Q.25.A cylindrical rod of any laser material 102m in diameter and 5 x 10m long contains 2 x 104> ions per ms. If on escalation all the ions are present in the upper energy level and de-axial simutamously emitting photons in the same direction determine the maximum energy contained in a pulse of radiation of wave length 6.6 x 10 m. If the pulse lasts for 107s, find the average power of the laser during the pulse.
