摘要

单晶光纤是具有准一维结构的功能晶体材料，结合了体块单晶优异的物化性能和传统光纤材料比表面积大的结构优势，是一种极具潜力的激光增益介质。目前单晶光纤激光的研究主要集中于连续激光输出，关于脉冲激光性能的研究相对较少。我们采用微下拉法(μ-PD)制备的Yb∶LuAG单晶光纤(SCF)作为增益介质，获得了输出功率大于4 W、斜效率21.66%、光束质量因子

接近于1的连续激光输出。在此基础上，采用MoTe

作为可饱和吸收体，实现了Yb∶LuAG SCF最高单脉冲能量3.39 μJ的被动调

脉冲激光输出。该工作为Yb∶LuAG SCF在全固态高功率连续和脉冲激光器中的应用提供了参考。

Abstract

Single crystal fiber is a kind of functional crystal material with quasi-one-dimensional structure

combining the excellent physical and chemical properties of bulk crystal with the structural advantages of large specific surface area of traditional optical fiber materials

which makes it a potential laser gain medium. At present

the research on single crystal fiber laser mainly focuses on continuous-wave laser output

while the research on its pulsed laser performance is relatively few. With Yb∶LuAG single crystal fiber (SCF) prepared by micro-pull-down method(μ-PD) as the gain medium

a continuous-wave laser output of more than 4 W with a slope efficiency of 21.66% was obtained. The beam quality factor

is close to 1. On this basis

the linear optical properties of saturable absorber(SA) MoTe

were tested

and the nonlinear saturable absorption characteristics at 532 nm and 1 064 nm were verified. Finally

a passive

-switched Yb∶LuAG single crystal fiber pulsed laser output with the highest single pulse energy of 3.39 μJ was realized. This work provides a reference for the application of Yb∶LuAG SCF in all-solid-state high-power continuous-wave and pulsed lasers.
