DSR in the case of saturating gain. (a) Pulse energy ‖𝜓‖² as a function of 𝑒₀ at 𝐷=−1.6 (top), 𝐷=−1.2 (middle), and 𝐷=−0.8 (bottom), respectively. The rest of the parameters are 𝑔₀=2.3991, 𝜏=0.1667, 𝛼₁=0.7863𝜋, 𝛼₂=0.3𝜋, 𝛼₃=𝛼_𝑝=0, 𝐾=0.1, and Γ=0.1. (b) The corresponding pulse shape (top) and frequency chirp profile (bottom) at 𝑒₀=5 (blue solid curves), 𝑒₀=58 (red dashed curves), and 𝑒₀=180 (green dash-dot curves) along the 𝐷=−1.6 line, respectively (from [44]).
