Vector Potential Pump

    1. The problem statement, all variables and given/known data
    Prove that the relationship between the dimensionless amplitude a of a wave and the intensity I of the wave is given by:

    2. Relevant equations
    B = curl (A)
    B: Magnetic Field
    A = [mass of electron * c / e ]*a*e^[i*(kx-wt)]
    where k is the wavenumber and is given by: 2pi / wavelength of laser
    I = c*B^2 / (magnetic permeability of free space)
    Hint: div(A) = 0 will give a unique solution for B

    3. The attempt at a solution
    Honestly I do not know where to begin. Take the divergence of the equation of A and find a solution for B? I am not sure.
