Abstract
Optical excitation of a new F center/CN- defect complex in CsCl produces --instead of any electronic emission-- a highly efficient 5 band vibrational emission around ~4.8 µm (~0.25 eV), involving the 5 lowest states of the CN- anharmonic oscillator. Pulsed laser excitation shows that the energy transfer from the excited F electron occurs mainly at 1 eV into the 4th CN- level producing a sequence of Δn=1 population inversions and emissions with great potential for laser application.
