摘要：

To　study　the　application　of　microstructure　optical　fiber　in　optofluidic　technology,　the　HC-PCF　with　carbon　tetrachloride　(CCl4)　was　filled　and　pumped　with　a　1064　nm　pulsed　laser　to　generate　the　stimulated　Raman　scattering.　By　collapsing　the　cladding　holes,　CCl4　can　be　filled　only　in　the　core　of　the　1.8　m　long,　10　μm　core　diameter　HC-PCF　by　capillary　forces　and　external　pressures.　The　light　is　guided　by　total　internal　reflection　since　the　effective　refractive　index　of　cladding　air　holes　(about　1.1)　is　lower　than　CCl4　(about　1.45).　The　1064　nm　pump　laser　has　a　repetition　rate　of　200　kHz,　a　pulse　width　of　186　ps　and　a　tunable　output　power　of　0~1　W.　Two　orders　of　Stokes　line　are　generated　at　1118　nm　and　1172.3　nm.　By　adjusting　the　pump　power,　the　corresponding　peak　power　of　first-order　Raman　threshold　is　0.94　kW.　Results　show　that　the　microstructure　optical　fiber　is　a　good　carrier　for　optofluidic　technology.　©　2015,　Beijing　University　of　Technology.　All　right　reserved.
