High-Energy Passive Mode-Locking of Fiber Lasers

Figure 10

Periodic evolution observed in the full governing equations ((a) and (b), 𝑔₀=2.27), CQGLE ((c) and (d), 𝑔₀=2.2), and SGLE ((e) and (f), 𝑔₀=2.2). The simulated evolutions are shown in (a), (c), and (e) and the corresponding pseudocolor plots are shown in (b), (d), and (f). The rest of the parameters in the simulations are 𝐷=−0.4, 𝛼₁=0.1𝜋, 𝛼₂=0.554𝜋, 𝛼₃=0.23𝜋, 𝛼_𝑝=0.43𝜋, 𝐾=0.1, Γ=0.1, 𝑒₀=1, and 𝜏=0.2. The initial conditions in all the simulations are 𝜓(0,𝑡)=sech0.5𝑡 (from [29], 2011, IEEE).
