Abstract
We present the first detailed theoretical analysis of multi-color continuous wave lasing in Tm-doped tellurite spherical microresonators with whispering gallery modes pumped at a wavelength of 792 nm. The numerical model is based on solving a system of equations for intracavity field amplitudes and rate equations using the parameters of Tm-doped tellurite glass measured in the previous experiments. All fundamental whispering gallery modes in the gain bands are taken into account. We demonstrate diagrams of generation regimes depending on Q-factors and pump power, which show a possibility of single-color lasing at a wavelength of ~1.9 μm, two-color lasing at wavelengths of ~1.9&1.5 μm and at ~1.9&2.3 μm, and three-color lasing at wavelengths of ~1.9&1.5&2.3 μm. Such microlasers can play a significant role in sensing applications.
