Abstract

The dye ring laser, like other homogeneously broadened two-mode lasers, is predicted to have a steady state with two distinct regions of metastability.^1-3 If we write for the probability density of the two-mode intensities I₁, I₂ where U(I₁,I₂) is the steady state potential, then U(I₁,I₂) has the form in dimensionless units where a₁, a₂ are pump parameters of the two laser modes, and ξ=2 is the mode coupling constant.⁴ A two-dimensional plot of the surface U(I₁,I₂) exhibits minima at I₁=a₁, I₂=0, and I₁=0, I₂=a₂ with a saddle point in between.⁵
