1 An argon ion laser (as shown in Figure 10-30) operating at 488.0 nm with a gain-region length of 0.3 m is determined to have a population density of $1 \times 10^{16}/m^3$ in the upper laser level and $4 \times 10^{15}/m^3$ in the lower laser level. If a very low-power probe beam of intensity $I_0$ is transmitted into the gain medium then what would be the measured ratio of $I/I_0$, where $I$ is the output beam intensity after traversing the medium?
