论文摘要
控制外部腔二极管激光（ECDL）的频率的能力是本科实验室和原子物理学研究的重要组成部分。通常，ECDL衍射光栅和压电传感器的外壳要么是商业购买的，要么是从金属购买的。在这里，我们提供了使用3D打印的这些常用选项的替代方法，该选项是许多物理部门可用的工具。我们使用原子光谱和自组织干涉法表征了ECDL系统的性能，并表明它足以用于本科光谱实验和许多研究应用，而这些研究应用是不需要极其狭窄的激光范围的。 3D打印设计的性能和负担能力使它们成为将来使用的吸引人的选择。
The ability to control the frequency of an external-cavity diode laser (ECDL) is an essential component for undergraduate laboratories and atomic physics research. Typically the housing for the ECDL's diffraction grating and piezoelectric transducer is either purchased commercially or machined from metal. Here, we present an alternative to these commonly used options that utilizes 3D printing, a tool available in many physics departments. We characterize the performance of our ECDL system using atomic spectroscopy and self-heterodyne interferometry and show that it is sufficient for use in undergraduate spectroscopy experiments and a number of research applications where extremely narrow laser linewidths are not necessary. The performance and affordability of 3D-printed designs make them an appealing option for future use.
