Laser sib xyaw rojyog hais txog kev ua haujlwm nruab nrab uas tsim los ntawm kev sib xyaw ntau cov pa roj hauv ib qho kev faib ua feem kom ua tiav cov txiaj ntsig laser tshwj xeeb thaum lub sijhawm laser tsim thiab cov txheej txheem thov. Ntau hom lasers xav tau kev siv cov laser sib xyaw nrog cov khoom sib txawv. Hauv qab no yog cov lus qhia ntxaws ntxaws rau koj:

Hom thiab kev siv

CO2 laser sib xyaw roj

Feem ntau yog tsim los ntawm carbon dioxide (CO2), nitrogen (N2) thiab helium (HE). Hauv kev lag luam kev lag luam, xws li txiav, vuam thiab kho qhov chaw, carbon dioxide lasers tau siv dav. Ntawm lawv, cov pa roj carbon dioxide yog cov khoom tseem ceeb rau kev tsim cov lasers, nitrogen tuaj yeem ua kom lub zog hloov pauv ntawm cov pa roj carbon dioxide molecules thiab ua kom lub zog tso zis laser, thiab helium pab kom cov cua sov thiab tswj kev ruaj ntseg ntawm cov pa tawm, yog li txhim kho cov kab teeb pom kev zoo.

Excimer laser mix gas

Sib xyaw los ntawm cov pa roj tsawg (xws li argon (AR),Krypton (KR), xenon (XE)) thiab halogen ntsiab (xws li fluorine (F), chlorine (CL)), xws liARF, KRF, XeCl,thiab lwm yam. Hom laser no feem ntau siv hauv tshuab photolithography. Nyob rau hauv semiconductor nti manufacturing, nws muaj peev xwm ua tau high-resolution graphic hloov lwm lub tsev; Nws kuj tseem siv tau rau hauv kev phais mob ophthalmic, xws li excimer laser hauv situ keratomileusis (LASIK), uas tuaj yeem txiav cov ntaub so ntswg kom raug thiab pom tseeb.

Helium-neonlaser rojsib tov

Nws yog ib tug sib tov ntawmheliumthiabneonnyob rau hauv ib qho piv txwv, feem ntau ntawm 5: 1 thiab 10: 1. Helium-neon laser yog ib qho ntawm cov roj lasers thaum ntxov, nrog cov zis tawm ntawm 632.8 nanometers, uas yog lub teeb liab pom. Nws yog feem ntau siv hauv kev ua yeeb yam kho qhov muag, holography, laser taw tes thiab lwm yam kev lag luam, xws li kev sib tw thiab qhov chaw hauv kev tsim kho, thiab tseem nyob rau hauv barcode scanners hauv khw loj.

Kev ceev faj rau kev siv

High purity yuav tsum: impurities nyob rau hauv lub laser roj sib tov yuav cuam tshuam lub laser tso zis zog, stability thiab beam zoo. Piv txwv li, ya raws yuav corrode lub sab hauv ntawm lub laser, thiab oxygen yuav oxidize lub optical Cheebtsam thiab txo lawv cov kev ua tau zoo. Yog li ntawd, cov roj purity feem ntau xav tau ntau tshaj 99.99%, thiab cov ntawv thov tshwj xeeb txawm xav tau ntau dua 99.999%.

Qhov tseeb piv: Qhov piv ntawm txhua qhov roj muaj feem cuam tshuam rau kev ua haujlwm ntawm laser, thiab qhov sib piv yuav tsum nruj me ntsis raws li cov qauv tsim laser. Piv txwv li, nyob rau hauv ib tug carbon dioxide laser, kev hloov nyob rau hauv piv ntawm nitrogen rau carbon dioxide yuav cuam tshuam lub laser tso zis zog thiab efficiency.

Kev ruaj ntseg cia thiab siv: Qee yamlaser mix gasesyog toxic, corrosive, los yog flammable thiab tawg. Piv txwv li, cov roj fluorine nyob rau hauv excimer laser yog heev toxic thiab corrosive. Kev ntsuas kev nyab xeeb nruj yuav tsum tau ua thaum lub sijhawm khaws cia thiab siv, xws li siv cov thawv ntim khoom kaw kom zoo, nruab nrog cov khoom siv cua thiab cov khoom siv hluav taws xob pom, thiab lwm yam.
