Abstract :
Under irradiation of a pure solid CO sample at low temperature by a CW CO laser beam,13C16O,12C18O and13C18O molecules are excited to high vibrational levels, up to 
, and a strong population inversion is observed. The12C16O molecules are pumped to the 
level by laser line absorption in the low frequency phonon sideband, and the vibrational energy is subsequently transferred to the other isotopes. Quantum yield, efficiency, and heat release are discussed to clarify the mechanism.
