Waa maxay laysarka?
Marka la soo koobo, laysarka waa iftiinka ka soo baxa kicinta walxaha. Waxaanna qaban karnaa shaqo badan oo leh laambad laysar ah.
Wikipedia, A laysarwaa qalab iftiimiya iftiinka iyada oo loo marayo habka kor u qaadista indhaha oo ku salaysan sii deynta kicinta ee shucaaca elektromagnetic-ka. Ereyga "laser" waa erey la soo gaabiyay oo loogu talagalay "kor u qaadista iftiinka iyada oo loo marayo sii deynta kicinta ee shucaaca". Laysarka ugu horreeya waxaa dhisay 1960-kii Theodore H. Maiman oo ka tirsan Hughes Research Laboratories, oo ku salaysan shaqada aragtiyeed ee Charles Hard Townes iyo Arthur Leonard Schawlow.
Laser-ku wuu ka duwan yahay ilaha kale ee iftiinka isagoo soo saaraya iftiin isku xiran. Isku-xidhnaanta booska wuxuu u oggolaanayaa laser-ka in diiradda la saaro meel cidhiidhi ah, taasoo suurtogalinaysa codsiyada sida jarista laysarka iyo lithography-ga. Isku-xidhnaanta booska ayaa sidoo kale u oggolaanaysa iftiinka laysarka inuu cidhiidhi ahaado masaafooyin waaweyn (isku-xidhnaan), taasoo awood u siinaysa codsiyada sida tilmaamaha laysarka iyo lidar-ka. Laser-yadu waxay sidoo kale yeelan karaan isku-xidhnaan meel-dhexaad ah oo sare, taasoo u oggolaanaysa inay soo saaraan iftiin leh muuqaal aad u cidhiidhi ah. Taas beddelkeeda, isku-xidhnaanta waqtiga-dhabta ah waxaa loo isticmaali karaa in lagu soo saaro garaacyo iftiin oo aad u gaaban oo leh muuqaal ballaaran laakiin soconaya sida femtosecond.
Laser-yada waxaa loo isticmaalaa darawallada saxannada indhaha, daabacayaasha laysarka, iskaan-gareeyayaasha barcode-ka, qalabka taxanaha DNA-da, fiber-optic, wax-soo-saarka jajabka semiconductor (photolithography), iyo isgaarsiinta indhaha ee bannaanka ah, qalliinka laysarka, iyo daawaynta maqaarka, qalabka jarista iyo alxanka, aaladaha militariga iyo fulinta sharciga si loo calaamadeeyo bartilmaameedyada iyo cabbiraadda baaxadda iyo xawaaraha, iyo bandhigyada iftiinka laysarka ee madadaalada.
Ka dib horumar taariikhi ah oo dheer oo tignoolajiyada laysarka ah, laysarka waxaa loo isticmaali karaa codsiyada warshadaha ee kala duwan, waana mid ka mid ah isticmaalka ugu badan ee warshadaha jarista, haddii aan biraha lahayn warshadaha birta ama kuwa aan birta ahayn, mashiinka jarista laysarka ayaa cusboonaysiiya habka jarista dhaqameed, hagaajinta waxtarka wax soo saarka badan ee warshadaha wax soo saarka, sida dharka, dharka, roogagga, alwaaxa, acrylic, xayaysiinta, shaqada birta, baabuurta, qalabka jimicsiga iyo warshadaha alaabta guriga.
Laser wuxuu noqday mid ka mid ah qalabka ugu wanaagsan ee jarista sababtoo ah sifooyinka goynta saxda ah iyo xawaaraha sare.
