Abstract

The invention relates to a method for preparing a microsphere cavity laser based on ultra-strong up-conversion multi-component glass material, and belongs to the technical field of microsphere cavitylasers. The method comprises the preparation of Yb-Er ion co-doped multi-component fluorosilicate glass and Yb-Er ion co-doped glass microspheres. And the prepared microspheres are packaged by a laser. The Preparation method of microsphere cavity laser based on ultra-strong up-conversion multi-component glass material combines the ultra-high up-conversion quantum efficiency of Yb-Er ions in the fluorosilicate glass with the high quality factor of the glass microspheres, and solves the problems of uncontrollable crystallization in the development process of the prior-conversion optical fiber laser and the over-high pumping threshold value. According to the invention, the pumping light intensity is greatly enhanced through optical path coupling, resonance of the whispering wall mode is realized in Yb-Er co-doped fluorine silicate microspheres, and finally laser output with narrow line width is realized. The method is simple in preparation process, belongs to the wave band with the smallest transmission loss in seawater, can be used for naval equipment, and solves the problem of detection of underwater targets and marine communication.

Description

technical field [0001] The invention belongs to the technical field of microsphere cavity lasers, and in particular relates to a preparation method of microsphere cavity lasers based on super-intensive up-conversion multi-component glass materials. Background technique [0002] Optical microsphere cavity, which can trap light beams in very small microspheres, has high energy density and small mode field volume, and the optical mode that can be stably transmitted in the microsphere cavity is called whispering gallery mode. When the British scientist Lord Rayleigh studied the propagation of sound in the curved corridor of St. Paul's Cathedral, he found that he could clearly hear the whispering of two people far away from him at the other end of the corridor, so this mode of sound propagation was called "whispering". Corridor Mode". In fact, there is a similar phenomenon in the Whispering Wall in the Temple of Heaven in Beijing. Similar to the reflection of sound waves on the...
