| 英文摘要 | Based on the actual working environment, the thermal model of novel Tm: LuYAG crystal is established, and the transient thermal effect of pulsed laser diode single-end pumped Tm: LuYAG laser under different spot radius, pump power, repetition frequency, pulse width and duty ratio are simulated, analyzed, and discussed theoretically. The output characteristics of pulsed-LD end-pumped Tm: LuYAG laser are achieved and analyzed at different repetition frequencies and duty ratios experimentally. At repetition frequency of 10 Hz, 100 Hz, 1000 Hz and duty ratio of 50 %, the maximum output energy is 724 mJ, 70 mJ, 6.36 mJ, with the slope efficiency is 39.4 %, 38.2 % and 35.5 %, respectively. Moreover, at repetition frequency of 10 Hz and duty ratio of 75 %, the maximum output energy of 900 mJ is achieved with slope efficiency of 34.6 %. The central wavelength of Tm: LuYAG laser is measured to be 2018.96 nm, and the beam quality is M-x(2) = 1.96, M-y(2) = 1.98. To our knowledge, it is the first time to analyze the transient thermal effect of Tm: LuYAG crystal pumped by pulsed laser diode in detail. As far as we know, this is the maximum output energy based on the novel Tm: LuYAG crystal. |
