| 简介 |
Provided is an all-fiber laser device oscillating in a mid-infrared wavelength band. The laser device uses a non-silica optical fiber for a gain medium. The non-silica optical fiber includes a core doped with a rare element having an energy transition level corresponding to the mid-infrared wavelength band. A Fabry-Parrot resonator or a ring-shaped resonator may be installed in the non-silica optical fiber. Alternatively, a silica optical fiber may be coupled to both ends of the non-silica optical fiber, and a Fabry-Parrot resonator or a ring-shaped resonator may be installed in the silica optical fiber. |
