| 摘 要： | 根据速率方程，研究了二镜腔Nd:YAG双波长调Q激光的振荡机理.通过分析不同透过率下的竞争过程，研究了双波长激光振荡的特点.研究结果表明，在调Q过程中1319nm激光的调Q脉冲起振时间滞后于1064nm激光，并且其最终调Q脉冲来自调Q之后的第一个弛豫振荡尖峰，是该弛豫振荡抑制掉其他弛豫振荡后的结果.通过振荡机理分析，得到了双波长脉冲输出能量相当的透过率条件.

| Abstract: | The oscillation mechanism of dual-wavelength Nd:YAG Q-switched laser with two-mirror resonator is studied on the basis of the rate equation. The characteristics of the dual-wavelength laser are discussed by analysing the competition process with different transmissivities. Results show that the oscillating time of the Q-switched pulse laser for 1319nm laser is delayed relative to that of 1064nm. The 1319nm Q-switched laser is formed finally from the first relaxation oscillation spike after the Q-switch opening, i.e. it restrains the rest relaxation oscillation spikes. The transmissivity of relatively balanced output energy is theoretically obtained. |
