Weak versus strong harmonic-expansion analyses of self-pulsing lasers: I—the Laser Lorenz model

摘要: We apply a simple harmonic expansion method to the single-mode laser equations analyze their dynamic properties. First, we extend well-known small signal analysis predict transient pulsations of relaxation oscillations. Such transients are characteristic relaxing towards its long-term solution, at any level excitation, both beyond and below instability threshold. Secondly, strong properties solutions. These derived for typical examples, extending well boundary region domain, which field amplitude undergoes regular around zero-mean values.
