Fiber-taper tellurite coupled L-band Er 3+ -doped tellurite glass microspheres lasers were fabricated. The doped glasses were prepared using a gold crucible in an electric heated furnace. Bulk samples were used for spectroscopic characterization and other property measurements. The emission cross section spectrum was calculated from the absorption cross section spectrum and emission spectrum. The microsphere laser was demonstrated successfully.
