Compact high-repetition-rate passive mode-locked resonant cavity structure and fiber laser

Abstract

Discloses are a compact high-repetition-rate passive mode-locked resonant cavity structure and a fiber laser, where a resonant cavity includes a first ferrule, a semiconductor saturable absorber mirror, a first sleeve, a gradient index lens, a second sleeve, a gain fiber, a second ferrule, and a dielectric film. The semiconductor saturable absorber mirror is disposed on one end surface of the first ferrule, the first ferrule is spacedly connected to one end of the gradient index lens via the first sleeve, the other end of the gradient index lens is spacedly connected to the second ferrule via the second sleeve, the dielectric film is disposed on the other end surface of the second ferrule, and the gain fiber is located in the second ferrule.
