Tam sim no, muaj ob lub ntsiab ntawm kev lag luam lasers rau kev ua cov laser: cov khoom hluav taws xob zoo-lub xeev lasers thiab roj lasers. Ntawm lawv, solid-state laser yog sawv cev los ntawm Nd: YAG laser, thiab cov pa roj laser tau sawv cev los ntawm CO2 laser. Nrog rau kev tsim cov tshuab laser, cov tshuab hluav taws xob fiber ntau thiab cov tshuab hluav taws xob ntau lub tshuab hluav taws xob tau pib siv nyob rau hauv qee yam kev siv.
1) Nd: YAG laser
Lub laser ua haujlwm cov khoom siv ntawm Nd: YAG laser yog lub zog Nd: YAG pas nrig nrog lub teeb laser ntev ntawm 1.06 μm. Vim tias qhov teeb meem laser hloov qis tsawg dua ntawm qhov laser no thiab qhov kev txwv ntawm YAG pas nrig ntim thiab cov thermal conductivity, qhov nruab nrab laser tso zis hluav taws xob tsis loj. Txawm li cas los xij, txij li lub Nd: YAG laser tuaj yeem ceev cov mem tes qhov dav ntawm lub laser tso tawm los ntawm Q hloov, nws tuaj yeem tau txais lub ncov muaj zog heev (108W) thaum ua haujlwm nyob rau hauv hom mem tes, uas tsim nyog rau laser ua cov ntawv thov kom muaj lub siab siab. fais fab tuag; lwm qhov txiaj ntsig tseem ceeb Nws tuaj yeem kis tau los ntawm cov kab ke kho qhov muag, zam kev tsim qauv thiab tsim cov khoom lag luam sib kis tau yooj yim, thiab muaj txiaj ntsig zoo hauv kev ua 3D. Tsis tas li ntawd, lub laser wavelength tuaj yeem hloov pauv mus rau 355 nm (ultraviolet) los ntawm triple zaus siv thev naus laus zis, uas yog siv hauv laser stereo forming technology.
2) CO2 laser
Cov cuab yeej ua haujlwm laser ntawm lub CO2 laser yog lub CO2 sib xyaw roj, thiab nws lub ntsiab thov laser wavelength yog 10.6 μm. Txij li lub laser muaj qhov siab hloov dua siab tshiab efficiency, thiab lub tshav kub tsim los ntawm lub laser tuaj yeem ceev nrawm rau thaj tsam laser nce ntxiv los ntawm convection lossis diffusion, qhov nruab nrab tso tawm lub zog ntawm lub laser tuaj yeem ua tiav theem siab heev (tshaj 10,000 watts) Cov. Lub zog ua hluav taws xob siab laser ua kom ua tau.
Lub zog hluav taws xob ntau CO2 lasers rau kev ua cov laser hauv tsev thiab txawv teb chaws feem ntau yog cov ntoo khaub lig-ntws thiab axial-flow lasers. 1 Cross-flow laser: Cov nqaj zoo ntawm cov kab hla hla laser tsis zoo heev, nws yog qhov tso tawm ntau hom, feem ntau yog siv rau kev kho tshav kub thiab vuam. Tam sim no, Tuam Tshoj muaj peev xwm tsim ntau yam ntawm cov hluav taws xob siab hla hluav taws xob CO2 laser series, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev kho cua sov hauv tsev laser thiab vuam. 2 axial flow laser: Cov axial nqaj laser muaj qhov nqaj zoo tau zoo thiab yog qhov pib hom lossis quasi-puag tsim tawm cov zis. Nws yog tsuas yog siv rau laser txiav thiab vuam. Lub tshuab laser txiav cov khoom lag luam nyob hauv Suav teb feem ntau nyob hauv txawv teb chaws axial lasers tam sim no. Txawm hais tias qhov chaw tsim hluav taws xob laser tau ua ntau yam haujlwm ntawm txawv teb chaws axial lasers tam sim no, vim tias cov khoom tseem ceeb tseem yuav tsum tau ntshuam, tus nqi ntawm cov khoom lag luam nyuaj nyuaj poob thiab qhov kev nkag siab yog tsawg.
