The Moku:Pro 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 “Tap-to-Lock” 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.
