Using 2D distributed feedback for production of spatial coherent radiation from active medium

The simple model of a laser exploiting two-dimensional (2D) distributed feedback is developed. It is shown that 2D Bragg resonator formed by the structure with following modulation of dielectric constant: /spl epsiv/=/spl epsiv//sub 0/ cos(h~z)cos(h~x) can provide production of spatial coherent radi...

Summary:The simple model of a laser exploiting two-dimensional (2D) distributed feedback is developed. It is shown that 2D Bragg resonator formed by the structure with following modulation of dielectric constant: /spl epsiv/=/spl epsiv//sub 0/ cos(h~z)cos(h~x) can provide production of spatial coherent radiation from active medium of planar geometry.
