Stable Four-Wavelength Switchable Narrow-Linewidth Thulium-Holmium Co-Doped Fiber Laser Based on Dual-Cascaded PM-FBGs

This paper proposes a stable four-wavelength switchable narrow-linewidth thulium-holmium co-doped fiber laser based on dual-cascaded polarization-maintaining fiber Bragg gratings (PM-FBGs). Operating in the 1.94 μm band with a linear cavity configuration, wavelength switching is achieved by a...
