Laser rate equations are written and solved in the frequency domain for homogeneous as well as for inhomogeneous gain. The resulting laser model is capable of describing the fine structure as well as the dynamics of the laser frequency spectrum. The calculation shows that laser lines have a Lorentzian-like lineshape. The linewidth is found to be close to the spectral width of the cavity in case of inhomogeneous gain, whereas it is proved to approach the quantum limit for homogeneous gain.
