激光加热基座法生长高质量Yb3+掺杂Y3Al5O12单晶光纤
Growth of High-quality Yb3+-doped Y3Al5O12 Single Crystal Fiber by Laser Heated Pedestal Growth Method
摘要
Abstract
Single-crystal fiber (SCF) is a fiber-shaped monocrystalline material, which is an important tendency for the development of low-dimensional functional crystals. Combining the excellent optical properties of bulk crystals and the high-efficient thermal dissipation as well as the high beam quality of optical fibers, SCFs are believed to solve the bottlenecks of conventional laser fibers such as unfavorable non-linear effects and poor thermal conductivities, can thus achieve higher laser peak powers and pulse energy. Here, we describe the results of synthesis and characterization of two Yb3+-doped Y3Al5O12 (Yb:YAG) SCFs (Ф0.2 mm×710 mm), which were grown by a self- developed laser-heated pedestal growth (LHPG) apparatus. The prepared SCFs possess a length-to-diameter ratio greater than 3500, a diameter fluctuation less than 5％, and show high flexibility for bending. The analysis of X-ray rocking curve indicates that the crystallinity of the grown SCF is improved compared with that of the source rod. The EDS line scan shows that the Yb3+ ions are uniformly distributed along the axial direction. Results of these characterizations of SCFs indicate that SCFs maintains excellent crystallinity and high optical homogeneity, showing promising candidate for high-power laser applications.关键词
