Brillouin lasing in a single-mode tellurite fiber.
We demonstrate Brillouin lasing in a single-mode TeO(2)-Bi(2)O(3)-ZnO-Na(2)O tellurite fiber. A peak value of Brillouin gain coefficients of 1.6989 x 10(-10) m/W is measured on the basis of gain characteristics. An all-fiber Brillouin laser with a maximum unsaturated power of 54.6 mW at 1550 nm and a slope efficiency of 38.2% are achieved from a 200 m tellurite fiber by employing a ring cavity. In addition, a tunable Brillouin comb tellurite fiber laser is demonstrated.
