Find the laser beams electric field amplitude at focal point

Reference no: EM13562388

A 200 MW laser pulse is focused with a lens to a diameter of2.0μm.

A. What is the laser beam's electric field amplitude at the focal point?

B. How does this electric field compare to the electric fieldthat keeps the electron bound to the proton of a hydrogen atom? Theradius of the elctron's orbit is 0.053mnm.
