In this work the noise characteristics of the single-mode laser with a low-Q cavity are theoretically investigated. Eliminating adiabatically the electric field from the Maxwell-Bloch equations, coupled Langevin equations with both additive and multiplicative white noises are examined. They are solved by the Rice's method in a framework of the quasilinear Fourier analysis. Noise spectral densities are calculated analytically to discuss the dependence of the relative intensity noise (RIN) on the pumping. Investigating the auto- and cross-correlations of the light intensity and population noises, their variances are also obtained to predict their novel features in comparison with the good-cavity case. Assuming that a probability density of the light intensity is Rice's distribution, the stationary intensity cumulants, the photon counting coefficient, and the photon counting probability are explicitly derived and compared with the results by the Fokker-Planck analysis previously carried out in both the good- and bad-cavity cases.
