Lanthanide-doped nanocrystals in high-Q microtoroids for stable on-chip white-light lasers
文献摘要：
The plentiful energy states of lanthanide(Ln3+)-doped nanomaterials make them very promising for on-chip integrated white-light lasers.Despite the rapid progresses,the Ln3+-based white upconversion emissions are strongly restricted by their low upconversion quantum efficiency and the color stability.Herein,we combine the CaF2∶Yb35Tm1.5Er0.5 nanocrystals and the high-Q microtoroids,and experimentally demonstrate the chip-integrated stable white-light laser.By optimizing the sizes,density,and distributions of Ln3+-doped nano-crystals,the Q factors of Ln3+-doped microtoroids are maintained as high as 5 × 105.The strong light matter interaction in high-Q microtoroids greatly enhances the upconversion emission and dramatically reduces the laser thresholds at 652 nm,545 nm,and 475 nm to similarly low values(1.89-2.10 mJ cm-2).Consequently,robust white-light microlaser has been experimentally achieved from a single microtoroid.This research has paved a solid step toward the chip-scale integrated broadband microlasers.
