Problems solved by technology

However, since rare earth ions tend to spontaneously form clusters during the high-temperature melting preparation process of quartz glass and cause concentration quenching, it is difficult for rare earth ions to have high doping in quartz glass.
Although in the practical application of rare earth doped silica fiber, the low absorption problem of low concentration of rare earth ions can be c

Abstract

The process of making Nd-Yb co-blended high silica laser glass includes the following steps: preparing porous glass; compounding mixed Nd-Yb ion solution; soaking the porous glass inside the mixed Nd-Yb ion solution for over 30 min; drying the porous glass in air at 200-800 deg.C; and sintering at 1100-1200 deg.C in a high temperature furnace to eliminate pores and to form dense transparent Nd-Yb co-blended high silica laser glass. Thus made Nd-Yb co-blended high silica laser glass has excellent physical performance, and can emit 950-1100 nm wide band light under the pump of 808 nm laser and realize xenon lamp pumped laser output.

technical field [0001] The invention relates to laser glass, in particular to a manufacturing method of neodymium-ytterbium co-doped high-silicon-oxygen laser glass. Background technique [0002] The rapid development of laser diode-pumped solid-state lasers provides an opportunity for the development of new laser dielectric materials. Rare earth neodymium and ytterbium ion co-doped glass has potential applications and is expected to become a new laser dielectric material. Nd-Yb co-doped glass pumped by 808nm semiconductor laser, Nd 3+ generated in ions 4 I 9 / 2 → 4 f 5 / 2 , 2 h 9 / 2 absorption, followed by a nonradiative transition to Nd 3+ Ionic 4 f 3 / 2 Energy level, Nd 3+ of 4 f 3 / 2 The energy level is slightly higher than that of Yb 3+ of 2 f 5 / 2 Energy level energy, and can make it energy transfer, so NdYb co-doped glass can produce broadband luminescence from 950 to 1100nm, and infrared laser can be generated in the laser resonator.
