Question

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?

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 × 10^16/m^3 in the upper laser level and 4 × 10^15/m^3 in the lower laser level. If a very low-power probe beam of intensity I0 is transmitted into the gain medium then what would be the measured ratio of I/I0, where I is the output beam intensity after traversing the medium?

Step 1

The main concept is to determine the ratio of the output beam intensity (I) to the input probe beam intensity (Io) after the probe beam traverses the gain medium of the argon ion laser. Show more…

Please write the main concept/main expression in the first step, then solve it; otherwise, I will downvote. Please don't write the given data in the first step. 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 x 10^1/m^3 in the upper laser level and 4 x 10^15/m^3 in the lower laser level. If a very low-power probe beam of intensity Io is transmitted into the gain medium, then what would be the measured ratio of I/Io, where I is the output beam intensity after traversing the medium?
