A pointer laser has an average output power of 0.9 mW and a beam diameter of 1.2 mm.

(a) What is the force exerted by the laser beam on a perfectly reflecting surface ?

(b) Is this force much larger, smaller, or about the same compared to the weight of a 0.1 gram drop of water ( 1x10^-4x9.8 = 9.8x10^-4 Newton )

(c) What is the rms electric field produced by this laser ?

a. Consider a laser radar emitting a Gaussian beam of diameter 20 cm with a wavelength of 2.1 μm. At distances of 50, 500, 5000, and 50,000 meters, what is the focused beam diameter, and what is the depth of field? Remember the depth of field is twice the Rayleigh range of the waist diameter. Remember that in some cases the solution may be impossible. Also re- member that there may be two solutions, and it makes sense to pick...
