Abstract:
1. A ring cavity laser device, comprising: a first mirror with a first reflective surface; a second mirror with a second reflective surface at least partially facing the first reflective surface of the first mirror; a third mirror with a third reflective surface at least partially facing the first reflective surface of the first mirror and the second reflective surface of the second mirror, the first, second and third mirrors defining an optical ring cavity to establish a resonant optical cavity in which electromagnetic energy is amplified by stimulated emission of coherent radiation that is partially transmitted through the second mirror; an optical gain medium disposed at least partially between the first and second mirrors; an electrical or optical pump providing energy to the optical gain medium; and a graphene saturable absorber disposed at least partially between the second and third reflective surfaces.
