Heine H. Hansen M.D. hindered by the fact that the lower laser level is the ground state in this case, thus impeding population inversion. UV lasers hence mainly rely on transitions in ions and molecules. The same holds true for the infrared spectral range, as the photon energies related to infrared transitions are muc
