The semi classical theory of laser as developed by Willis Lamb and coworkers several decades ago explains a large number of laser phenomena particularly in gaseous phase. In this theory it has been shown that, whenever we plot normalized population difference versus axial coordinates, there appears dips or holes at regular intervals at particular positions along the laser axis. These holes represent the depletion of population inversion thereby meaning the reduction of laser beam intensity. These holes are known as spatial holes. These holes are always present in laser originating from a Fabry-Perot cavity and are not welcome in the operation of high power laser. In the present work, we analyzed the phenomenon of spatial hole burning in the light of some non-physics context.
