Figure 5From: Coherently driven degenerate three-level laser with parametric amplifierThe mean of the photon number. The mean of the photon number [Eq. (76) with β = 0.04, A = 100, and κ = 0.8] versus η for ε = μ = 0 (solid curve), for ε = 3.5 and μ = 0 (dashed curve), and for ε = 3.5 and μ = 5 (dotted curve).Back to article page
