title: Longitudinal mode control of a narrow-linewidth fiber laser by use of the intrinsic birefringence of the fiber laser.
abstract: We present preliminary experimental data that show that the intrinsic birefringence in a ring erbium fiber laser containing a length of standard communications-grade optical fiber can be used to inhibit longitudinal mode hops. Mode-hop-free operation for periods in excess of several hours is observed with resolution-limited linewidths of 240 kHz.
