# Three-Dimensional Rendering Of the Electric Field

Three-dimensional rendering of the electric ﬁeld from numerical calculations in a random laser in which the yellow spheres represent the nanoparticles in a cylindrically symmetric gain medium. The electric ﬁeld, where color and height indicate intensity, represents the steady-state solution of the Maxwell-Bloch system of equations.
