The laser generates pulses with pulses centered at 1593\u00a0nm, with a 3\u00a0dB bandwidth of 2.5\u00a0nm, a repetition rate of 4.5\u00a0MHz, a signal\u2010to\u2010noise ratio exceeding 60\u00a0dB, and maintains stable operation over 24\u00a0h. Beyond mode\u2010locked and Q\u2010switched regimes, the same laser system can be operated in an excitable regime, where isolated optical spikes are generated in response to external perturbations, exhibiting threshold\u2010like and all\u2010or\u2010none spiking behavior.
