A narrow-band laser is a key component in the structure of the distributed sensors and security systems based on them, as well as in the coherent fiber-optic measurement systems (FOMS). Due to the highly coherent pulses of a narrow-band laser that provide a high-contrast interference pattern in the reflected signal, unique sensitivity of the optical fiber to the external influences is achieved. A narrow-band semiconductor laser has been successfully commercialized in Russia. This highly stable compact laser has many potential applications in the field of sensors, LIDAR systems, acoustic and seismic sensors, and radio-photonic devices.
