A He-Ne laser ( wavelength= 632.8nm) is constructed from a cavity that is 0.34m long, a fully reflecting

mirror of radius RL = 30m , and an output mirror of radius RR = 10m.

a Make a rough sketch of the system.

b Determine the location of the beam waist inside the cavity i.e. where is z = 0?

c Determine the beam waist, wo.
