| 摘 要： | 本文首次研究了以多壁碳纳米管（MWCNT）为饱和吸收体，Nd:YAG被动调Q锁模激光器的输出特性。激光器连续光（CW）和调Q锁模（QML）运转平均输出斜效率分别为35.7%和14.9%。实验得到的调Q包络重复频率在45.2~128.8 kHz范围内变化。最短调Q包络脉冲宽度为95 ns，仅包含10个锁模脉冲。最高调Q包络单脉冲能量和锁模脉冲单脉冲能量分别为14.6和1.31 μJ。锁模脉冲宽度约为461 ps，相应的最高峰值功率为2.84 kW。

| Abstract: | We originally addressed the output characteristics of a diode pumped passively Q switched mode locked Nd:YAG laser with a multi walled carbon nanotube (MWCNT) as a saturate absorbent. The average slop efficiencies of continuous wave (CW) and Q switched mode locking (QML) operation were 35.7% and 14.9%. Repetition rate of Q switched envelope varied from 45.2 to 128.8 kHz. Width of the shortest Q switched envelope pulse was 95 ns, containing only 10 mode locked pulses. The energies of maximal single Q switched envelope pulse and mode locked pulse were 14.6 and 1.31 μJ. The width of mode locked pulse was about 461 ps, whose highest peak power was 2.84 kW. |
