We study theoretically the lasing properties and the cavity lifetime of super and sub-luminal lasers. We find that obtaining the necessary conditions for superluminal lasing is rather difficult and that laser operating under these conditions are unstable and tend to bi-frequency lasing. We study the relaxation time of power perturbation in super and sub-luminal lasers using a finite-difference-time-domain-tool and present the impact between the lasing power, the group velocity and the dispersion properties of the cavity on the relaxation dynamic of such perturbations.
