Abstract

The invention discloses an Er<3+> / Yb<3+> co-doped multi-component phosphate glass material with uniformly distributed silver nano-particles, and a preparation method thereof. The method comprises the following specific steps: raw materials P2O5, K2O, BaO, Al2O3, Nb2O5, Sb2O3, La2O3, Yb2O3, Er2O3, AgCl and SnO are uniformly mixed, and are molten in a crucible under a temperature of 1100-1250 DEG C; bulk glass obtained by melting is transferred in an annealing furnace, and is subjected to an annealing heat treatment under a temperature of 450-500 DEG C; and cutting and polishing are carried out, such that the Er<3+> / Yb<3+> co-doped multi-component phosphate glass material with uniformly distributed silver nano-particles is obtained. According to the invention, a small amount of stannous oxide is doped in multi-component phosphate glass, such that the silver nano-particles can be uniformly distributed in the glass body. Therefore, the 1.53mum luminous intensity of the multi-component glass can be enhanced.

Description

technical field [0001] The invention belongs to the field of rare earth luminescence, and in particular relates to an Er3 with uniform distribution of silver nanoparticles + / Yb3 + Co-doped multi-component phosphate glass material and method for its preparation. Background technique [0002] Fiber lasers have attracted much attention due to their small size, compactness, and ease of control. Due to their great coherence, single-frequency fiber lasers are in strong demand in the fields of high-resolution sensing, coherent communication, lidar, and long-distance detection. The short-cavity structure helps to obtain a narrow linewidth and low-noise all-fiber laser output, and is an effective way to realize single-frequency fiber laser. In 2003, Spiegelberg et al. reported that in Er 3+ / Yb 3+ DBR laser output at 1550 nm in co-doped phosphate glass fiber. A single-frequency laser was obtained in a 2cm-long optical fiber, the output power of the laser was more than 200mW, ...
