Ushuni we-laser uyisikhungo esiyinkimbinkimbi esisebenzisa umgqomo wokukhanya ogxilile ukusika, ukubaza, ukumaka, noma ukushisela izinto ngokunemba okungajwayelekile. Igama elithi "laser" limele i-Light Amplification by Stimulated Emission of Radiation, futhi lezi zinjini ziye zavuselela ukukhiqizwa kwesimanje ngokuletha ukunemba okungafaniswa nezindlela zakudala. Ubuchwepheshe busebenza ngokukhiqiza umgqomo wokukhanya ohlangene okhuliswa futhi ugxiliswe ngohlelo lwezibonelo endaweni encane kakhulu, kudale ukushisa okunamandla okuncibilikisa, ukushisa, noma ukuvusa umoya into. Le nqubo ivumela abasebenzisi ukuthi bafeze imiklamo eyinkimbinkimbi namalungiselelo aqinile ezinhlobonhlobo zezinto, kusuka emithanjeni namapulasitiki kuya emithini ne-ceramics. Ukuqonda ukuthi umshini we-laser usebenza kanjani kuyisinyathelo sokuqala sokubonga indima yawo ezimbonini ezisukela ezindizeni kuya ekukhiqizeni izinto zokwelapha.

Umlando wobuchwepheshe be-laser uqala ngo-1960 lapho uTheodore Maiman wakha i-laser yokuqala esebenzayo esebenzisa ikristalu ye-ruby eyenziweyo. Emashumini eminyaka alandela, abacwaningi bakha ama-laser egasi, ama-laser esimo esiqinile, futhi ekugcineni ama-laser efayibha, ngayinye yalezi zinguquko iletha ukuthuthukiswa emandleni, ukusebenza kahle, nokusebenza ngezindlela ezahlukahlukene. Ngeminyaka yawo-1980, ukusika ngama-laser ezimbonini kwaba nenzuzo kwezentengiselwano, futhi namuhla imishini ye-laser iyatholakala ezimbonini, emagumbini okusebenzela, ngisho nasezinkampanini ezincane emhlabeni wonke. Lolu shintsho luqhutshwa isidingo sezivinini zokukhiqiza ezisheshayo, izindleko zokusebenza eziphansi, kanye nekhono lokusebenza ngezinto eziba nzima kakhulu. Ngenxa yalokho, imishini yanamuhla ye-laser isibe amathuluzi abalulekile ekukhiqizeni okunembayo, okwenza konke kusukela ekwenzeni izinto eziklanywe ngendlela efanele kuze kube sekukhiqizeni okuningi.

Imishini ye-laser iza ngezinhlobo eziningana ezihlukene, ngayinye inezici ezihlukile ezizenza zilungele izicelo ezithile. Izigaba ezintathu ezivame kakhulu yi-CO2 lasers, i-fiber lasers, kanye ne-diode lasers, futhi ukuqonda umehluko wazo kubalulekile lapho ukhetha imishini yomsebenzi othile. I-CO2 lasers isebenzisa inhlanganisela yegesi ye-carbon dioxide, i-nitrogen, ne-helium njengendawo yokuthola inzuzo, ikhiqiza ubude bamagagasi obungaba ngu-10.6 micrometers obusebenza kahle kakhulu ekusikeni izinto ezingewona amatshe njengokhuni, i-acrylic, indwangu, namapulasitiki. I-fiber lasers, ngakolunye uhlangothi, isebenzisa izintambo zokukhanya ezinezingxenye ezingavamile njenge-ytterbium ukukhiqiza umgqomo ongaba ngu-1.07 micrometers, okumuncwa kahle kakhulu amatshe. I-diode lasers yizinto eziqinile eziguqula amandla kagesi ngqo abe ukukhanya, zinikeza usayizi omncane nokusetshenziswa kwamandla okuphansi kwezicelo njengokugravisha nokumaka.

Uma kuqhathaniswa ama-laser e-CO2 nama-laser e-fiber nama-laser e-diode, umehluko oyinhloko ulele ekusebenzeni kwe-beam, izidingo zokugcinwa, kanye nokuhambisana kwezinto. Ama-laser e-CO2 avame ukudinga ukugcinwa njalo ngoba amashubhu egasi ayabola ngokuhamba kwesikhathi futhi izibuko zidinga ukuhlanjululwa njalo, kodwa ayaphumelela ekusikeni izinto eziwugqinsi ezingewona amatshe futhi akhiqize ukuqedwa komphetho okubushelelezi. Ama-laser e-fiber anesikhathi eside sokuphila, avame ukudlula amahora angu-100,000 okusebenza, futhi ahlinzeka ngamandla kagesi aphezulu, okusho ukuthi izikweletu zikagesi eziphansi kumsebenzisi. Ama-laser e-diode ayindlela engabizi kakhulu ekuqaleni futhi afanele imisebenzi enamandla aphansi njengokumaka upulasitiki noma i-aluminum ye-anodized, nakuba ngokuvamile engeke abe namandla adingekayo ekusikeni insimbi ewugqinsi. Ezinkampanini ezifuna isixazululo esiguquguqukayo nesihlala njalo, ama-laser e-fiber abe yisinqumo esiphambili ekwenziweni kwemishini yesimanje ngenxa yokwethenjwa kwawo kanye nezindleko eziphansi zokuba nawo.

Isisihleli se-fiber laser siqukethe izinhlelo eziyinhloko ezintathu: umthombo we-laser, umhlangano we-optics, kanye nohlelo lokulawula ukunyakaza. Umthombo we-laser uyinhliziyo yomshini, lapho ama-diode okumpompa afaka khona ukukhanya kufayibha ye-optical enezinto ezingajwayelekile, futhi izakhi ezingajwayelekile ngaphakathi kwefayibha zikhuphula lokho kukhanya kube ububanzi obunamandla obuhlangene. Lobubanzi bese buhamba ngomugqa wama-lenses nezibuko—okubizwa ngokuthi i-beam delivery optics—ezihlela futhi ziqondise ukukhanya ekhanda lokusika. Ikhanda lokusika liqukethe i-lens yokugxilisa eyenza ububanzi buhlangane kube usayizi omncane kakhulu, ovame ukuba ngaphansi kuka-0.1 millimeters ububanzi, okwenza amandla adlule i-watts eyisigidi esisodwa nge-centimeter square.
