论文摘要
我们报告了用于激光频率稳定以及强度稳定和控制的数字控制器的开发，实施和表征。我们的设计基于STEMLAB（最初是红色Pitaya）平台。提出的模拟硬件接口为指定应用提供了所有必要的功能，并且可以集成在标准的19英寸机架安装单元中。打印的电路板布局可作为开源项目提供。\ cite {apqgit_lockbox，apqgit_intstab}详细的表征表明，带宽1.25 MHz，控制器的噪声性能受到stestlab系统的限制，并且不受补充硬件的影响。证明了二极管激光系统的频率稳定化，导致线宽为52（1）kHz（FWHM）。强度控制$ 10^{ - 3} $级别具有基于声音调制器作为执行器的次级微秒上升和降落时间。
We report on the development, implementation, and characterization of digital controllers for laser frequency stabilization as well as intensity stabilization and control. Our design is based on the STEMlab (originally Red Pitaya) platform. The presented analog hardware interfaces provide all necessary functionalities for the designated applications and can be integrated in standard 19-inch rack mount units. Printed circuit board layouts are made available as an open-source project.\cite{APQGit_Lockbox,APQGit_IntStab} A detailed characterization shows that the bandwidth 1.25 MHz and the noise performance of the controllers are limited by the STEMlab system and not affected by the supplementary hardware. Frequency stabilization of a diode laser system resulting in a linewidth of 52(1) kHz (FWHM) is demonstrated. Intensity control to the $10^{-3}$ level with sub-microsecond rise and fall times based on an acousto-optic modulator as actuator is achieved.
