Wavelength region – 1064nm/1555nm/1970nm
Fiber optics laser resonators FOLR is a part of the fiber laser which used to produce single-mode laser radiation in a continuous generation mode.
The fiber resonator includes an active double-clad fiber and mirrors based on Refractive Index Fiber Bragg gratings recorded on optical fibers, which welded to the active fiber from both sides to form a feedback.
To create a full-fledged laser, it is required to connect a pump source in the range of 907-970 nm.
