Yini i-Laser

I-Laser ilula ikhuliswa ngokumunca amandla akhazimulayo.Imisebe ye-laser ikhiqizwa umthombo we-laser, futhi amandla asondelene kakhulu ajabulisa izinduku zekristalu (ama-laser esifunda esiqinile) noma izingxube zegesi ezikhethekile.  (ama-laser wegesi) ukukhiqiza imisebe ye-laser.Lawa mandla anikezwa ngendlela yokukhanya (isibani esikhanyayo noma i-laser diode) noma ukukhishwa kukagesi (okulingana nesibani se-fluorescent).Induku yekristalu noma  igesi eyenziwe nge-laser itholakala phakathi kwezibuko ezimbili ukuze yenze i-laser resonant cavity ukuze iqondise i-laser endaweni ethile futhi ikhulise isignali yokubona ngale ndlela.I-laser iyadlula  ngesibuko esisobala ngengxenye ethile futhi sisetshenziselwa ukucubungula impahla.    Izimiso Laser Processing

Wonke ama-laser aqukethe lezi zingxenye ezintathu ezilandelayo: Umthombo wepompo Ophakathi nendawo ovuselelwe Isikhala esizwakalayo Umthombo wepompo unikeza amandla asuka emthonjeni wangaphandle aye kulaser.I-medium ejabulile itholakala ngaphakathi kwe-laser.Ngokuya ngomklamo wesakhiwo se-laser, i-laser medium ingaba ingxube yegesi (CO2 laser), i-crystal rod (YAG solid laser) noma i-glass fiber.  (i-fiber laser).Lapho i-laser medium inikezwa amandla avela emthonjeni wephampu wangaphandle, kuyajabulisa ukukhiqiza imisebe yamandla.I-medium ejabulile itholakala phakathi kwezibuko ezimbili kuzo zombili iziphetho ze-resonant cavity.Esinye sezibuko siyilensi yendlela eyodwa (isigamu sesibuko).I-radiation yamandla ekhiqizwa yi-  i-medium ejabulile ikhuliswa ku-resonant cavity.Ngesikhathi esifanayo, kukhona eyodwa kuphela ethize Imisebe ingadlula kulensi yendlela eyodwa ukuze yakhe umsebe wemisebe, okuyi-radiation.  laser.

I-Laser inezici ezintathu eziyinhloko:Ukufana: imisebe ye-laser iqukethe ubude begagasi obubodwa bokukhanya Ukuhambisana: isigaba esifanayo Ukufana: Ukukhanya kwe-laser beam kuhambisana kakhulu Ukukhanya kwe-laser kuhambisana kakhulu ngaphambi kokudlula kulensi egxilile.Ngaphakathi kobude bokugxila be-laser beam, kukhiqizwa amandla aphezulu kakhulu, angasetshenziswa ukuncibilikisa noma ukuhwamuka kwezinto.Ngaphezu kwalokho, ukusetshenziswa kwezinto ezifanele ze-optical (ama-lens) kungaqondisa futhi kubonise ukukhanya kwe-laser, futhi ngeke kube nokulahlekelwa ngisho nakude.Isistimu yokumisa (isikhombi se-laser) noma isithwebuli se-galvanometer sisetshenziswa njengesistimu yeselula.Njengoba i-laser beam ngeke idluliswe, leli ithuluzi elivamile, elingagugi.
