Question

5. An argon-ion laser (à 488.0 nm) is emitting a "pure" TEMO0 transverse mode. Estimate the area of coherence of the beam at a distance of 10.0 meters from the output coupler. Assume the initial radius of the beam o, 2.00 mm and utilize the appropriate equation(s) from page 19 of your Chapter 4 notes. How does this result compare to the result of Problem #4?
