摘要：

As　a　pump　source　for　Ti:　Sapphire　solid-state　lasers,　the　fiber-coupled　green　diode　laser　module　is　critical.　However,　existing　study　findings　are　insufficient　to　meet　the　demands　of　high　brightness　diode　laser　pump　sources.　In　this　paper,　a　high　brightness　green　diode　laser　fiber-coupled　system　based　on　TO-can　diode　lasers　is　designed.　The　FACs　are　installed　within　the　TO-can　diode　lasers.　The　optical　step　as　the　spatial　beam　combining　system　is　made　up　of　the　HR　mirror　and　the　optical　wedge.　We　discussed　the　relationship　between　the　reflected　beam　deflection　angle　and　the　optical　wedge　surface　inclination　angle　under　the　condition　of　different　HR　mirror　inclination　angles.　After　that,　a　strategy　with　appropriate　heat　dissipation　effect　is　obtained　through　thermal　simulation.　Finally,　the　simulation　results　verify　that　couple　18　TO-can　single　emitters　into　a　50μm　core　diameter　and　0.22　numerical　aperture　optical　fiber　with　an　output　power　of　16.9W,　the　fiber　coupling　efficiency　is　98%.　The　brightness　is　5.66　MW/(cm2·Sr)　and　the　module　dimension　is　L　220mm×W　80mm×H　45mm.　©　2022　SPIE.
