Step 1
The waist size of 0.25 mm corresponds to a beam radius of 0.125 mm. The radius of curvature can be calculated using the formula R = L/2, where L is the distance between the mirrors (30 cm = 300 mm). R = 300 mm / 2 R = 150 mm Show more…

Design a mirror arrangement so that light from a laser pointer will travel in exactly the opposite direction after it reflects off the mirror(s), even if you change the direction the laser pointer is pointing.
Consider a resonator consisting of a plane mirror and a concave mirror of radius of curvature $R$ (see Fig. 20.26). Assame $\lambda=1 \mu \mathrm{m}, R=100 \mathrm{~cm}$ and the distance between the 2 mirrors to bo $50 \mathrm{~cm}$. Calculate the spot size of the Gaussian beam.
