Laser Lock Box
The Moku Laser Lock Box enables you to lock a laser’s frequency to a reference cavity or atomic transition using high-performance modulation locking techniques. The Laser Lock Box includes a Lock Assist feature, enabling you to quickly lock to any zero crossing on the demodulated error signal.
With Multi-instrument Mode, you can deploy up to four laser lock modules simultaneously. Each module shares the same clock base from the internal or an external source. This is the ideal solution for multi-laser stabilization systems.

Key benefits
From a built-in Data Logger and Oscilloscope to the ability to perform laser locking with various techniques, you can expect more from the Moku Laser Lock Box.

Block diagram view for enhanced signal visualization
Get a bird’s-eye view of your control system and observe signals anywhere in the signal processing chain using the integrated Oscilloscope. Use conditional triggering, synchronized scanning, and configurable output limiters optimized specifically for cavity stabilization systems.

High-performance frequency stabilization without the clutter
Moku devices can replace standalone waveform generators, phase shifters, demodulators, filters, and PID controllers. With high-performance digital signal processing, powerful visualization, and a flexible user interface, Moku devices deliver an all-in-one solution for laser frequency stabilization.

Painless laser locking with your preferred technique
From PDH locking to dither locking, integrate the Laser Lock Box in with your setup for faster, easier laser stabilization. Easily lock lasers to a cavity with limited manual intervention with Lock Assist. Tap to instantly lock on to any zero crossing on the demodulated error signal.

Freedom in the lab when you need it
With Moku software for iPad, you’re not tethered to your bench. Use the helpful Lock Assist feature in the Moku Laser Lock Box to tap to lock your laser’s frequency while you move freely throughout the lab.
