UV laser yog ib hom laser uas tsim ultraviolet beam. Tam sim no, excimer lasers thiab tag nrho cov khoom lub xeev lasers yog siv nyob rau hauv laser micromachining. Vim nws qhov luv wavelength, UV laser tuaj yeem nqus tau los ntawm cov ntaub ntawv feem ntau thiab muaj qhov zoo ntawm cov khoom siv laser. Nrog rau qhov tob ntawm kev tshawb fawb ntawm UV laser, daim ntawv thov teb ntawm UV laser txuas ntxiv nthuav dav. Tam sim no, nws tau siv nyob rau hauv ntau lub teb, xws li khoom noj khoom haus, tshuaj ntim khoom, electronics, semiconductors thiab lwm yam.
Khoom lub xeev UV lasers muab faib ua xenon teeb pumped UV lasers, krypton teeb pumped UV lasers thiab tshiab laser diode pumped tag nrho cov khoom lub xeev lasers. Feem ntau, kev sib xyaw tsim tau txais yuav, uas muaj cov yam ntxwv ntawm lub teeb me me, kev rov ua haujlwm siab, kev ua haujlwm ruaj khov, muaj zog cua sov dissipation peev, zoo nqaj zoo thiab lub zog ruaj khov.
UV laser muaj cov yam ntxwv tshwj xeeb. Nws yog hu ua "txias" ua. Lub laser nrog luv wavelength thiab mem tes dav thiab qis M2 (beam zoo) tuaj yeem tsim qhov chaw tsom ntau dua thiab tswj xyuas qhov tsawg kawg nkaus kub cuam tshuam cheeb tsam (HAZ). Hauv daim ntawv thov kos npe, nws tuaj yeem tuav cov khoom qub rau qhov loj tshaj plaws thiab txo qhov kev puas tsuaj thaum ua haujlwm. Xws li iav cim, ceramic carving, iav punching, mos Circuit Court board txiav thiab lwm yam kev siv, uas yog hlub los ntawm kev lag luam.
UV laser yog ib hom teeb pom kev ntawm qhov muag liab qab, nrog qhov chaw me me ({0}}.07mm), nqaim mem tes dav, ceev ceev thiab cov zis siab siab. Hauv zos irradiation ntawm lub workpiece nrog laser high-zog laser yuav gasify cov khoom nto los yog tsim photochemical cov tshuaj tiv thaiv ntawm cov xim hloov, tawm hauv lub cim mus tas li. Lub zog siab, siab pulse repetition rate (PRF), pulse shaping thiab pulse splitting tuaj yeem pab txhawb kev txhim kho kev tsim khoom ntawm micromachining.
Cov kws tshuaj ntsuam xyuas kev lag luam tau hais tias UV lasers tau siv dav. Nrog rau txoj kev loj hlob ntawm downstream 3C kev lag luam, kev lag luam thov rau UV lasers qhia tau hais tias ib tug fluctuating txoj kev loj hlob. Nyob rau hauv cov nqe lus ntawm cov khoom, UV laser cov khoom saum toj no 10W yog nyiam, thaum 30W UV laser khoom muaj ib tug zoo txoj kev vam meej. Nyob rau hauv cov nqe lus ntawm kev sib tw ua lag luam, lub lag luam UV laser yog ib qho tseem ceeb, thiab vim yog lub siab nkag thiab downstream hloov tus nqi ntawm kev lag luam, kev sib tw qauv ntawm UV laser lag luam yog qhov ruaj khov, thiab nws yog ib qho nyuaj rau cov neeg tuaj tshiab los nthuav. lub khw.
