Laser txiav yog kev siv lub zog hluav taws xob Laser Beam rau Irradiate cov khoom txiav, ua rau nws tau nrawm nrawm nrawm thiab evaporate rau daim qhov. Raws li cov nqaj txav cov khoom, lub qhov txuas txuas ntxiv nqaim (xws li nyob ib ncig ntawm 0.1mm) slits, ua tiav cov khoom txiav. Laser txiav yog ib qho ntawm cov txheej txheem thermal txiav.
Kev hloov kho thiab kho dua tshiab ntawm cov cuab yeej laser tau dhau los ua nrawm dua thiab nrawm dua, thiab kev lag luam laser hauv tsev thiab thoob ntiaj teb tau nce mus rau lub sijhawm ntawm kev loj hlob sai, nrog nanoseconds, picoseconds, thiab femtoseconds maj mam dhau los ua cov ntsiab lus kub hauv kev ua lag luam. Dav siv nyob rau hauv ntau yam kev tsim thiab kev lag luam xws li cov ntawv hlau ua, aviation, aerospace, electronics, khoom siv hluav taws xob, subway accessories, tsheb, grain machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical khoom, elevators, khoom siv hauv tsev, khoom siv tes ua khoom plig, cuab yeej ua, kho kom zoo nkauj, tshaj tawm, hlau sab nraud ua, khoom siv hauv chav ua noj, thiab lwm yam.
Yog li, dab tsi yog qhov txawv ntawm nanoseconds, picoseconds, thiab femtoseconds hauv laser txiav?
1. Lub tswv yim ntawm qhov sib txawv ntawm nanoseconds, picoseconds, thiab femtoseconds hauv laser txiav:
Cov nanoseconds, picoseconds, thiab femtoseconds nyob rau hauv laser ua khoom xa mus rau lub sij hawm tswj units nyob rau hauv cov txheej txheem laser. Feem ntau, kev ua laser muaj ib lub zog ntawm lub zog ua haujlwm ntawm cov khoom siv hauv lub sijhawm luv luv, tsim cov ntawv thov xws li drilling, txiav, kos, thiab vuam los ntawm kev ua haujlwm ntau zaus.
Tib lub sijhawm, nws yuav tsum raug sau tseg tias 1 thib ob =109 nanoseconds =1012 picoseconds=1015 femtoseconds. Yog li ntawd, nanosecond, picosecond, thiab femtosecond laser ua cov khoom siv feem ntau pom nyob rau hauv kev ua lag luam yog lub npe raws li lub sij hawm, nrog rau ntau yam xws li ib tug mem tes zog, mem tes dav, mem tes zaus, thiab mem tes pulse zog. Raws li kev xav tau ntawm cov khoom sib txawv, cov khoom siv nanosecond, picosecond, thiab femtosecond laser processing yuav tsum raug xaiv. Lub sij hawm luv dua, lub sij hawm luv luv uas lub laser ua rau ntawm cov khoom nto, qhov cuam tshuam me me ntawm cov khoom nto, thiab qhov ua tau zoo dua.
2. Qhov txawv ntawm nanoseconds, picoseconds, thiab femtoseconds nyob rau hauv laser txiav: cov ntaub ntawv ua:
Raws li kev ua haujlwm sib txawv, cov sijhawm sib txawv tau xaiv, uas yog vim li cas thiaj li muaj cov cai naming rau nanosecond, picosecond, thiab femtosecond laser khoom. Piv txwv li, nanosecond ultraviolet laser txiav tshuab feem ntau yog siv rau nyias zaj duab xis cov ntaub ntawv ua, picosecond ultraviolet laser txiav tshuab feem ntau siv rau brittle cov ntaub ntawv ua, thiab femtosecond ultraviolet hlau laser txiav tshuab yog siv rau conductive nyias zaj duab xis oxide thiab lwm yam khoom siv (ultraviolet. yog lub npe raws li txoj cai wavelength thiab yog 355nm laser).
3. Qhov txawv ntawm nanoseconds, picoseconds, thiab femtoseconds nyob rau hauv laser txiav thiab nws cov kev siv:
Laser drilling yog ib qho ntawm cov kev siv ntau tshaj ntawm picosecond laser, uas tuaj yeem ua tiav qhov ua tiav los ntawm kev cuam tshuam drilling thiab xyuas kom lub qhov sib xws. Ntxiv nrog rau lub rooj tsav xwm hauv Circuit Court, picosecond lasers kuj tuaj yeem laum qhov zoo hauv cov ntaub ntawv xws li yas zaj duab xis, semiconductors, hlau zaj duab xis, thiab sapphires.
Kab ablation (tshem tawm cov coatings) yog ib qho ntawm cov kev siv micro ua ntawm picosecond lasers, uas yog tshem tawm cov coatings yam tsis muaj kev puas tsuaj los yog me ntsis ua rau cov khoom siv substrate. Ablation tuaj yeem yog ob peb microns dav kab lossis thaj tsam loj ntawm kev tshem tawm hauv ob peb square centimeters. Vim qhov tseeb tias lub thickness ntawm txheej yog feem ntau me dua qhov dav ntawm ablation, cua sov tsis tuaj yeem kis tau ntawm sab. Yog li ntawd, lasers nrog nanosecond mem tes dav siv tau.
Precision laser txiav yog ib qho kev siv ntau ntawm femtosecond laser, uas tuaj yeem siv los txiav ntau yam substrates.
Tam sim no, lub lag luam tseem ceeb ntawm laser ua lag luam nyob rau hauv kev ua lag luam yog tseem dominated los ntawm nanosecond lasers, vim tus nqi siab ntawm picosecond ultra ceev laser txiav tshuab. Cov qauv yav tom ntej yog twv yuav raug hu mus rau txoj kev loj hlob ntawm picosecond thiab femtosecond teb, thiab yav tom ntej yog foreseeable.
Hais txog HGTECH: HGTECH yog tus pioneer thiab tus thawj coj ntawm daim ntawv thov kev lag luam laser hauv Suav teb, thiab cov neeg muab kev tso cai ntawm kev daws teeb meem laser thoob ntiaj teb. Peb tau ua tiav cov txheej txheem laser ntse tshuab, ntsuas thiab automation ntau lawm kab, thiab ntse Hoobkas tsim los muab tag nrho cov kev daws teeb meem rau kev tsim khoom ntse.
