Phakathi kwazo, i-laser diode bar igqamile ngenxa yemveliso yayo ephezulu yamandla, ubume obubambeneyo, kunye nolawulo olubalaseleyo lwe-thermal, iyenza ibe yinxalenye ebalulekileyo kumacandelo anjengokusetyenzwa kwemizi-mveliso, ubuhle bezonyango, imithombo yempompo, kunye nophando lwezenzululwazi.

1. Yintoni iBar yeDiode yeLaser?

I-laser diode bar, eyaziwa ngokuba yi-laser diode array, sisixhobo se-laser semiconductor esiphezulu samandla esenziwe ngokudibanisa iiyunithi ezininzi ze-laser-emitting kwi-substrate enye eqhelekileyo. Ngokuqhelekileyo, iyunithi nganye ekhuphayo imalunga ne-100 micrometers ububanzi, ngelixa ububanzi bubonke bebar bunokuvela kwiimilimitha ezininzi ukuya kwiisentimitha. Ngenxa yokuba iiyunithi ezininzi ze-laser zicwangciswe ecaleni, imivalo ye-laser diode inokuhambisa amandla aqhubekayo okanye atyhuliweyo ukusuka kumashumi eewatts ukuya ngaphezulu kwekilowatt.

2. Iimpawu eziphambili

① Uxinano lwaMandla aphezulu

Imivalo ye-laser diode idibanisa ii-emitters ezininzi kwindawo ehlangeneyo ukuhambisa amandla aphezulu kakhulu, izenza zilungele usetyenziso olufuna isixa esikhulu samandla.

② Ulawulo olugqwesileyo lwe-Thermal

Ubume bebha buhambelana nobugcisa bokupakisha obahlukeneyo, obufana ne-AuSn (igolide-tin), yonke i-indium, kunye nokupakishwa kwe-hybrid, okwandisa ukutshatyalaliswa kobushushu, ukwandisa ixesha lokuphila kwesixhobo, kunye nokuqinisekisa ukusebenza okuzinzileyo kwexesha elide.

③ Ubume beWaveleng obunokwenziwa ngokwezifiso

Ngokuxhomekeke kwisicelo, imivalo ye-laser diode inokuthi yenzelwe ubude obuhlukeneyo bokusebenza, njenge-808 nm, 915 nm, 940 nm, kunye ne-976 nm. Ukulungelelaniswa kwe-wavelength ekhethekileyo kukwakhona ukuhlangabezana neemfuno ezithile zezinto ezahlukeneyo kunye neenkqubo.

④ Ukubunjwa kweBeam eguquguqukayo

Nangona umgangatho we-beam yee-laser diode bar ngokubanzi ungaphantsi kune-mode-mode lasers, amacandelo okukhanya afana ne-lens arrays, i-fiber coupling, kunye neenkqubo ze-lens ezincinci zingasetyenziselwa ukungqubana okanye ukugxila kwi-beam, ukuphucula ukudibanisa kunye nokuguquguquka kwizicelo zenkqubo.

3. Iinkalo zeSicelo

① Imveliso yoShishino

Isetyenziswe kwi-welding yeplastiki, unyango lobushushu lwesinyithi, ukucocwa kwelaser, kunye nokumakishwa, imivalo ye-laser diode inikezela ngomlinganiselo ogqwesileyo weendleko zokusebenza kwiinkqubo ezifuna imithombo ye-laser enamandla kakhulu.

② Ezonyango kunye nobuhle

Ngokomzekelo, i-808 nm laser diode bar isetyenziswa ngokubanzi kwizixhobo zokususa iinwele ze-laser. Banikezela ngamandla aphezulu kunye nobunzulu bokungena obuphakathi, ukutshabalalisa ngokufanelekileyo iifollicle zeenwele ngaphandle kokonakalisa izicubu ezijikelezileyo.

③ Imithombo yempompo yeeFayibha iiLaser

Kwiinkqubo ze-laser fiber zamandla aphezulu, imivalo ye-laser diode isoloko isetyenziswa njengemithombo yempompo ukuze ivuyise i-Yb-doped okanye i-Er-doped fibers, idlala indima ebaluleke kakhulu ekwakheni iinkqubo ze-laser zamandla aphezulu.

④ Uphando lwezeNzululwazi kunye noKhuselo

Imivalo ye-laser diode ikwasetyenziswa ngokubanzi kubuchwephesha obuphezulu obufana novavanyo lwefiziksi yamandla aphezulu, i-LiDAR, kunye nonxibelelwano lwe-laser, ngenxa yemveliso yazo ezinzileyo kunye neepropathi ezinokwenziwa ngokwezifiso.

Njengoko iimfuno zokusebenza kweenkqubo ze-laser ziqhubeka nokunyuka, imivalo ye-laser diode iguqukela kumandla aphezulu, ukuthembeka okukhulu, izinto ezincinci zeefom, kunye neendleko eziphantsi. Njengenxalenye ephambili kwiinkqubo zokusetyenziswa kwelaser, imivalo ye-laser diode yamkelwa ngokubanzi kuwo wonke amasimi obuchwepheshe obuphezulu. Ngenkqubela phambili yetekhnoloji eqhubekayo kunye nekhonkco leshishini elikhulayo, iibar diode ze-laser kulindeleke ukuba zonwabele amathemba abanzi entengiso kwaye zithathe indima enobuchule ngakumbi kwixesha elizayo.
