报道了一种采用单壁碳纳米管可饱和吸收体(SWCNT-SA)的钛宝石激光器的被动锁模。在99.4 MHz的重复频率下产生了短至62fs的锁模脉冲。利用SWCNT-SA锁模激光器获得了高达600 mW的输出功率，斜率效率为26%。比较了单壁碳纳米管SA辅助锁模和不加单壁碳纳米管SA的克尔透镜锁模的特性。(C)2011年美国光学学会
We report on passive mode-locking of a Ti:sapphire laser employing a single-walled carbon nanotube saturable absorber (SWCNT-SA) specially designed and fabricated for wavelengths near 800 nm. Mode-locked pulses as short as 62 fs were generated at a repetition rate of 99.4 MHz. We achieved output powers from the SWCNT-SA mode-locked laser as high as 600 mW with a slope efficiency of 26%. The characteristics of SWCNT-SA-assisted mode-locking were compared with those of Kerr-lens mode-locking without SWCNT-SA. (C) 2011 Optical Society of America
