Simple Technique Tunes a Fiber Laser’s Wavelength

BRECK HITZ

The broad spectral linewidths of fiber lasers make them attractive candidates for versatile, wavelength-tunable sources, but the wavelength-tuning mechanisms — often involving multimode fiber Bragg gratings or other complex components — are neither inexpensive nor simple. Recently, scientists at Centro de Investigaciones en Óptica in León, Mexico, and at the University of Central Florida in Orlando developed a straightforward technique that they believe can lead to very cost-effective wavelength-tunable fiber lasers.
