For the general case of nonmonochromatic light, the transverse beam profile must be expected to depend upon time, and the same will be true for the energy density w and the density of AM j . This time dependence arises from the terms with n = n in the double summation over frequency values. 2 Spin of Rotating Polarization A linear polarization vector that performs a rotation with angular frequency Ω can be described as  1 e(z, t) = √ e+ e−iΩ(t−z/c) + e− eiΩ(t−z/c) . 2 (74) As a function of time, the polarization rotates in the positive direction with angular frequency Ω in the transverse plane.

The density of AM in the z-direction to first order in δ can be obtained by using equation (51), with the transverse momentum given by equation (52). The zcomponents of the fields are related to the transverse parts by equation (47). Then the expression (53) for the separation of the density of AM into the sum jz = l + s is still valid, where in the present nonmonochromatic case, the complex electric field and the complex transverse vector potential in equations (70) and (71). For the general case of nonmonochromatic light, the transverse beam profile must be expected to depend upon time, and the same will be true for the energy density w and the density of AM j .
