Ubuchwepheshe be-laser bunezici ezimbalwa ezihlukile ezithinta ikhwalithi yokusikeka kwayo.Izinga lapho amajika okukhanya azungeze izindawo aziwa ngokuthi i-diffraction, futhi ama-laser amaningi anamazinga aphansi oku-diffraction ukuze anike amandla amazinga aphezulu okuqina kokukhanya kumabanga amade.Ngaphezu kwalokho, izici ezifana ne-monochromaticity zinqumaugongolo laserimvamisa ye-wavelength, kuyilapho ukuhlangana kukala isimo esiqhubekayo se-electromagnetic beam.Lezi zici ziyahlukahluka kuye ngohlobo lwe-laser esetshenzisiwe.Izinhlobo ezivame kakhulu zezimboni laser cutting izinhlelo zihlanganisa:
Nd: YAG: Ilaser ye-neodymium-doped yttrium aluminium garnet (Nd:YAG) isebenzisa into eyikristalu eqinile ukuze igxilise ukukhanya kumgomo wayo.Ingashisa i-infrared eqhubekayo noma enesigqi engathuthukiswa okokusebenza kwesibili, njengamalambu okumpompa abonakalayo noma ama-diode.Uhlaka lwe-Nd:YAG oluhluka ngokuqhathaniswa kanye nokuzinza okuphezulu kwesikhundla kuyenza isebenze kahle kakhulu emisebenzini enamandla aphansi, njengokusika insimbi yeshidi noma ukusika insimbi yegeji elincane.
CO2: I-Acarbon dioxide laser ingenye enamandla kakhulu kumodeli ye-Nd:YAG futhi isebenzisa indawo yegesi esikhundleni sekristalu ukugxilisa ukukhanya.I-output-to-pumping ratio yayo ivumela ukuthi iqhumise i-high-powered okuqhubekayo igobolondo elikwazi ukusika ngokuphumelelayo izinto eziwugqinsi.Njengoba igama layo libonisa, ukukhishwa kwegesi ye-laser kuhlanganisa ingxenye enkulu ye-carbon dioxide exutshwe namanani amancane e-nitrogen, i-helium, ne-hydrogen.Ngenxa yamandla ayo okusika, i-CO2 laser iyakwazi ukubumba amapuleti ensimbi amakhulu aze afike kumamilimitha angu-25 ubukhulu, kanye nokusika noma ukuqopha izinto ezizacile ngamandla aphansi.
