Achieving precise phase control in optical applications with digital phase-locked loops

22 February 2024 10:00 - 11:00

In sensitive optical applications, obtaining the most precise measurements often involves stabilizing the laser with an external reference. One way to synchronize the phase of a signal is by using a phase-locked loop (PLL).

During this presentation, Liquid Instruments will introduce the concept of phase locking and show you how to construct an optical PLL with FPGA-based instrumentation, using a fully digital lock-in amplifier, waveform generator, and phasemeter. You’ll see how to increase measurement precision, reduce experimental complexity, and minimize costs with flexible, software-defined instruments. You’ll also find out how to leverage Python for PLL control and feedback. Attend the webinar to learn:

• The fundamental components of a phase-locked loop.
• How a single FPGA-based system can help fast-track optical phase locking.
• How to use Python to implement digital PLLs.

The webinar will include a presentation, demonstration, and live Q&A session.
