simulate a single pulse laser in matlab

main.m
% Define the laser parameters
lambda = 1064e-9;   % wavelength [m]
tau_pulse = 5e-9;   % pulse duration [s]
e_pulse = 1e-6;     % pulse energy [J]
dt = 1e-12;         % time step [s]

% Define the time axis
t = -5*tau_pulse : dt : 5*tau_pulse;

% Define the pulse envelope
envelope = (1 / (tau_pulse * sqrt(2*pi))) * exp(-(t/tau_pulse).^2/2);

% Normalize the pulse energy
envelope = sqrt(e_pulse) * envelope / norm(envelope);

% Create a laser beam object
laser = GaussianBeam(lambda, 'Waist', 0.1, 'RayleighDistance', 1);

% Propagate the laser pulse
pulse = laser.Propagate(t, envelope);

% Visualize the pulse
figure;
plot(t*1e9, abs(pulse).^2);
