(Majumdar & Manna, 2013) Lawv tau tshwj xeeb rau microelectronics rau cov haujlwm zoo li kev kho mob pidterning, hauv cov txheej txheem kho mob zoo li cov txheej txheem kho mob rau hnub ci cell fabrication. Ntsuab lasers lub wavelength kuj ua rau lawv haum rau kev kos npe thiab cov hlau, qhov uas muaj kev puas tsuaj tsawg dua thiab cov khoom siv sib txawv. Qhov no yoog tau ntawm cov lasers ntsuab underscores qhov tseem ceeb ntawm wavelength xaiv hauv cov txiaj ntsig laser, ua kom pom tseeb zoo rau cov ntaub ntawv tshwj xeeb thiab kev siv.
Tus525nm ntsuab laserYog hom kev siv tshuab laser tshwj xeeb uas muaj cim los ntawm nws lub teeb pom kev zoo ntsuab ntawm lub nthwv dej ntawm 525 nanometers. Green Lasers ntawm lub wavelength pom cov ntawv thov hauv retinal photocoagulation, qhov twg lawv lub zog siab thiab precision muaj txiaj ntsig. Lawv kuj tseem muaj txiaj ntsig zoo hauv kev ua tiav, tshwj xeeb hauv cov teb uas yuav tsum tau ua kom haum thiab tsawg kawg thermal cuam tshuam ua.Kev txhim kho ntawm cov ntsuab laser donges ntawm c-dav hlau gan substrate ntawm lub sijhawm ntev ntev ntawm 524-532 nm cim ib qho kev nce qib hauv laser. Txoj kev txhim kho no yog qhov tseem ceeb rau cov ntawv thov uas xav tau cov wavelength
Nruam yoj thiab cov qauv teeb tsa laser
Nruam yoj (CW) thiab cov qauv nyiaj Quaper, ntsuab ntawm 1064 nm, thiab ultraviolet (thiab ulterer doping xaiv emitter solar hlwb. Wavelengths txawv tau cuam tshuam rau kev tsim khoom kom haum thiab ua haujlwm (Patel li al., 2011).
Lasers ua rau dav dav cov khoom sib txawv
Lasers ua kom tiav, kev khiav haujlwm ntawm UV yoj, tsim rau kev ua cov fiber ntau thiab cov pa roj carbon thiab), muab cov khoom siv thermal kub (kobayashi li al., 2017).
ND: YAG lasers rau kev siv cov ntawv thov
ND: YAG lasers, nrog lawv hloov kho ntawm nthwv cua tuning, yog siv nyob rau hauv ntau cov kev siv. Lawv lub peev xwm los ua haujlwm ntawm ob qho tib si 1064 nm thiab 532 nm pub rau kev yoog raws kev ua cov ntaub ntawv sib txawv. Piv txwv li, 1064 nm wavelength yog qhov zoo rau kev sib sib zog nqus cov hlau, thaum 532 nm waveling rau ntawm cov hniav thiab coated hlau. (1999).
