A 2.3 milliwatt HeNe laser beam is focused using a DCX (focal length 160mm). The spot size area is 6.7 x 10^-7 cm^2. Determine the spot radius and the divergence of the laser beam.
Added by Alexander H.
Step 1
7 x 10^-7 cm^2. We know that the spot size area is related to the beam waist radius (w0) by the equation: Spot size area = πw0^2/4 Rearranging this equation, we get: w0 = 2√(Spot size area/π) Substituting the given values, we get: w0 = 2√(6.7 x 10^-7/π) = 1.03 Show more…

3.)The beam of a laser with power 1 GW, wavelength 500 nm and cross-section 0.5 cm2 is focused by a lens with a focal length of 10 cm and a diameter of 2 cm. Calculate the amplitude of the electric field in center of the focal region. Assess focal spot sizes along the axis and perpendicular to the axis.

The radiation emitted by a laser spreads out in the form of a narrow cone with circular cross section. The angle $\theta$ of the cone (see Fig. $34-20$ ) is called the full-angle beam divergence. An argon laser, radiating at $514.5 \mathrm{~nm}$, is aimed at the Moon in a ranging experiment. If the beam has a full-angle beam divergence of $0.880$ \murad, what area on the Moon's surface is illuminated by the laser?
