Product Details

Narrow-linewidth Fiber Laser

Narrow-linewidth fiber lasers are specially designed lasers with extremely narrow spectral linewidths. Spectral linewidth refers to the range of frequency differences in an optical signal, typically expressed as bandwidth per unit frequency. The spectral linewidth of narrow-linewidth fiber lasers is usually between several hundred kilohertz and several megahertz, much narrower than that of ordinary lasers. These specially designed lasers play a crucial role in many fields, including optical communication, fiber optic sensing, and spectral analysis.
