This code defines a laser diode with a wavelength of 440 nanometers, a gain of 100, and a threshold current of 10 milliamperes. It then sets up the differential equations that describe the dynamics of the laser diode and solves them numerically. The results of the simulation are plotted as a function of time.
This is just a simple example of how to simulate a blue laser diode using MATLAB.
