Assume that you want to bounce a laser beam off the Moon. Assume the laser beam is TEM9,0 and that the Moon is a distance of 3.8 · 10$ meters from Earth. Calculate the following. (a) Assume that the initial beam waist of a CO, laser running on the 10.6 µm line is 15 cm. How large is the beam waist when the beam hits the Moon? What is the radius of curvature? (b) Assume that the initial beam waist of a CO, laser running on the 10.6 µm line is 1.5 meters. How large is the beam waist when the beam hits the Moon? What is the radius of curvature? (c) Repeat part (a) for an excimer laser operating at 254.0 nm; use the same beam waist. |(d) Repeat part (b) for an excimer laser operating at 254.0 nm; use the same beam waist. (e) From your answers to parts (a-d), speculate on what kind of laser and what type of associated optical system you would want to use in order to optimally bounce a laser beam off the Moon.
