Single-frequency lasers produce optical radiation concentrated around a single longitudinal frequency, providing the spectral purity and frequency stability required by demanding optical applications. Narrow linewidth and stable emission are particularly important where the laser interacts with well-defined atomic, molecular, or interferometric transitions.
Modulight’s single-frequency portfolio includes DBR and DFB semiconductor lasers as well as integrated laser systems. Products are available across a broad wavelength range, with configurations including packaged laser diodes, fiber-pigtailed modules, chip-on-carrier products, and MOPA systems.
Applications include spectroscopy, quantum technologies, metrology, sensing, optical communications, and scientific instrumentation where precise wavelength and low-noise optical output are essential.
