Nd: YAG - Qalab Laser Adag oo heer sare ah
Sharaxaada Alaabta
Nd: YAG wali waa walaxda laysarka ee adag ee leh waxqabadka ugu fiican. Nd: laser-yada YAG si indho la'aan ah ayaa loo shubaa iyadoo la isticmaalayo flashtube ama diodes leysarka.
Kuwani waa mid ka mid ah noocyada ugu caansan ee laysarka, waxaana loo isticmaalaa codsiyo badan oo kala duwan. Nd: laser-yada YAG waxay caadi ahaan sii daayaan iftiin leh hirar dhererkiisu yahay 1064nm, gudaha infrared-ka. Nd:YAG lasers waxay ku shaqeeyaan qaab garaacis iyo mid joogto ah labadaba. Pulsed Nd: YAG lasers waxaa sida caadiga ah lagu shaqeeyaa habka loo yaqaan Q-switching mode: Dareemida indhaha ayaa la geliyey godka laysarka oo sugaya inta ugu badan ee dadweynaha ee ions neodymium ka hor inta aanu furmin.
Dabadeed mowjadda iftiinka waxay dhex mari kartaa daloolka, oo baabi'inaysa dhexdhexaadiyaha laysarka ee xiisaha leh marka ugu badan ee dadka rogaan. Habkan Q-bedeshay, awoodaha wax soo saarka ee 250 megawatts iyo muddada garaaca wadnaha ee 10 ilaa 25 nanoseconds ayaa la gaadhay.[4] Xawaaraha sare ee garaaca waxaa laga yaabaa in si hufan loo labanlaabo si loo dhaliyo iftiinka laysarka ee 532 nm, ama harmonics ka sareeya 355, 266 iyo 213 nm.
Nd: Usha laser YAG ee ay soo saartay shirkadeena waxay leedahay sifooyin faa'iido sare leh, marinka laser hooseeya, kuleylka kuleylka wanaagsan iyo shoogga kulaylka. Waxay ku habboon tahay noocyada kala duwan ee hababka shaqada (sii socota, garaaca wadnaha, Q-switch iyo qufulka qaabka).
Waxaa caadi ahaan loo isticmaalaa in u dhow-fog-infrared adag-state lasers, inta jeer ee labanlaabmay iyo inta jeer ee codsiyada saddex laabashada, Waxaa si weyn loo isticmaalaa in cilmi-baarista sayniska, daaweynta caafimaadka, warshadaha iyo beeraha kale.
