Introduction

Laser locking systems are used to control and match a laser’s frequency to an optical frequency

reference, such as an optical reference cavity or atomic transition. Such systems are vital for high-

resolution interferometric measurements, spectroscopy, and time and frequency standards.

Locking a laser by forcing the laser and reference frequencies to be equal allows for two scenarios:

• The locking system steers the laser frequency to be equal to the reference frequency,

which is referred to as frequency stabilization; and

• The locking system forces the reference frequency to follow the laser frequency, which is

referred to as frequency tracking.

Whether used for frequency stabilization or frequency tracking, the Moku:Go Laser Lock Box is

designed to assist in laser locking systems. It offers compact setup, acquisition, and diagnostic

features that makes it easier and quicker to set up and characterize laser locking systems.
