Abstract
The soliton pulse shaping mechanism dominates ultrashort pulse generation in both passively and actively mode-locked lasers.1–3 In this paper, we studied the soliton stability conditions in actively mode-locked lasers with different degree of inhomogeneity. Numerical simulation shows that for an inhomogeneously broadened laser, a stable single soliton-like pulse can be generated only within a certain negative group velocity dispersion (GVD) region. Experimental results confirmed the trend for the GVD requirement.
