Waa maxay laysarka
Marka la soo koobo, laserku waa iftiinka ay soo saarto kicinta walxaha.Oo waxaan ku qaban karnaa shaqo badan oo leh laydhka laysarka.
Wikipedia, A leysarkawaa qalab ku sii daaya iftiin iyada oo loo marayo habka kor u qaadida indhaha ee ku salaysan qiiqa la kiciyey ee shucaaca korantada.Erayga "laser" waa erey la soo gaabiyey "iftiin ku kordhinta shucaaca la kiciyey".Layskii ugu horreeyay waxaa la dhisay 1960-kii waxaa dhisay Theodore H. Maiman oo ka tirsan Hughes Research Laboratories, oo ku salaysan shaqada aragtida Charles Hard Townes iyo Arthur Leonard Schawlow.
Laysarka wuxuu kaga duwan yahay ilaha kale ee iftiinka inuu soo saaro iftiin isku xiran.Isku xirnaanta boosaska ayaa u ogolaaneysa laysarka in diirada la saaro meel cidhiidhi ah, taas oo awood u siinaysa codsiyada sida jarista laysarka iyo lithography.Isku-xidhnaanta meel bannaan waxay sidoo kale u oggolaanaysaa laydhka laysarka inuu ku sii yaraado masaafo aad u weyn (isku-dhafka), taas oo awood u siinaysa codsiyada sida tilmaamayaasha laysarka iyo lidar.Laser-ku waxay sidoo kale yeelan karaan isku xirnaan heer sare ah oo ku meel gaar ah, taas oo u oggolaanaysa inay iftiimiyaan iftiin leh spectrum aad u cidhiidhi ah.Taas beddelkeeda, isku-xidhnaanta ku-meel-gaadhka ah ayaa loo isticmaali karaa in lagu soo saaro garaaca iftiinka ultra-gaaban oo leh spectrum ballaaran laakiin muddada u gaaban sida femtosecond.
Lasers-ka waxaa loo adeegsadaa darawallada indhaha, daabacayaasha laysarka, iskaanka barcode, aaladaha isku xigxiga DNA, fiber-optic, wax-soo-saarka chip semiconducting (photolithography), iyo isgaarsiinta indhaha ee bilaashka ah, qaliinka laysarka, iyo daaweynta maqaarka, goynta iyo alxanka agabka, militariga iyo qalabka fulinta sharciga calaamadaynta bartilmaameedyada iyo cabbirka baaxadda iyo xawaaraha, iyo bandhigyada laydhka laysarka ee madadaalada.
Ka dib markii horumarinta taariikhiga ah dheer technology laser, laser waxaa loo isticmaali karaa in codsiga warshadaha badan oo kala duwan, iyo mid ka mid ah isticmaalka kacaanka ugu haddii goynta warshadaha, ma biraha biraha ama warshadaha non-birta, cusboonaysiinta mashiinka goynta laser habka goynta dhaqanka, horumarinta wax soo saarka badan oo waxtarka warshadaha wax soo saarka, sida dharka, dunta, rooga, alwaax, acrylic, xayeysiis, biraha, baabuurta, qalabka jirdhiska iyo alaabta guryaha.
Laser-ku wuxuu noqday mid ka mid ah aaladaha goynta ugu wanaagsan ee sababa astaamaha goynta saxda ah ee xawaaraha sare leh.
