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.

Ultra Narrow Linewidth Single Frequency Fiber Laser - SMART SCI&TECH
A narrow linewidth laser refers to a laser with a narrower spectral linewidth. Our laser has a spectral linewidth as small as 1KHz and is widely used in fields such as optical communication, fiber optic sensing, spectral analysis, and scientific experiments.
