Abstract：

Single　wavelength　laser　sources　used　for　pumping　lasers　demonstrate　poor　resistance　to　environmental　factors.　Therefore,　a　method　for　employing　an　amplified　spontaneous　emission　(ASE)　light　source　for　pumping　thulium　ion　(Tm3+)　doped　silica　microsphere　(TDSM)　lasers　is　proposed.　The　ASE　source　emits　non-polarized　light　with　a　broad　bandwidth.　When　using　ASE　light,　there　is　always　a　wavelength　group　that　resonates　with　the　high-Q　microsphere　to　adaptively　couple　into　TDSM　and　excite　the　Tm3+　ion.　The　ASE　source　resists　the　resonance　wavelength　mismatch　owing　to　the　variation　of　pump　light　polarization　caused　by　vibration　and　the　variation　induced　by　temperature　change.　With　ASE　light　pumping,　we　demonstrated　the　generation　of　2　μm　whispering　gallery　modes　(WGMs)　laser　with　a　very　low　threshold.　©　2019　Elsevier　B.V.
