Abstract :
The polarisation self-modulated laser exhibits various ´polarisation modes´ which can be switched among themselves by varying the applied voltage of the intra-cavity electro-optic waveplate. Strong hysteresis tendencies are displayed in this switching behaviour and multistability has been observed. Switching among the modes can also be simply initiated by perturbing the diode laser with short current pulses.
