Abstract

The double-color-pumped oscillation process is studied, both theoretically and experimentally, in photorefractive crystals. One-dimensional steady-state theory is described, providing a basis for numerical modeling. Threshold conditions are analyzed, the intensity performance of oscillation beams is investigated, and the influence of input incident power, as well as such parameters as coupling coefficients, photoexcitation rates, and absorption, is discussed. A good fit between numerical results and the experimental data is shown.
