Abstract：

Aiming　at　the　development　trend　of　high-power　semiconductor　devices　and　multiple　short　laser　diode　array　components　integrated　structure　applied　to　a　single　all-fiber　structure　optical　fiber　lasers　and　lack　of　related　heat　control　theory,　the　finite　element　software　ANSYS　is　used　to　simulate　the　thermal　properties　of　a　high　beam　quality　laser　diode　arrays　based　on　the　standard　heat　conduction　heat　sink　structure.　By　changing　the　spacing　and　the　number　of　light-　emitting　unit　of　the　light-emitting　elements　in　the　array,　the　traditional　structure　of　high　fill　factor　cm-bar　array　is　transitioned　to　short-　or　multi-unit　integrated　device　thermal　model.　A　theoretical　basis　is　provided　for　the　design　and　high-performance,　long　life　heat　of　this　new　high　beam　quality　device　by　its　hot　characteristics.
