Interferometry is the science of extracting information from the interference patterns of light waves. At its core, the precision of any interferometric measurement—whether for gravitational wave detection, surface profiling, or fiber optic sensing—is fundamentally limited by the spectral purity of the light source. This spectral purity is defined by the laser linewidth, and its impact on measurement quality cannot be overstated.

An Acousto Optic Frequency Shifter (AOFS) is a device that uses sound waves in a crystal to diffract and shift the frequency of a laser beam. It relies on the interaction between light and acoustic waves generated by an RF driver. Because of its precision and speed, it is widely used in laser systems, spectroscopy, and optical communication.

A Fiber Acousto-Optic Modulator (Fiber AOM) is an optical device used to control and manipulate laser beams inside fiber-optic systems. It operates based on the acousto-optic effect, where sound waves traveling through a crystal create periodic variations in the refractive index. When a laser beam passes through this modulated region, the interaction causes the beam to diffract and shift in frequency.
