High-performance PDH locking with reconfigurable instrumentation

Overview

The Pound-Drever-Hall (PDH) method is ubiquitous in fields requiring laser frequency stabilization, including atomic physics, spectroscopy, and precision measurement. However, since PDH systems are traditionally assembled manually from various components, they often present challenges for researchers due to time constraints and adaptability issues, leading to maintenance difficulties and signal distortion.

In this presentation, we provide a pedagogical introduction to the PDH technique and create a system using reconfigurable, FPGA-based instrumentation. We also combine multiple instruments, including the Moku Laser Lock Box, into a bespoke environment that emulates a real optical system. Together, the easy-to-use Moku software interface, suite of FPGA-based instruments, and powerful hardware provide flexible new ways to improve SNR, consolidate legacy test equipment, and significantly reduce time to innovation.

Join us to:

•  Learn how an integrated approach enables instant tuning of control loop parameters and demodulation phase, multiple preconfigured locking stages, and instant, single-click locking.
• See how Moku’s digital-first approach simplifies the laser locking process while automating maintenance against disturbances and delivering higher-quality data.

The webinar includes a presentation, demonstration, and live Q&A session. Presented in partnership with Photonics Media.
