Nd: YAG — Cov khoom siv laser zoo heev
Product Description
Nd: YAG tseem yog cov khoom siv hauv lub xeev laser nrog kev ua tau zoo tshaj plaws.Nd: YAG lasers yog optically pumped siv lub flashtube lossis laser diodes.
Cov no yog ib qho ntawm ntau hom laser, thiab yog siv rau ntau yam kev siv.Nd: YAG lasers feem ntau emit lub teeb nrog lub wavelength ntawm 1064nm, nyob rau hauv infrared.Nd:YAG lasers ua haujlwm nyob rau hauv ob qho tib si mem tes thiab nruam hom.Pulsed Nd: YAG lasers feem ntau ua haujlwm nyob rau hauv qhov hu ua Q-hloov hom: Ib qho kev hloov kho qhov muag tau muab tso rau hauv lub laser kab noj hniav tos kom muaj ntau tus neeg inversion hauv neodymium ions ua ntej nws qhib.
Tom qab ntawd lub teeb nthwv dej tuaj yeem khiav los ntawm kab noj hniav, depopulating lub siab laser nruab nrab ntawm qhov siab tshaj plaws ntawm cov pejxeem.Nyob rau hauv Q-hloov hom no, tso zis hwj chim ntawm 250 megawatts thiab mem tes ntev ntawm 10 mus rau 25 nanoseconds tau tiav lawm.[4]Lub siab siv pulses yuav ua tau zoo zaus ob npaug los tsim lub teeb laser ntawm 532 nm, lossis siab dua harmonics ntawm 355, 266 thiab 213 nm.
Lub Nd: YAG laser pas nrig ua los ntawm peb lub tuam txhab muaj cov yam ntxwv ntawm kev nce siab, tsis tshua muaj laser pib, zoo thermal conductivity thiab thermal shock.Nws yog tsim rau ntau hom kev ua haujlwm (nruam, mem tes, Q-hloov thiab hom xauv).
Nws yog feem ntau siv nyob rau hauv ze-far-infrared solid-state lasers, zaus ob npaug thiab zaus tripling daim ntaub ntawv, Nws yog dav siv hauv kev tshawb fawb, kev kho mob, kev lag luam thiab lwm yam kev lag luam.
