Performance and versatility to advance discovery

Moku:Pro integrates crucial instruments for laser stabilization and measurement, like the Laser Lock Box and Lock-in Amplifier, while also providing test essentials such as the Oscilloscope and Waveform Generator. Thanks to the software-defined, multi-instrument platform, it's easy to integrate custom algorithms into your test sequence.

Lock-in detection

Utilize the 4-channel, 600 MHz Lock-in Amplifier for multiple frequencies or harmonics. Achieve ultra-low noise performance with 10+18-bit blended ADCs.

Laser locking

Easily lock lasers to a cavity using the Laser Lock Box. With Lock Assist, you can instantly lock to any zero-crossing on the demodulated error signal.

Optical PLLs

The integrated PID controller enables easy laser frequency stabilization and phase locking. Adjust parameters and view results in real time to optimize closed-loop control.
