Single-frequency fiber lasers using rare-earth-doped silica

Single-frequency fiber lasers using rare-earth-doped silica

June 27, 2015: A single-frequency laser operates with only one longitudinal mode, and thus can emit quasi-monochromatic radiation with a very narrow linewidth and low noise. Such lasers, both in continuous waveform and pulsed operations, are of interest for interferometric sensing, coherent light detection and ranging, laser spectroscopy, and laser nonlinear frequency conversions. The distributed Bragg reflector (DBR) fiber laser ...
