Exploring laser frequency stabilization and laser locking techniques
The laser is one of the most important inventions of the 20th century, as far as experimental physics is concerned. Since the first demonstration of a laser in 1960, they have become ubiquitous in research labs across the world, forming a cornerstone of modern optics and quantum research. Laser stabilization, also known as laser locking,…

Laser locking with closed-loop transfer function measurement
Multi-instrument Mode on Moku:Pro allows you to lock lasers to optical cavities with the Laser Lock Box while also measuring the Bode plots by using the Frequency Response Analyzer (FRA) with no additional test equipment or wiring. By injecting a disturbance into the error signal and measuring the transfer function using the FRA, you can check…

Resonator length stabilization with the Moku:Pro Laser Lock Box at the University of Münster
Introduction At the University of Münster, a top educational institution in Germany that offers degree programs in more than 120 fields, Ph.D. student Michael Zwilich is working hard to characterize beams with different spatial profiles. Instead of suppressing the higher-order transverse modes, much like in typical gravitational wave detection methods with a single-frequency Gaussian beam,…
