SUMMARY
The second-order correlation function (g2) for non-ideal lasers is typically greater than 1 at zero delay, contrasting with the constant value of 1 for ideal lasers. This function decays towards 1 as the delay increases, with the decay rate influenced by the coherence time of the laser. For thermal light sources, g2 can reach a value of 2. The specific decay shape is contingent upon the underlying reasons for the laser's non-ideal behavior.
