Soliton Fiber Ring Laser Stabilization and Tuning with a Broad Intracavity Filter

摘要

The periodic perturbations to the soliton in passively mode locked fiber solitonlasers cause dispersive wave shedding, which lead to sharp spectral sidebands that limit pulse duration. By using a broad intracavity birefringent plate filter, the sidebands are greatly reduced, and the pulse duration is shortened. The filter also allows wavelength tuning, and a 43 nm continuous tuning range is demonstrated for pulses of 311-357 fs duration in a fully self-starting diode pumped System.
