    Finite-element calculations of the population mechanisms in diode-end-pumped 3-µm Er:YLF lasers demonstrate that interionic-upconversion-induced multiphonon relaxations significantly increase heat generation, temperature gradients, and thermal lensing. This explains rod fracture above 1 W of output power.
