Problem 2 (It) points}. A laser gain medium contains 1 mole of laser atoms, and all are in the excited state. A single photon traverses the medium in 109 seconds initiating stimulated emissionat the laser wavelength of A = 633 nm in all the atoms resulting in a single 1-mm-diameter laser pulse. 'What is the irradienee of this pulse
