Document Type and Number:
WIPO Patent Application WO/2019/134111
Kind Code:
Provided is a mid-infrared optical fiber laser, comprising a pump source (1), a lens assembly (2), and a resonant cavity; the lens assembly (2) is placed between the pump source (1) and the resonant cavity; the pump source (1) is used for generating pump light; the pump light is transmitted through the lens assembly (2), collimated and focused, and then transmitted to the resonant cavity; the resonant cavity converts the pump light into a pulsed laser and outputs the pulsed laser; the resonant cavity comprises an optical fiber (3), a reflector set (4), an output coupling mirror (5), and a saturable absorber (6) using multilayer molybdenum disulfide as a saturable absorbing body. The saturable absorption spectrum of the multilayer molybdenum disulfide is broad and may extend to the mid-infrared band, such that the mid-infrared optical fiber laser can achieve the output of a mid-infrared pulsed laser in the 3-micron band.
