Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, imishini yokusika i-fiber laser isetshenziswe kakhulu emakethe yezimboni. Imishini yokusika ye-fiber laser inokunemba okuphezulu kokusika nesivinini esisheshayo, esingathuthukisa ukusebenza kahle kuka-60% futhi songe izindleko eziningi. Ngakho-ke, bathandwa ngokujulile ngabantu. Uthando, manje vumela abakhiqizi bemishini yokusika i-fiber laser baqonde ukusetshenziswa komshini wokusika we-fiber laser emakethe yezimboni.
Cishe zonke izinto zensimbi zine-reflectivity ephezulu ekukhanyeni kwe-infrared ekamelweni lokushisa. Isibonelo, isilinganiso sokumuncwa kwe-10.6um carbon dioxide laser singu-0.5% kuya ku-10% kuphela, kepha lapho ugongolo olugxilile olunamandla amakhulu angaphezu kwe-10 ″ W / em2 lukhanya engxenyeni yensimbi, lungaba ngokulandelana ama-microsecond. Ubuso bangaphakathi buqala ukuncibilika. Izinga lokumunca izinsimbi eziningi ezincibilikisiwe lizokhuphuka kakhulu, ngokuvamile lifike kuma-60% -80%. Ngakho-ke, ama-lasers e-carbon dioxide asetshenziswe ngempumelelo emikhubeni eminingi yokusika izinsimbi.
Ubukhulu obukhulu bepuleti lensimbi yensimbi enganqunywa yizinhlelo zesimanje zokusika i-laser selwedlule u-20mm. Indlela yokusika i-fusion yokusiza oksijini isetshenziselwa ukusika amapuleti ensimbi ekhabhoni. Isikhala singalawulwa ngaphakathi kobubanzi obenelisayo, futhi isinqe samapuleti ensimbi amancane singaba sincane njengo-0.1 mm. mayelana. Ukusika i-Laser kuyindlela yokucubungula ephumelelayo yamapuleti ensimbi angenasici. Ingalawula indawo ethinteke ekushiseni ebangeni elincane, ukuze igcine ukumelana kwayo nokugqwala. Izinsimbi eziningi zesakhiwo se-alloy kanye nezinsimbi zensimbi zingasetshenziselwa ukuthola ikhwalithi enhle yokusika ngokusika kwe-laser.
Ama-aluminium ne-aluminium alloys awakwazi ukuncibilika futhi asikwe nge-oxygen. Indlela yokuncibilika nokusika kumele isetshenziswe. Ukusika i-Aluminium laser kudinga ukuqina kwamandla okuphezulu ukunqoba ukubukeka kwayo okuphezulu ku-10.6um wavelength laser. Ugongolo lwe-YAG laser olunobude obungu-1.06 um lungathuthukisa kakhulu ikhwalithi yokusika nejubane lokusika kwe-aluminium laser ngenxa yokumunca kwayo okuphezulu.
Ama-alloys e-titanium ne-titanium asetshenziswa kakhulu embonini yezindiza asebenzisa i-oxygen njengegesi elisizayo. Ukusabela kwamakhemikhali kuyesabeka futhi ijubane lokusika liyashesha, kepha kulula ukwakha ungqimba lwe-oxide onqenqemeni lokusika futhi lubangele nokushiswa komzimba. Kuphephe ukusebenzisa igesi engena njengegesi elisizayo, engaqinisekisa ikhwalithi yokusika.
