摘要: 以垂直生长法自制的双壁碳纳米管(Double wall carbon nanotube, DWCNT)作为可饱和吸收体，在全固态Tm:Lu3Al5O12 (Tm:LuAG)激光器中实现了高功率双波长的调Q锁模运转，输出波长分别为2016 nm和2032 nm。以激光二极管(Laser diode, LD)为抽运源，选用5%的输出镜，当泵浦功率大于6.52 W，激光运转进入稳定调Q锁模状态。增加泵浦功率到20 W时，对应调Q锁模运转下的输出功率为1092 mW，斜效率为6.11%，重复频率为106.4 MHz，调制深度接近100%。
Abstract: Employing double-walled carbon nanotube (DWCNT) by vertical growth method as a saturable absorber, we demonstrate a high-power and dual-wavelength passively Q-switched mode-locked (QML) operation of an all-solid-state Tm:Lu3Al5O12 (Tm:LuAG) laser, and the wavelength is 2016 nm and 2032 nm. In this experiment, the laser is pumped by laser diode (LD), and when the pump power is greater than 6.52 W, the laser enters into a stable Q-switched mode-locked operation state by using 5% output coupler. When the pump power reaches 20 W, the Q-switched mode-locking output power is 1092 mW, the slope efficiency is 6.11%, the repetition frequency is 106.4 MHz, the corresponding single pulse energy is 10.26 nJ. Furthermore, the modulation depth is close to 100%.
