Falanqaynta Qoto-dheer ee Habka Dahaarka Laser-ka: Mabaadi'da, Kala-soocidda iyo Xulashada Agabka
Tiknoolajiyadda dahaarka laysarka waxay matalaysaa farsamo injineernimo oo dusha sare ah. Mabda'eedu wuxuu ku jiraa in si taxaddar leh loogu meeleeyo walax dahaar ah oo la doortay dusha sare ee substrate-ka qaabab buuxin oo kala duwan. Maadaama iftiinka laysarka tamar sare leh uu shucaaciyo aagga, ma aha oo kaliya in walaxda dahaarka ay dhalaalto, laakiin sidoo kale lakab khafiif ah oo dusha sare ee substrate-ka ah ayaa isku mar dhalaala. Iyada oo loo marayo adkeynta degdega ah, dahaarka dusha sare oo leh heer aad u hooseeya oo milmi ah ayaa la sameeyaa. Dahaarkani wuxuu sameeyaa isku xidh bir ah oo leh walaxda substrate-ka, taas oo muhiim ah maadaama uu si weyn u wanaajin karo sifooyin badan oo dusha sare ee substrate-ka ah. Tusaale ahaan, si weyn ayuu u hagaajin karaa iska caabbinta xirashada, isagoo u oggolaanaya qaybaha inay u adkaystaan isku dhac badan; kor u qaadida iska caabbinta daxalka, ilaalinta agabka weerarada kiimikada; kor u qaadida iska caabbinta kulaylka iyo iska caabbinta oksaydhka, taasoo awood u siinaysa qaybaha inay ka shaqeeyaan jawi heerkul sare iyo oksaydh; iyo xitaa wax ka beddelka sifooyinka korontada.
Sida ku xusan nooca walxaha dahaarka laysarka iyo sida ay ula jaanqaado iftiinka laysarka, teknoolojiyada dahaarka laysarka ee caadiga ah ayaa loo kala saari karaa. Tiknoolajiyada dahaarka laysarka ee quudinta budada isku-dhafan ayaa badanaa adeegsata laysarka wax soo saarka semiconductor fiber iyo nooca gaaska qaada ee disc-ga. Madaxa dahaarka wuxuu leeyahay naqshad goob wareegsan oo leh wax soo saar iftiin dhexe iyo quudinta budada wareegsan ama quudinta budada badan ee ku wareegsan iftiinka, oo ay weheliso kanaal gaas oo ilaalin ah oo gaar ah. Inta lagu jiro habka dahaarka, laysarka budada, laysarka, iyo socodka gaaska ilaalinta ayaa isku soo ururaya hal dhibic, iyagoo abuuraya barkad dhalaalaysa oo ku taal barta diiradda. Marka madaxa dahaarka iyo shaqada ay is barbar socdaan, dahaar joogto ah oo tayo sare leh ayaa si tartiib tartiib ah loogu sameeyaa dusha sare ee shaqada. Tiknoolajiyada dahaarka laysarka quudinta budada Paraxial, oo sidoo kale loo yaqaan tiknoolajiyada dahaarka laysarka quudinta budada dhinaca, waxay leedahay astaamo u gaar ah oo ku jira farsamooyinka isku xidhka budada - quudinta iyo iftiinka -. Tiknoolajiyada dahaarka laysarka xawaaraha sare leh, oo mararka qaarkood loo yaqaan tiknoolajiyada dahaarka laysarka xawaaraha sare leh, waxay diiradda saartaa gaaritaanka heerarka dahaarka ee degdega ah iyadoo la ilaalinayo tayada dahaarka. Tiknoolajiyadda dahaarka laser-ka ee xawaaraha sare leh waxay isticmaashaa agab qaabaysan oo silig ah, iyadoo soo bandhigaysa hab ka duwan marka loo eego hababka dahaarka ee ku salaysan budada. Mid kasta oo ka mid ah hababkan kala-soocidda waxay leedahay xaalado codsi iyo faa'iidooyin u gaar ah, taasoo ka dhigaysa dahaarka laser-ka mid aad u kala duwan oo la qabsan kara dhinacyada warshadaha kala duwan.
