Kev siv lub laser raws li ib lub cuab yeej rau kev kos cov hlau yog zoo heev. Thaum kos npe cov ntaub ntawv hlau, lub teeb ci ntsa iab nrog lub wavelength ntawm 1064 nm feem ntau yog siv. Txawm li cas los xij, rau cov hlau uas muaj kev siab dua, xws li txhuas, tooj liab thiab kub, lawv tsuas nqus ib qho me me ntawm qhov teeb meem qhov teeb meem.
Cov lasers ntawm MRJ-laser muaj qhov zoo ntawm qhov zoo beam zoo thiab siab ncov zog. Hauv qhov no, xaiv ib txoj kab-luv taw-ntev (xws li lub teeb ntsuab) kuj yuav ua rau muaj kev kos npe zoo vim tias cov hlau ua kom luv luv-wavelength teeb yooj yim dua.
MRJ-Laser muaj cov neeg lag luam ntau hom laser marking cov cav tov nrog txawv zog, txawv plhaub wides thiab ntau txoj kev xaiv wavelength. Siab nruab nrab lub hwj chim feem ntau ua tau zoo tshaj plaws.
Txawm li cas los xij, hauv lub laser marking txheej txheem, tsis tsuas yog lub hwj chim tseem ceeb, tab sis kuj nqaj zoo yog qhov tseem ceeb sib luag. Qhov zoo tshaj plaws nqaj qaum pub rau nws kom pom cov teeb meem ntawm laser ntawm lub taw tes me me kom lub workpiece ntws tuaj yeem ua tau siab muaj zog. Qhov chaw me me thermal effect. Li no ua tau zoo ntawm lub laser npav ntawm lub tshuab hlau laser marking tshuab.
Txij thaum lub sij hawm luv-luaj laser tuaj yeem ua kom zoo, qhov kos npe yog ntau dua nyob rau hauv rooj plaub uas qhov chaw hauv cheeb tsam me me. Cov teeb meem laser pulsed ua rau cov workpiece nyob hauv ib qho kev nyuaj ntawm ib zaug-piv pulses uas yog nyob ib sab los yog ntau dua. Pulses emit ib qho tseeb ntawm lub zog uas tso cai rau lub zog thiab kub kom nkag mus rau cov khoom.
Tsuas yog ib qho me me ntawm thaj chaw yog cuam tshuam los ntawm thermal thiab mechanical effects. Feem ntau, muaj ntau yam peb txoj kev siv dav hlau siv rau hauv cov tshuab muaj hlau: kos xim, ablation, thiab ntuav.
