Brief
The article proposes and experimentally demonstrates a fiber laser utilizing a hybrid cavity that combines a linear fiber cavity and a Whispering Gallery Mode (WGM) resonator for dual stabilization, enabling stable single- to four-mode operation with high signal-to-noise ratio and narrow line-width.
Summary
The paper demonstrates a fiber laser using a hybrid cavity which combines a linear fiber cavity and a Whispering Gallery Mode (WGM) resonator. This configuration provides dual stabilization for the laser mode, enabling stable single-mode operation with high signal-to-noise ratio (up to 61 dB) and narrow linewidth (down to ∼5 kHz), and also stable two- to four-mode operation without mode hopping.
