M. Kaczmarek et al., THRESHOLD CONDITIONS AND INTENSITY RELATIONS IN DOUBLE-COLOR-PUMPED OSCILLATIONS, Journal of the Optical Society of America. B, Optical physics, 11(1), 1994, pp. 136-142
The double-color-pumped oscillation process is studied, both theoretic
ally and experimentally, in photorefractive crystals. One-dimensional
steady-state theory is described, providing a basis for numerical mode
ling. 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, photoexci
tation rates, and absorption, is discussed. A good fit between numeric
al results and the experimental data is shown.
