Abstract: We show through numerical simulations that different kinds of noise have different signatures in the statistical distribution of the intensity peak height as a function of delay time in the turn-on of class-B lasers. Simulations are carried out specifically for a CO2 laser and are compared to the experimental results of H. Grassi et al. [Phys. Rev. A 50, 805 (1994)]. Full qualitative agreement is found with the experiment. These results confirm that noise on the control parameter has a larger influence on the laser behavior than the intrinsic fluctuations. A physical interpretation of the role that the different physical noise sources play in the system is offered.
