154 kHz, ultra-low repetition rate, high-energy pulse, polarization maintaining, Er-doped fiber laser using single wall carbon nanotube polyimide film

Long ring-cavity, all-polarization maintaining, Er-doped fiber laser using single wall carbon nanotube polyimide film was demonstrated. Output pulses with pulse energy of 0.7~2.6 nJ were obtained at ultra low repetition rate of 943~154 kHz.
