N2 - We propose and demonstrate a method for measuring the time evolution of the off-diagonal elements ρ_{n,n+k}(t) of the reduced density matrix obtained from the quantum theory of the laser. The decay rates of the off-diagonal matrix element ρ_{n,n+k}(t) (k = 2,3) are measured for the first time and compared with that of ρ_{n,n+1}(t), which corresponds to the linewidth of the laser. The experimental results agree with the Scully-Lamb quantum theory of the laser.
