5. Why don't you see your laser point when you shine it on the moon from here on earth? Let's say that you even have a green (534 nm) laser pointer that can output the labeled, normal 5 mW. What will be the size of the laser point and its intensity on the moon if the laser starts with a width of 1.0 mm?

A 3 mW red ( = 670 nm) laser pointer produces a 2 mm diameter spot on a screen. a) If we place a f = 1cm lens before the screen, and the radius of curvature of the wavefront reaching the lens is 2 m, find the waist of the focused light. b) The intensity of the light at the center of the beam is given by Imax= 2P/πw2(in W/m2). Calculate the maximum intensity at the focal point. c) If...

5. You illuminate a Michelson interferometer with a helium-neon laser. The interference pattern is uniform - there are no stripes or rings. The laser has a wavelength of 632.8 nm. You move the mirror on the translation stage until the intensity of the interferometer output is maximum. You measure that the output intensity is 10 = 0.80 mW/cm . Then, you move the mirror on the translation stage by some additional amount Ar. You observe that the output intensity drops...
