  The spectral properties associated with laminar, anti-parallel reconnection
are examined using a 2.5D kinetic particle in cell (PIC) simulation. Both the
reconnection rate and the energy spectrum exhibit three distinct phases: an
initiation phase where the reconnection rate grows, a quasi-steady phase, and a
declining phase where both the reconnection rate and the energy spectrum
decrease. During the steady phase, the energy spectrum exhibits approximately a
double power-law behavior, with a slope near -5/3 at wavenumbers smaller than
the inverse ion inertial length, and a slope steeper than -8/3 for larger
wavenumbers up to the inverse electron inertial length. This behavior is
consistent with a Kolmogorov energy cascade and implies that laminar
reconnection may fundamentally be an energy cascade process. Consistent with
this idea is that the reconnection rate exhibits a rough correlation with the
energy spectrum at wave numbers near the inverse ion inertial length. The 2D
spectrum is strongly anisotropic with most energy associated with the wave
vector direction normal to the current sheet. Reconnection acts to isotropize
the energy spectrum, reducing the Shebalin angle from an initial value of 70
degrees to about 48 degrees (nearly isotropic) by the end of the simulation.
