Abstract：

This　paper　proposes　a　multi-stage　cooling　system　based　on　TEC　(Thermo　Electric　Cooler),　vapor　chamber,　heat　sink　and　fan　for　the　high　power　compact　laser　diode　in　the　high　temperature　and　mobility　environment.　Using　Flow　Simulation　and　ANSYS　software,　the　temperature　field　and　thermal　stress　of　the　multi-stage　cooling　system　under　steady　state　are　discussed　respectively,　and　the　multi-stage　cooling　system　model　is　optimized　according　to　the　two　simulation　results　and　the　physical　test　is　carried　out.　The　results　show　that　the　designed　cooling　system　can　achieve　a　continuous　and　stable　output　of　more　than　70W　from　the　laser　at　both　room　temperature　of　20°C　and　high　temperature　of　55°C.　©　2022　SPIE.
