Hollow fluorescent ceramic optical fiber for laser illumination and preparation method thereof
The invention discloses a hollow fluorescent ceramic optical fiber for laser illumination and a preparation method thereof, the hollow ceramic optical fiber is Ce < 3 + >: YAG or Ce < 3 + >: LuAG fluorescent ceramic co-doped with rare earth metal ions or transition metal ions, the hollow ceramic optical fiber is in a hollow cylinder shape, the outer diameter is 200-500 microns, and the inner diameter is 50-100 microns; the hollow fluorescent ceramic optical fiber is prepared by adopting an extrusion molding method, the hollow fluorescent ceramic optical fiber is excited from the end face by taking a blue light LD laser as an excitation light source, high-brightness green light or yellow light is emitted, and white light is emitted under the condition of co-doping red light ions. The hollow structure of the fluorescent ceramic optical fiber greatly increases the heat dissipation area, effectively solves the problem that the efficiency is reduced due to the thermal quenching effect of a light conversion material, is high in luminous efficiency, and has a certain long-distance transmission function; and the extrusion molding method can be used for large-batch preparation, the length of the ceramic prepared at one time can reach 10m, and the preparation method is suitable for industrial production.
本发明公开了一种激光照明用空心荧光陶瓷光纤及其制备方法，所述空心陶瓷光纤为共掺入稀土金属离子或过渡金属离子的Ce3+：YAG或者Ce3+：LuAG荧光陶瓷，其呈空心圆柱状，外径为200～500um，内径为50～100um；采用挤出成型方法制备出空心荧光陶瓷光纤，以蓝光LD激光器为激发光源从端面激发所述空心荧光陶瓷光纤，发射出高亮度的绿光或黄光，在共掺杂红光离子情况下发出白光。该荧光陶瓷光纤空心结构使散热面积大大提升，有效的解决了光转材料面临的热猝灭效应带来的效率下降的问题，发光效率高，具备一定的长距离传播功能；且采用挤出成型方法可大批量制备，一次性制备出的陶瓷长度可达10m，适合工业化生产。
