High Frequency EMW From Laser

When we reverse the direction of circular motion of the particles, in the post "It's All Fluorescence Outside, Inside" dated 29 Jul 2015,


The \(E\) field lines looking into the direction of of propagation, along \(OP\),


This however, is an EMW, where

\(B=-i\cfrac{\partial\,E}{\partial x}\)

If both directions of rotation are equally probable then, a laser should also be radiating high frequency EMW.  Both light and EMW outputs share the input power.
