When a laser first turns on and the gain exceeds threshold, the small amount of laser light intensity allows the upper level population to continue to increase as shown in Figure 19-3. The value of the gain coefficient present in the medium is yo called the unsaturated gain coefficient or small- signal gain coefficient. The intensity present in the cavity increases exponentially until it reaches the saturation intensity value. How is the saturation intensity defined?
