Population Inversions in Lightning Discharges?

LaserFest provides a fitting opportunity to reflect on whether one of the hallmarks of the laser—population inversion—may have long predated its invention. Could these highly unstable and seemingly unnatural phenomena be part of the normal atmospheric process of lightning discharge?
