摘　　要：2μm激光在生产和科研中发挥着重要作用,常被用作中长波光参量振荡器的泵浦源。单掺Ho^(3+)离子固体激光器是产生高功率2μm激光的主要途径,是2μm激光领域的重要研究方向。本文设计了一种由掺Tm^(3+)离子光纤激光器泵浦的调Q Ho∶YAG固体激光器。该激光器可实现2090 nm单波长输出,平均功率最高可达36.1 W,斜效率达到61.4%。该激光器在15 kHz重复频率下,得到了脉宽72 ns,峰值功率33.6 kW的脉冲输出。该激光器采用光纤激光器泵浦和单Ho∶YAG晶体棒设计,结构紧凑,易于集成。2μm laser,which is always used as the pump source of mid-infrared OPO,plays a significant role in manufacture and scientific research.Bulk oscillator using Ho^(3+)doped crystal is the main method to produce high-power 2μm laser beam.A high power Q-switched Ho∶YAG oscillator pumped by a Tm^(3+)-doped fiber laser is presented.The maximum continuous output power of 36.1 W with a slope efficiency of 61.4%is achieved at the wavelength of 2090 nm.In the Q-switched regime,33.6 kW peak power and 72 ns pulse width are obtained at the pulse repetition frequency of 15 kHz.This oscillator contains a single Ho∶YAG crystal which makes it compact and suitable for integration.
