Abstract: The cross relaxation of Tm³⁺ ions (on the ³H₄→³F₄, ³H₆→³F₄ transitions) has been studied in CNGG and YAG laser crystals. The radiationless transfer of energy from Cr³⁺ ions to Tm³⁺ ions has been studied in YAG crystals. The interaction between these ions is shown to be due to dipole-dipole and shorter-range quadrupole-quadrupole mechanisms.
