利用反射型单壁碳纳米管作为可饱和吸收体，首次实现了Nd：YVO4/KTP绿光激光器的被动连续锁模。532 nm锁模脉冲宽度估计约为7.1微秒。在泵浦功率为7.35W时，获得了532 nm的最大平均输出功率为456 mW，对应的重复频率为87.14 MHz。单脉冲能量为5.23nJ，峰值功率为0.74nJ。
By using reflective single-walled carbon nanotube as the saturable absorber, passively continuous-wave mode-locked of Nd:YVO4/KTP green laser was realized for the first time. The 532 nm mode-locked pulse width was estimated to be approximately 7.1 ps. The maximum average output power of 456 mW at 532 nm was obtained at a pump power of 7.35 W, corresponding to the repetition rate of 87.14 MHz. The single pulse energy and peak power were 5.23 nJ and 0.74 kW, respectively.
