Raws li ib qho ntawm cov kev lag luam qib tseem ceeb tam sim no, cov khoom siv hluav taws xob UV lasers tau siv dav hauv ntau qhov kev lag luam raws li lawv cov kev ua tau zoo ntau yam vim lawv qhov dav dav dav, ntau lub wavelengths, cov khoom siv loj, lub zog siab thiab cov khoom siv zoo.Nta, thiab ultraviolet laser wavelength yog 355nm, uas yog lub teeb txias qhov chaw, uas tuaj yeem nqus tau zoo dua los ntawm cov khoom siv, thiab kev puas tsuaj rau cov khoom siv kuj tsawg.Nws tuaj yeem ua tau zoo micro-machining thiab cov khoom siv tshwj xeeb uas tsis tuaj yeem ua tiav los ntawm cov pa CO2 lasers thiab fiber ntau lasers.
Ultraviolet lasers raug cais raws li qhov ntau ntawm cov zis band.Lawv feem ntau piv nrog infrared lasers thiab pom lasers.Cov lasers infrared thiab pom lub teeb feem ntau ua tiav los ntawm cov cua sov hauv zos kom yaj lossis vaporize cov khoom, tab sis cov cua sov no yuav ua rau cov khoom nyob ib puag ncig cuam tshuam.Kev puas tsuaj yog li txwv ntug lub zog thiab muaj peev xwm tsim me me, zoo nta.Ultraviolet lasers ncaj qha rhuav tshem cov tshuaj bonds uas khi cov atomic Cheebtsam ntawm ib yam khoom.Cov txheej txheem no, hu ua "txias" txheej txheem, tsis tsim cov cua sov ntawm lub periphery tab sis ncaj qha cais cov khoom rau hauv atoms.
