Artificial neural network for the noise characteristics of laser modeling

Through the research of rate equation with Langevin noise of laser, the artificial neural network model for the characteristics of the noise of laser is developed. The value of theoretical calculation is used to provide training and testing samples for the artificial neural network model, then, the noise of laser can be analyzed using the trained neural network. The results of simulation and design are well agreed with those of numerical calculation. The method has the advantages of reliability, accuracy, time saving and high efficiency.
