Liquid Instruments SW-Pro-LLB Laser Lock Box

Overview

The Liquid Instruments SW-Pro-LLB is a laser frequency stabilization module for the Moku:Pro series that provides a complete solution for locking a laser's frequency to a reference cavity or atomic transition. It supports multiple locking techniques including Pound-Drever-Hall, heterodyne offset phase-locking, RF locking, and dither locking, with integrated high- and low-bandwidth PID controllers for independent fast and slow feedback control.

Key Features

• Demodulation frequency range: 1 mHz to 600 MHz
• Scan frequency: up to 10 MHz
• 2 input channels, 2 output channels
• Adjustable post-demodulation filter: 2.6 kHz to 35 MHz
• 16-bit DAC resolution
• 2 integrated PID controllers for fast and slow feedback
• Lock Assist feature for quick zero-crossing locking
• Internal PLL frequency multiplier (up to 250th harmonic)
• Filter types: Butterworth, Chebyshev, Chebyshev II, Elliptic, Cascaded, Gaussian, Bessel, Legendre
• Integrated 1.25 GSa/s oscilloscope for signal monitoring
• API support: Python, MATLAB, LabVIEW

Applications

• Custom phase-locked loop design
• Gravitational wave detection
• Closed-loop control systems
