Abstract
A single longitudinal mode narrow linewidth and low threshold all fiber laser arrangement is disclosed, constructed from a ring cavity, a gain portion in the ring cavity, an input-output coupling interposed within the cavity and pumping means connected to the ring cavity and to the grating such that, upon actuation of the pumping means, the arrangement acts as a laser.
Claims23
A distributed feedback ring laser arrangement comprising:
- a ring cavity;
- a gain portion in said ring cavity;
- an input coupling connected to said ring cavity;
- an output coupling connected to said ring cavity;
- a grating interposed within the gain portion of said ring cavity;
- and
- an optical pumping means connected to said grating within said gain portion of said ring cavity such that upon activation of said optical pumping means, said laser arrangement operates as a distributed feedback ring laser producing a laser output at said output coupling.
