Codsiga aasaasiga ah ee farsamaynta laysarka tobankii sano ee la soo dhaafay waxay ku jirtay walxo bir ah, oo ay ku jiraan goynta, alxanka, iyo xidhitaanka. Si kastaba ha ahaatee, goobta ayaa ku sii fideysa agabka aan birta ahayn sida dunta, dhalooyinka, balaastikada, polymers, iyo ceramics. Mid kasta oo ka mid ah qalabkani wuxuu furaa fursado warshado kala duwan, in kasta oo ay hore u dejiyeen farsamooyinka farsamaynta (Yumoto et al., 2017).

Muraayada, oo leh codsiyadeeda ballaadhan ee warshadaha sida baabuurta, dhismaha, iyo elektiroonigga, waxay u taagan tahay aag muhiim ah oo farsamaynta laysarka. Hababka goynta dhalooyinka dhaqameed, kuwaas oo ku lug leh daawaha adag ama qalabka dheeman, waxaa xaddiday waxtarka hooseeya iyo geesaha qallafsan. Taas bedelkeeda, goynta laysarka waxay bixisaa beddelka hufan oo hufan. Tani waxay si gaar ah uga caddahay warshadaha sida wax soo saarka casriga ah, halkaas oo goynta laser loo isticmaalo daboolka muraayadaha muraayadaha iyo shaashadaha bandhiga waaweyn (Ding et al., 2019).

Codsiyada kala duwan ee ku salaysan mawjadaha dhererka
Doorashada mowjadda dhererka layserku maaha mid aan sabab lahayn laakiin waxay aad ugu xidhan tahay alaabta walxaha iyo natiijada la rabo. Tusaale ahaan, laysarka UV (oo leh mawjadaha dhaadheer ee gaaban) waxay aad ugu fiican yihiin xardho sax ah iyo micromachining, sababtoo ah waxay soo saari karaan tafaasiil fiican. Tani waxay ka dhigaysaa inay ku habboon yihiin warshadaha semiconductor iyo microelectronics. Taas bedelkeeda, laysarka infrared-ka ayaa aad ugu waxtar badan farsamaynta walxaha dhumuc weyn sababtoo ah awooddooda qoto-dheer ee qoto-dheer, iyaga oo ku habboon codsiyada warshadaha culus. (Majumdar & Manna, 2013) .Si la mid ah, lasers cagaaran, oo sida caadiga ah ku shaqeeya mowjadda dhererka 532 nm, waxay helayaan niche ee codsiyada u baahan saxnaanta sare leh saamaynta kulaylka ugu yar. Waxay si gaar ah waxtar ugu leeyihiin microelectronics ee hawlaha sida qaabaynta wareegga, codsiyada caafimaadka ee hababka sida xinjirowga dhiigga, iyo qaybta tamarta la cusboonaysiin karo ee soo saarista unugyada cadceedda. Mawjadaha gaarka ah ee leysarka cagaaran ayaa sidoo kale ka dhigaya kuwo ku habboon calaamadaynta iyo xaradhka alaabada kala duwan, oo ay ku jiraan balaastikada iyo biraha, halkaasoo la rabo isbarbardhigga sare iyo dhaawaca ugu yar. Laqabsigan leysarka cagaaran wuxuu hoosta ka xariiqayaa muhiimada xulashada mawjada dhererka ee tignoolajiyada laysarka, hubinta natiijooyinka ugu wanaagsan ee agabyada iyo codsiyada gaarka ah.
The525nm laser cagaaranwaa nooc gaar ah oo tignoolajiyada laysarka ah oo lagu garto sii daynta iftiinka cagaaran ee kala duwan oo dhererkiisu yahay 525 nanometer. Laysarada cagaaran ee mawjaddan dhererka ah waxay ka helayaan codsiyada xinjirowga indhaha, halkaasoo awooddooda sare iyo saxnaanta ay faa'iido u leedahay. Waxay sidoo kale faa'iido u leeyihiin habaynta walxaha, gaar ahaan meelaha u baahan habayn sax ah oo ugu yar ee saamaynta kulaylka.Horumarinta diodes-ka cagaaran ee c-plane GaN substrate ee ku wajahan mowjadaha dhaadheer ee 524-532 nm waxay calaamad u tahay horumarka la taaban karo ee tignoolajiyada laysarka. Horumarintani waxay muhiim u tahay codsiyada u baahan sifooyin dhererka dhererka gaarka ah

Laysarka Excimer, oo ku shaqeeya mawjada UV, waxay ku habboon yihiin ka baaraandegidda walxaha ballaaran ee bandgap sida dhalooyinka iyo kaarboon-fibre-xoojinta polymer (CFRP), oo bixiya saxnaanta sare iyo saameynta kulaylka ugu yar (Kobayashi et al., 2017).
Nd:YAG Lasers ee Codsiyada Warshadaha
Nd:YAG lasers, oo leh la qabsigooda marka la eego hagaajinta hirarka dhererka, ayaa loo adeegsadaa codsiyo kala duwan. Awoodooda ay ku shaqeeyaan labada 1064 nm iyo 532 nm waxay u oggolaanaysaa dabacsanaan xagga farsamaynta agabyada kala duwan. Tusaale ahaan, mawjada 1064 nm waxay ku habboon tahay xaradhka qoto dheer ee biraha, halka dhererka 532 nm uu bixinayo xaradh tayo sare leh oo dusha sare ah oo ku yaal balaastikada iyo biraha dahaarka leh.(Moon et al., 1999).
