Laser thev naus laus zis muaj ntau yam tshwj xeeb uas cuam tshuam rau qhov zoo ntawm nws cov kev txiav.Cov degree uas lub teeb nkhaus nyob ib ncig ntawm qhov chaw yog hu ua diffraction, thiab feem ntau lasers muaj tsawg diffraction tus nqi kom pab tau ntau dua ntawm lub teeb siv nyob rau hauv ntev kev deb.Tsis tas li ntawd, cov yam ntxwv xws li monochromaticity txiav txim siablaser nqajlub wavelength zaus, thaum coherence ntsuas lub nruam lub xeev ntawm lub electromagnetic beam.Cov yam ntxwv no txawv raws li hom laser siv.Feem ntau hom kev lag luam laser txiav tshuab suav nrog:
Nd: YAG: Lub neodymium-doped yttrium aluminium garnet (Nd: YAG) laser siv cov khoom siv lead ua kom pom lub teeb rau nws lub hom phiaj.Nws tuaj yeem tua hluav taws tsis tu ncua lossis lub suab nrov infrared uas tuaj yeem txhim kho los ntawm cov khoom siv thib ob, xws li cov twj siv hluav taws xob lossis cov diodes.Nd: YAG qhov sib txawv ntawm cov nqaj sib txawv thiab qhov chaw ruaj khov ua rau nws ua tau zoo heev hauv kev ua haujlwm qis, xws li txiav cov ntawv hlau lossis txiav cov hlau nyias nyias.
CO2: Acarbon dioxide laser yog qhov muaj zog dua lwm txoj hauv kev rau Nd:YAG qauv thiab siv cov roj nruab nrab siv cov siv lead ua kom pom lub teeb.Nws cov zis-rau-pumping piv tso cai rau nws mus tua ib tug high-powered nruam beam muaj peev xwm ua tau zoo txiav cov ntaub ntawv tuab.Raws li nws lub npe qhia, lub laser cov pa tawm muaj ib feem ntawm carbon dioxide tov nrog me me ntawm nitrogen, helium, thiab hydrogen.Vim nws lub zog txiav, CO2 laser muaj peev xwm ntawm shaping bulky steel daim hlau mus txog 25 millimeters tuab, nrog rau txiav los yog engraving thinner cov ntaub ntawv ntawm qis zog.
