Mapping of the pulse states of a fiber laser with ionic liquid gated carbon nanotube saturable absorber

This work investigates a space of pulse states reachable by electronic control of ionic liquid gated carbon nanotube absorber (ILGNA) implemented inside fiber mode-locked laser. Adjustment of a voltage applied on ILGNA and a current of a pumping diode provides a convenient way to switch between Q-switch, Mode-locking and Q-switch mode-locking regimes. Solitons with spectral width of 16 nm pulse duration of 500 fs with 22.32 MHz repetition rate at mode-locking regime, pulses with 1.6 μs with 48.6 kHz repetition rate were achieved.
