In Laser beam, the photons are in phase, the resultant intensity is given in terms of amplitude ‘a’ and number of photons ‘n’ is proportional to na n 2 a n 2 a 2 n a 2

In laser much number of photons are in phase with each other, the amplitude of the resulting wave becomes na and hence intensity is n²a²
(c) n²a²
