Abstract :
The behaviour of the relative intensity noise in each longitudinal mode of a CW DH AlGaAs laser exhibiting mode jumps is observed and theoretically explained. The stabilisation of the amplitude fluctuations of the main mode due to the gain saturation which could be expected when the injection current increases is cancelled by the shift of the maximum of the gain spectrum.
