摘要

采用C离子注入和飞秒激光烧蚀相结合的方法，在Pr3+掺杂的Lu3Al5O12 （Pr:LuAG）晶体中制备了平面波导和脊波导。利用SRIM软件模拟了6.0 MeV C离子在Pr:LuAG晶体中的能量损失。为了评估波导的光约束能力，采用棱镜耦合系统测量了暗模光谱，并采用端面耦合方法获得了近场模式分布。通过光致发光发射光谱和衰减曲线研究了Pr3+离子的荧光特性。利用拉曼光谱和反射差光谱（RDS）对波导的微观结构进行了表征。

Optical waveguides in Pr:LuAG crystals fabricated by carbon ion implantation and femtosecond laser ablation

By combining C ion implantation with femtosecond laser ablation, the planar and ridge waveguides were fabricated in Pr³⁺-doped Lu₃Al₅O₁₂ (Pr:LuAG) crystals. The energy loss of 6.0 MeV C ions into Pr:LuAG crystal was simulated using the Stopping and Range of Ions in Matter (SRIM) software. To assess the optical confinement capabilities of the waveguides, the dark mode spectra were measured by a prism-coupling system, and the end-face coupling method was employed to acquire the near-field mode distribution. Fluorescent characteristics of Pr³⁺ ions were investigated through photoluminescence emission spectra and decay curves. The waveguide microstructures were characterized by Raman spectroscopy and reflectance-difference spectroscopy (RDS).
