Avelaphi ama-laser?
Ithiyori yelaser(Laser Amplification by Stimulated Emission of Radiation) yavela ku-Albert Einstein ngo-1917, owakhomba uchungechunge lwethiyori yezobuchwepheshe mayelana nokusebenzisana phakathi kokukhanya nento (Zur Quantentheorie der Strahlung).
Ngokombono, kunezinombolo ezahlukene zezinhlayiya ezisatshalaliswa emazingeni ahlukene wamandla. Futhi izinhlayiya ezingeni eliphezulu lamandla zizogxumela ezingeni eliphansi lamandla lapho zijatshuliswa i-photon ethile. Ezingeni eliphansi lamandla, ukukhanya kwemvelo efanayo nokukhanya okujabulisayo kuzokhipha imisebe. Futhi ukukhanya kweviki kungajabulisa ukukhanya okunamandla esimweni esithile.
Ngemva kwalokho, uRudolf W.Ladenburg, uValentin A. Fabrikant, uWillis E. imvu, u-Alfred Rastler Joseph Weber kanye nabacwaningi abaningi benza iminikelo ekuhloleni ama-lasers.
Namuhla, ngithanda ukunaka kakhulu ukusetshenziswa kwama-laser, njengokusika nokuqopha nge-laser, i-laser welding kanye nokumaka nge-laser. Ukusetshenziswa kwe-laser cutting kwaqala ngo-1963, kwakudume ngezinzuzo ezine, ukukhanya okuphezulu, isiqondiso esiphezulu, i-monochromaticity ephezulu kanye nokuhambisana okuphezulu. Akukho ukuguqulwa nokugqokwa kwamathuluzi ngesikhathi sokusebenza njengoba i-laser ayixhumani nezinto zokucubungula. Ngaphezu kwalokho, iwukucubungula okuguquguqukayo okusika futhi kubhoboze izinto zensimbi ngokushesha okukhulu kohlaka namandla anamandla.
Ngaphezu kwalokho, uma uke wezwa ukushisela kwe-laser, ukushintshwa okusha kwe-welding evamile, uzokwazi ukuthi kuyindlela ephumelelayo. Hhayi nje ngenxa yokuguquguquka okukhulu, kodwa futhi ngenxa yezinzuzo ezibanzi.
Ngokusekelwe ophahleni lwe-laser optical, izisebenzi zingashisela izinto zensimbi ngaphandle kwesigcwalisi kanye ne-welding flux. Uma kuqhathaniswa ne-argon arc welding yendabuko, indlela evame kakhulu yokushisela okwamanje, i-fiber laser welding ingadlula ezintweni ezibonakalayo, ezingavimbela kakhulu ukulimala kwakhe ngokucubungula okukude. Futhi ingasetshenziswa endaweni eyingozi kakhulu, njengokushisa okuphezulu, ukubanda okuphezulu kanye nemvelo enemisebe.
