用于原子物理学的简单、高功率二极管laser系统

A simple, powerful diode laser system for atomic physics

Andrew Daffurn, Rachel F. Offer, Aidan S. Arnold

摘要:

外腔半导体激光器由于其优异的经济性、相干长度和多功能性而在原子物理学和各种其他科学学科中无处不在。然而,对于更高功率的应用,种子激光器、注入锁定和放大器的组合可能迅速变得昂贵和复杂。在这里,我们提出了一个有用的,高功率,单二极管激光器的设计规格:$>210\,$ mW,$100\,$ ms线宽($427 \pm 7$)kHz,$>99\%$模式纯度,$10\,$ GHz模式跳自由调谐范围和$12\,$ nm粗调谐。简单的方法概述,以确定光谱纯度和线宽与最小的额外的基础设施。该激光器具有足够的功率在单室蒸汽加载的磁光阱中收集$10^{10}$ $^{87}$ Rb原子。通过适当的二极管和反馈,该系统可以很容易地适应其他原子种类和激光格式。

英文摘要:

External-cavity diode lasers are ubiquitous in atomic physics and a wide variety of other scientific disciplines, due to their excellent affordability, coherence length and versatility. However, for higher power applications, the combination of seed lasers, injection-locking and amplifiers can rapidly become expensive and complex. Here we present a useful, high-power, single-diode laser design with specifications: $>210\,$mW, $100\,$ms-linewidth ($427 \pm 7$) kHz, $>99\%$ mode purity, $10\,$GHz mode-hop-free tuning range and $12\,$nm coarse tuning. Simple methods are outlined to determine the spectral purity and linewidth with minimal additional infrastructure. The laser has sufficient power to collect $10^{10}$ $^{87}$Rb atoms in a single-chamber vapour-loaded magneto-optical trap. With appropriate diodes and feedback, the system could be easily adapted to other atomic species and laser formats.
