摘要
We have observed laser oscillation in structures where the feedback mechanism is provided by Bragg scattering from planes of a crystalline array formed by an ordered suspension of polystyrene microspheres. We have also determined the threshold condition for oscillation in the low gain limit approximation using a coupled-wave model that includes results from the dynamical theory of X-ray diffraction. © 1990.
