A cylindrical rod of some laser material `5xx10^-2`m long and `10^-2m` in diameter contains `2xx10^25` ions per `m^3`. If on excitation all the ions are in the upper energy level and de-excite simultaneously emitting photons in the same direction , calculate the maximum energy contained in a polse of radiation of wavlength `6.6xx10^-7`m. If the pulse lasts for `10^-7s`, calculate the average power of the laser during the pulse.
