In a He-Ne laser system the starting intensity is 0.1 picowatts with a gain coefficient of 0.1 (1/cm). If R1 = .98 and R2 = .99, with a cavity length of 50 cm, what is the intensity of the beam inside AND outside the cavity after five round trips? Assume the starting beam is from the second mirror R2, and that there is no saturation mechanism involved.
