity diode laser, utilizing a piezo-electrically actuated mirror, external to the laser cavity, to create an error signal from saturated absorption spectroscopy. With this method, a laser stabilized to a rubidium hyperfine transition has a FWHM of 130 kHz over seconds, making the locked laser suitable for experiments in atomic physics, such as creating and manipulating Bose-Einstein condensates. This technique combines the advantages of low-amplitude modulation, simplicity, performance, and price, factors that are usually considered to be mutually exclusive.
