Laser Lock Box

Moku:Lab''s 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. It also features an integrated 2‑channel oscilloscope, allowing you to observe signals at any point in the signal processing chain at up to 500 MSa/s.

Features
