1. Yintoni iLaser Diode Bar?

Ibha yedayidi yelaser, eyaziwa ngokuba yi-laser diode array, sisixhobo selaser se-semiconductor esinamandla aphezulu esenziwe ngokuhlanganisa iiyunithi ezininzi ezikhupha ilaser kwi-substrate enye eqhelekileyo. Ngokwesiqhelo, iyunithi nganye ekhuphayo imalunga ne-100 micrometer ububanzi, ngelixa ububanzi bebha bunokwahluka ukusuka kwiimilimitha ezininzi ukuya kwiisentimitha. Ngenxa yokuba iiyunithi ezininzi zelaser zicwangciswe ecaleni, iibha zedayidi yelaser zinokuhambisa amandla aqhubekayo okanye ashukumayo ukusuka kwi-watts ezilishumi ukuya kwi-kilowatt engaphezulu kwe-kilowatt.

2. Iimpawu eziphambili

① Uxinano lwamandla aphezulu

Iibha ze-laser diode zidibanisa ii-emitters ezininzi kwindawo encinci ukuze zinike amandla aphezulu kakhulu, nto leyo ezenza zilungele ukusetyenziswa kwamandla amaninzi.

② Ulawulo oluGqwesileyo lobushushu

Ulwakhiwo lwebha luhambelana netekhnoloji ezahlukeneyo zokupakisha, ezifana ne-AuSn (igolide-tin), i-all-indium, kunye nokupakisha okuxutyiweyo, okuphucula ukusasazwa kobushushu, ukwandisa ubomi besixhobo, kunye nokuqinisekisa ukusebenza okuzinzileyo kwexesha elide.

③ Ubude beWavelength obunokwenziwa ngokwezifiso

Ngokuxhomekeke kwisicelo, iibha ze-laser diode zinokuyilwa kwiiwavelengths ezahlukeneyo zokusebenza, ezifana ne-808 nm, 915 nm, 940 nm, kunye ne-976 nm. Ukulungiswa kwewavelength ekhethekileyo kukwafumaneka ukuhlangabezana neemfuno ezithile zezixhobo kunye neenkqubo ezahlukeneyo.

④ Ukubumba iBeam eguquguqukayo

Nangona umgangatho wemitha ye-laser diode bars uphantsi kakhulu kunowe-single-mode lasers, izinto ezibonakalayo ezifana ne-lens arrays, i-fiber coupling, kunye neenkqubo ze-micro-lens zingasetyenziselwa ukulinganisa okanye ukujolisa imitha, nto leyo ephucula ukuhlanganiswa kunye nokuguquguquka kwizicelo zenkqubo.

3. IiNdawo zokufaka izicelo

① Ukwenziwa kweMveliso yeShishini

Iibha ze-laser diode zisetyenziswa ekudibaniseni ngeplastiki, ekunyangweni kobushushu besinyithi, ekucoceni nge-laser, nasekuphawuleni, zibonelela ngomlinganiselo ogqwesileyo weendleko-ukusebenza kwiinkqubo ezifuna imithombo ye-laser enamandla aphezulu.

② Ezonyango kunye nobuhle

Umzekelo, iibha ze-laser diode ze-808 nm zisetyenziswa kakhulu kwizixhobo zokususa iinwele nge-laser. Zinika amandla aphezulu kunye nobunzulu obuphakathi bokungena, zitshabalalisa ngempumelelo iifollicle zeenwele ngaphandle kokonakalisa izicubu ezingqongileyo.

③ Imithombo yeMpompo yeFiber Lasers

Kwiinkqubo ze-laser ezinefayibha enamandla aphezulu, iibha ze-laser diode zihlala zisetyenziswa njengemithombo yepompo yokuvuselela iifayibha ezine-Yb okanye ezine-Er, zidlala indima ebalulekileyo ekwakheni iinkqubo ze-laser ezinamandla aphezulu.

④ Uphando lwezeNzululwazi kunye noKhuselo

Iibha ze-laser diode zikwasetyenziswa kakhulu kubuchwepheshe obuphambili obufana novavanyo lwefiziksi olunamandla aphezulu, i-LiDAR, kunye nonxibelelwano lwe-laser, ngenxa yemveliso yazo ezinzileyo kunye neempawu ezinokwenziwa ngokwezifiso.

Njengoko iimfuno zokusebenza kweenkqubo ze-laser ziqhubeka nokunyuka, ii-laser diode bars ziyaguquka ziye kumandla aphezulu, ukuthembeka okukhulu, izinto ezincinci zemo, kunye neendleko eziphantsi. Njengenxalenye ephambili kwiinkqubo zesicelo se-laser, ii-laser diode bars ziyamkelwa ngokubanzi kwiinkalo zobuchwepheshe obuphezulu. Ngokuqhubeka kwezobuchwepheshe kunye nochungechunge lweshishini olukhula ngakumbi, ii-laser diode bars kulindeleke ukuba zonwabele amathuba emarike abanzi kwaye zithathe indima enobuchule ngakumbi kwixesha elizayo.
