    High-Performance PDH Locking with Reconfigurable Instrumentation

    The Pound-Drever-Hall method essential for laser frequency stabilization, but manual assembly can lead to significant maintenance challenges. Learn how to automate and accelerate laser locking with reconfigurable, FPGA-based instrumentation.

    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, Liquid Instruments provides a pedagogical introduction to the PDH technique and creates a system using reconfigurable, FPGA-based instrumentation. A real optical system is emulated with Moku, using a variety of onboard instruments including the Laser Lock Box.
