We report on mode locking of a bulk Cr:YAG laser by using a transmission-type single-walled carbon nanotube saturable absorber. Stable and self-starting laser operation in the picosecond and femtosecond regimes is obtained at wavelengths around 1.5 microm. Tunable transform-limited sub-100 fs pulses are generated at a repetition rate of 85 MHz with an output power up to 110 mW.
我们通过使用透射型单壁碳纳米管可饱和吸收体实现了块状 Cr:YAG 激光器的锁模。在 1.5 微米附近波长处获得了皮秒和飞秒两种稳定的自启动激光运转模式。在 85MHz 的重复率下产生了可调谐的限幅亚 100fs 脉冲，输出功率高达 110mW。
