将SiO2含量超过97wt%的具有纳米级微孔的多孔高硅氧玻璃浸泡在含有Nd3+离子的溶液后取出,在1100℃烧 结成透明无孔高硅氧玻璃。在800nm的激光抽运下,这种Nd3+离子掺杂的高硅氧玻璃微片激光器实现了斜率效率为62%, 光-光转换效率为42％,波长为1064nm的激光输出。
Porous high silica glass with nano-sized pores with SiO2 content over 97wt% is immersed in a solution containing Nd3 + ions, taken out and sintered at 1100 ℃ into a transparent non-porous high silica glass. This Nd3 + ion-doped high-silica glass microchip laser achieves laser output with a slope efficiency of 62%, a light-to-light conversion efficiency of 42% and a wavelength of 1064 nm at 800 nm laser pumping.
