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.

Key words: multiwalled carbon nanotube, LDendpumped, passively Qswitched modelocked
