Liquid Instruments Laser Lock Box
Precision Laser Frequency Stabilization
Overview
The Laser Lock Box from Liquid Instruments offers precision laser frequency stabilization with wideband performance up to 2 GHz and flexible scan waveforms. It supports up to eight simultaneous lock modules, featuring dual PID controllers with independently tuned fast and slow feedback paths. Users can visualize and fine-tune locking behavior in real-time using the integrated oscilloscope and leverage the "Lock Assist" function for locking to any zero-crossing in the error signal. This module is built on a high-speed and low-noise platform, making it a powerful tool for multi-laser stabilization, spectroscopy, and precision control experiments.
The Laser Lock Box enables locking a laser's frequency to a reference cavity or atomic transition using high-performance modulation locking techniques. It includes a "Lock Assist" feature for quickly locking to any zero-crossing on the demodulated error signal. With Multi-instrument Mode (MIM), multiple modules can be deployed simultaneously on a single Moku:Pro, sharing the same clock base.
