A simple model of a bad-cavity laser is presented based on Haken's master
equation for N pumped two-level atoms in a cavity. Via adiabatic
elimination of fast variables the whole photon statistics is solved
analytically near threshold. It is shown that the second order coherence
function 
has a very different behavior near threshold for a
bad-cavity laser compared to a good-cavity laser. The power spectrum
illustrates nicely the different time scales involved in the dynamics.
