提出了Tm：YAG和Ho：雅普集成增益介质用于二极管泵浦的2.1 μm激光器。·在2130 nm处，Tm：YAG/Ho：雅普激光器的最大输出功率为5.06 W。·结果验证了异质掺杂Tm和Ho晶体的集成。首次将异质掺Tm和掺Ho增益介质集成到单一体增益介质中，实现了一种紧凑的二极管泵浦Ho激光器。采用Tm：YAG腔内泵浦Ho：雅普方案实现了Ho激光的高效运转，最大输出功率为6.6W，考虑到二极管泵浦光的吸收，实现了Tm：YAG/Ho：雅普集成激光器，在2129.7nm处的最大输出功率为5.1W，对应的斜率效率为25.4%，光转换效率为21.6%。
• Tm:YAG and Ho:YAP integrated gain medium is proposed for a diode-pumped 2.1 μm laser. • The maximum output power of the integrated Tm:YAG/Ho:YAP laser is 5.06 W at 2130 nm. • The results verify the integration of heterogenous Tm-doped and Ho-doped crystals. We demonstrate a compact diode-pumped Ho laser via integrating heterogenous Tm-doped and Ho-doped gain media into a single bulk gain medium for the first time. After achieving efficient Ho laser operation from the Tm:YAG intra-cavity pumped Ho:YAP scheme, with an maximum output power of 6.6 W, the integrated Tm:YAG/Ho:YAP laser was realized with a maximum output power of 5.1 W at 2129.7 nm, corresponding to a slope efficiency of 25.4% and optical conversion efficiency of 21.6% by considering the absorbed diode pump power.
