Abstract:
A theory is given of dye solution lasers in which an allowance is made for the optical anisotropy of dye molecules. The calculated dependences of the degree of polarization of generated radiation on the azimuth of linearly polarized transverse pump radiation (polarization diagrams) and on the degree of excess above the threshold are shown to agree well with the experimental results. The anisotropy of absorption and stimulated emission is described using the antiheuristic part of the polarizability tensor (spatial coherent oscillator model). Specific calculations are made for models of parallel and orthogonal linear absorption and emission oscillators. A dye solution is regarded as a nonlinear amplifying quasicrystal.
