From　Er3+/Tm3+　co-doped　tellurite　glass　microspheres,　simultaneous　laser　oscillation　at　1.9　mu　m,　and　green　and　red　fluorescence　emissions　with　three　photons　upconversion　luminescence　were　obtained.　The　microsphere　was　pumped　by　a　low-cost　1550　nm　broadband　amplified　spontaneous　emission　source　instead　of　a　bulky　and　expensive　tunable　laser.　It　as　a　non-polarized　light　provided　a　wide　wavelength　range　and　the　multiple　wavelengths　resonant　absorption　was　obviously　observed　from　the　transmission　spectra.　The　use　of　broadband　source　made　the　entire　microsphere　laser　more　adaptively　stable　to　withstand　the　vibration　interference　and　temperature　variations.　The　coupled　threshold　power　was　as　low　as　1.5　mW.　It　was　demonstrated　that　the　Er3+　ions　acted　as　sensitizers　to　efficiently　absorb　the　pump　photons　and　transfer　energy　to　Tm3+　ions.　Therefore,　this　approach　would　have　potential　applications　in　optical　fiber　lasers,　sensors　and　lighting　devices.
