Moku:Go Laser Lock Box
Compare all Laser Lock Boxes
Overview
The Moku:Go 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 the user-defined locking process to quickly lock to any zero-crossing on the demodulated error signal. With the Laser Lock Box application, Moku:Go is the most cost-effective laser-locking tool on the market.

Multiple embedded instruments
In addition to the Laser Lock Box, this instrument also includes an embedded oscilloscope, onboard high-speed waveform generator with a maximum frequency of up to 20 MHz, and more. The math channel features an FFT option for basic spectral analysis. You can also access the pop-out window for the programmable power supplies on M1 and M2 models.
Block diagram view
Get a bird’s-eye view of your control system and observe signals anywhere in the signal processing chain using the integrated oscilloscope. Use custom locking stages, synchronized scanning, and configurable output limiters optimized specifically for cavity stabilization systems.
Available on Moku:Go hardware
A powerful FPGA paired with a high-quality analog front-end make Moku:Go the most robust hardware in education, capable of complex, real-time digital signal processing. An integrated Wi-Fi hotspot and programmable power supplies ensure that students have the complete solution they need all four years (and beyond).
