Laser sib xyaw rojhais txog ib qho chaw ua haujlwm uas tsim los ntawm kev sib xyaw ntau cov pa roj hauv ib qho kev faib ua feem kom ua tiav cov yam ntxwv tshwj xeeb ntawm cov zis laser thaum lub sijhawm tsim laser thiab cov txheej txheem thov. Ntau hom lasers xav tau kev siv cov pa roj sib xyaw laser nrog cov khoom sib txawv. Cov hauv qab no yog cov lus qhia ntxaws rau koj:

Cov hom thiab daim ntawv thov uas siv ntau

CO2 laser sib xyaw roj

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

Excimer laser sib xyaw roj

Sib xyaw los ntawm cov pa roj tsawg (xws li argon (AR),krypton (KR), xenon (XE)) thiab cov ntsiab lus halogen (xws li fluorine (F), chlorine (CL)), xws liARF, KRF, XeCl,thiab lwm yam. Hom laser no feem ntau siv rau hauv kev siv tshuab photolithography. Hauv kev tsim cov chip semiconductor, nws tuaj yeem ua tiav kev hloov pauv duab siab; nws kuj tseem siv rau hauv kev phais qhov muag, xws li excimer laser hauv situ keratomileusis (LASIK), uas tuaj yeem txiav cov ntaub so ntswg corneal thiab kho qhov muag.

Helium-neonroj lasersib xyaw

Nws yog ib qho sib xyaw 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 tshaj plaws, nrog rau qhov tso zis wavelength ntawm 632.8 nanometers, uas yog lub teeb pom kev liab. Nws feem ntau siv rau hauv kev ua qauv qhia pom, holography, laser taw tes thiab lwm yam teb, xws li kev sib dhos thiab kev tso rau hauv kev tsim kho, thiab tseem nyob rau hauv cov tshuab ntsuas barcode hauv cov khw muag khoom loj.

Cov kev ceev faj rau kev siv

Cov kev xav tau ntawm kev huv siab: Cov khoom tsis huv hauv cov roj laser sib xyaw yuav cuam tshuam rau lub zog tso zis laser, kev ruaj khov thiab qhov zoo ntawm lub teeb. Piv txwv li, cov dej noo yuav ua rau cov khoom sab hauv ntawm lub laser xeb, thiab cov pa oxygen yuav ua rau cov khoom siv kho qhov muag oxidize thiab txo lawv cov kev ua tau zoo. Yog li ntawd, cov roj purity feem ntau yuav tsum ncav cuag ntau dua 99.99%, thiab cov ntawv thov tshwj xeeb txawm tias xav tau ntau dua 99.999%.

Qhov sib piv tseeb: Qhov sib piv ntawm txhua qhov roj muaj feem cuam tshuam loj heev rau kev ua haujlwm ntawm laser, thiab qhov sib piv tseeb yuav tsum ua raws li cov qauv tsim laser. Piv txwv li, hauv lub laser carbon dioxide, kev hloov pauv ntawm qhov sib piv ntawm nitrogen rau carbon dioxide yuav cuam tshuam rau lub zog tso zis laser thiab kev ua haujlwm zoo.

Kev khaws cia thiab siv kom muaj kev nyab xeeb: Qee qhovlaser sib xyaw cov pa rojyog lom, corrosive, lossis flammable thiab tawg. Piv txwv li, cov roj fluorine hauv lub laser excimer yog lom heev thiab corrosive. Yuav tsum tau ua raws li kev nyab xeeb thaum lub sijhawm khaws cia thiab siv, xws li siv cov thawv cia khoom kaw zoo, nruab nrog cov khoom siv cua thiab cov khoom siv nrhiav roj, thiab lwm yam.
