Answer #1

from Rayleigh criteria

x = 1.22 * L / D = 1.22* 560* 10^-9 / 2.34

x = 2.92 * 10^-7 rad

x = 1.674* 10^-5 deg

    A telescope can be used to enlarge the diameter of a laser beam and limit diffraction spreading. The laser beam is sent through the telescope in opposite the normal direction and can then be projected onto a satellite or the Moon. If this is done with the Otto Struve telescope, producing a 2.102.10 m diameter beam of 613613 nm light, what is the minimum angular spread of the beam? minimum angular spread: Neglecting atmospheric effects, what is the size of...
