Is random lasing possible with a cold atom cloud?

(PhysOrg.com) -- Random lasing, Robin Kaiser tells PhysOrg.com, is like standard lasing, with a little bit of a twist: `You don`t know the direction the photons will go, as you do with a more standard laser. This is because the feedback normally produced by a cavity, which sets a propagation axis, is now provided by multiple scattering in all directions. Light is randomly scattered throughout the structure of the laser, exciting further light-emitting processes. Light in a random laser does not come out in a precise direction; it comes out in all directions.`
