Guided Mode Resonance Filter as a Spectrally Selective Feedback Element in a Double-Cladding Optical Fiber Laser

In this work, a spectrally selective optical element is introduced based on a 2-D guided mode resonance filter (GMRF) as an external feedback element. The GMRF was designed to provide a highly efficient narrow linewidth reflection within the gain bandwidth of the fiber laser, while transmitting the...

Zusammenfassung:In this work, a spectrally selective optical element is introduced based on a 2-D guided mode resonance filter (GMRF) as an external feedback element. The GMRF was designed to provide a highly efficient narrow linewidth reflection within the gain bandwidth of the fiber laser, while transmitting the pump beam. These features enabled the fiber laser to operate in an external cavity configuration to provide a wavelength-stabilized and narrow linewidth output within the optical -band.
