| Abstract: | A 1 550 nm single frequency narrow linewidth fiber laser is designed to meet the demand of sensor system. It adopts ring cavity configuration, uses 976 nm laser as the pump source, high concentration Er3＋-doped fiber as the gain medium, low concentration Er3＋-doped fiber as the saturable absorber to obtain reliable narrow linewidth laser output. When the pump power is 200 mW, the output power is 21 mW, linewidth is 7.2 kHz, wavelength stability is 1.26 pm, and the relative intensity noise is less than --102 dB/Hz1/2. |
