    Schematic configuration of a passive HML fiber laser with a CNTs-PVA film.
    (a) Absorption spectrum of the CNTs-PVA film. (b) Measured Raman spectrum of the CNTs-PVA film under a pump laser of 532 nm. (c) The measured nonlinear transmission of the CNTs-PVA film.
    Characteristics of pulses with 26.3 MHz fundamental repetition rate under 95.6 mW pump power: (a) RF spectrum with a 3.2 GHz span and 10 kHz resolution bandwidth. Inset is the corresponding optical spectrum. (b) Oscilloscope trace.
    Observed pulse train at 580 MHz repetition rate. Inset presents a pulse train within the range of 0.2 μs.
    RF spectrum over a 3.2 GHz span of the emitted light from the fiber laser. The RF peak of the insert map is 580 MHz.
    Optical spectrum of the pulses.
    (Color online) Autocorrelation trace of the pulses.
    Harmonic order as a function of pump power.
