We present a new analytical method to solve the basic Heisenberg-Langevin equations of the standard quantum model of a single-mode laser. The method is valid for describing microlasers operating in the strong coupling regime (cavity QED lasers). These lasers can exhibit fascinating properties: for example, the very notion of threshold may break down. Owing to the analytic solutions of the new model, the laser operation in the close-to-threshold regime can be studied, which leads us to a natural characterization of the threshold's behavior.
