6) Consider a laser of which all mirrors are 100% reflective except for the output mirror which reflects 96% of the output power and absorbs 1.25%. The gain medium has a

length of 25cm and a small signal unsaturated gain at the transition line center of 0,005/cm with a saturation intensity of 5W/cm². What is the output intensity if the laser has (a) a linear cavity with homogenously broadened gain medium; (b) a ring laser cavity with a homogenously broadened gain medium.
