Abstract:
In recent years solid state lasers, operating at the 1.5 μm wavelength region, have received much attention for fiber-optic communication systems of metropolitan and local area networks since the highest data rates are achieved using silica glass fibers with minimal transmission losses near this wavelength. In this spectral region the most suitable active ion among the trivalent rare-earth (RE3+) ions is Er3+ with the 4f11 electronic configuration of the ground state. In various crystalline fields it reveals a rich set of energy levels with multiple possible lasing transitions and channels of excitation energy nonradiative transfer.
