A laser (wavelength fo = 633 nm) is generating a Gaussian beam with 0.1 mm beam waist (2wo).

(1) Find the beam's divergence angle and depth of focus

(2) What will be its diameter when it reaches Moon? Earth-Moon distance = 3.5×105 km. Search "Lunar Ranging Project" if you got interested. We DID land on moon.

(3) Find the radius of curvature of the phasefront at z = 0, zo, and 2zo ?

(4) What will be the intensity (in W/cm2) at the beam center (r = 0, z = 0) and a point along the axis (r = 0, z = zo)?
