Lumispot Tech siv cov txheej txheem ntim khoom uas siv AnSn solder es tsis siv indium solder ib txwm muaj los daws cov teeb meem ntsig txog kev qaug zog thermal, electromigration, thiab kev hloov pauv hluav taws xob-thermal los ntawm indium solder. Los ntawm kev siv AuSn solder, peb lub tuam txhab lub hom phiaj yog txhim kho kev ntseeg tau ntawm cov khoom thiab lub neej ntev. Qhov kev hloov pauv no yog ua tiav thaum ua kom muaj qhov sib nrug ntawm cov khoom sib dhos, ntxiv rau kev txhim kho kev ntseeg tau ntawm cov khoom thiab lub neej ntev.
Hauv cov thev naus laus zis ntim khoom ntawm lub zog siab semiconductor pumped solid-state laser, indium (In) hlau tau raug saws los ua cov khoom siv vuam los ntawm ntau lub tuam txhab thoob ntiaj teb vim nws qhov zoo ntawm qhov melting point qis, kev ntxhov siab vuam qis, kev ua haujlwm yooj yim, thiab kev hloov pauv yas zoo thiab infiltration. Txawm li cas los xij, rau semiconductor pumped solid state lasers nyob rau hauv kev ua haujlwm tas mus li, kev ntxhov siab hloov pauv yuav ua rau kev ntxhov siab ntawm indium vuam txheej, uas yuav ua rau cov khoom tsis ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv qhov kub siab thiab qis thiab ntev pulse dav, qhov tsis ua haujlwm ntawm indium vuam yog qhov pom tseeb heev.
Kev sib piv ntawm kev sim lub neej ceev ntawm lasers nrog cov pob khoom sib txawv
Tom qab 600 teev ntawm kev laus, tag nrho cov khoom encapsulated nrog indium solder tsis ua haujlwm; thaum cov khoom encapsulated nrog kub tin ua haujlwm rau ntau tshaj 2,000 teev nrog yuav luag tsis muaj kev hloov pauv hauv lub zog; qhia txog qhov zoo ntawm AuSn encapsulation.
Yuav kom txhim kho qhov kev ntseeg siab ntawm cov lasers semiconductor muaj zog heev thaum tswj hwm qhov sib xws ntawm ntau yam kev ua tau zoo, Lumispot Tech siv Hard Solder (AuSn) ua ib hom khoom ntim khoom tshiab. Kev siv cov coefficient ntawm thermal expansion matched substrate material (CTE-Matched Submount), kev tso tawm ntawm thermal stress zoo, ib qho kev daws teeb meem zoo rau cov teeb meem kev siv tshuab uas yuav ntsib hauv kev npaj cov hard solder. Ib qho tseem ceeb rau cov khoom siv substrate (submount) kom muaj peev xwm soldered rau lub semiconductor chip yog surface metallization. Surface metallization yog kev tsim ntawm ib txheej ntawm diffusion barrier thiab solder infiltration txheej ntawm qhov chaw ntawm cov khoom siv substrate.
Daim duab kos ntawm lub tshuab electromigration ntawm lub laser encapsulated hauv indium solder
Yuav kom txhim kho qhov kev ntseeg siab ntawm cov lasers semiconductor muaj zog heev thaum tswj hwm qhov sib xws ntawm ntau yam kev ua tau zoo, Lumispot Tech siv Hard Solder (AuSn) ua ib hom khoom ntim khoom tshiab. Kev siv cov coefficient ntawm thermal expansion matched substrate material (CTE-Matched Submount), kev tso tawm ntawm thermal stress zoo, ib qho kev daws teeb meem zoo rau cov teeb meem kev siv tshuab uas yuav ntsib hauv kev npaj cov hard solder.

Kev siv cov thev naus laus zis encapsulation kub-tin tuaj yeem kov yeej cov teeb meem ntawm electromigration thiab electrothermal migration ntawm indium solder.
Kev daws teeb meem los ntawm Lumispot Tech
Hauv cov lasers txuas ntxiv mus lossis pulsed, cov cua sov tsim los ntawm kev nqus ntawm lub twj tso kua mis los ntawm cov laser nruab nrab thiab qhov txias sab nraud ntawm cov nruab nrab ua rau muaj kev faib tawm kub tsis sib xws hauv cov laser nruab nrab, ua rau muaj kev hloov pauv kub, ua rau muaj kev hloov pauv hauv cov ntsuas refractive ntawm cov nruab nrab thiab tom qab ntawd tsim ntau yam teebmeem thermal. Cov thermal deposition hauv cov nruab nrab nce ua rau muaj cov teebmeem thermal lensing thiab thermally induced birefringence nyhuv, uas ua rau muaj qee qhov kev poob hauv lub laser system, cuam tshuam rau kev ruaj khov ntawm lub laser hauv qhov thiab qhov zoo ntawm cov zis beam. Hauv lub laser system khiav tas li, qhov kev ntxhov siab thermal hauv cov zis medium hloov pauv raws li lub zog twj tso kua mis nce. Ntau yam teebmeem thermal hauv lub system cuam tshuam loj heev rau tag nrho lub laser system kom tau txais cov beam zoo dua thiab cov zis muaj zog dua, uas yog ib qho teeb meem uas yuav tsum tau daws. Yuav ua li cas kom zoo inhibit thiab txo qhov thermal nyhuv ntawm cov siv lead ua hauv cov txheej txheem ua haujlwm, cov kws tshawb fawb tau muaj teeb meem ntev, nws tau dhau los ua ib qho ntawm cov chaw tshawb fawb tam sim no.
Nd: YAG laser nrog lub qhov thermal lens
Hauv qhov project ntawm kev tsim cov high-power LD-pumped Nd:YAG lasers, cov Nd:YAG lasers nrog thermal lensing cavity tau daws teeb meem, yog li ntawd lub module tuaj yeem tau txais lub zog siab thaum tau txais lub teeb zoo.
Hauv ib qhov project los tsim ib lub high-power LD-pumped Nd:YAG laser, Lumispot Tech tau tsim lub G2-A module, uas daws tau qhov teeb meem ntawm lub zog qis dua vim yog cov qhov uas muaj thermal lens, uas ua rau lub module tau txais lub zog siab nrog lub teeb ci zoo.
