摘要
Yttrium vanadate (YVO4) is recognized as one of the leading candidates in photonics that can support Raman laser operation and host various types of active dopants. However, it is normally used in the form of single crystal. Here, we report the successful fabrication of non-crystalline YVO4fiber using the melt-in-tube technique for the first time. Benefiting from the prevention of unexpected element diffusion, the fabricated fiber exhibits a perfect core-clad configuration and the core is composed of non-crystalline YVO4. In addition, controllable crystallization of non-crystalline YVO4fiber can be realized under external field stimulation. Fully and space-selectively crystallized YVO4fiber can be fabricated based on the heat-treatment and laser irradiation, respectively. The strategy can be potentially applied to various non-crystalline materials, pointing to promising applications in active photonics.
