Iikristale zeLaser kunye namacandelo azo zizinto eziphambili ezisisiseko kwishishini le-optoelectronics. Ikwayinxalenye ephambili yeelaser zombuso oqinileyo ukuvelisa ukukhanya kwelaser. Ngokujonga iingenelo zokufana okuhle kwe-optical, iipropathi ezilungileyo zoomatshini, uzinzo oluphezulu lomzimba kunye neekhemikhali, kunye nokuhanjiswa okuhle kwe-thermal, iikristale zelaser zisezizixhobo ezidumileyo kwiilaser zombuso oqinileyo. Ke ngoko, isetyenziswa kakhulu kwimizi-mveliso, kwezonyango, kuphando lwezenzululwazi, kunxibelelwano nakumashishini omkhosi. Njengokuqala kwelaser, isalathisi sethagethi yelaser, ukubhaqwa kwelaser, ukumakishwa kwelaser, ukusika i-laser (kubandakanya ukusika, ukomba, ukuwelda kunye nokukrola, njl.njl.), unyango lwelaser, kunye nobuhle belaser, njl.
I-Laser ibhekisela ekusetyenzisweni kwamasuntswana amaninzi kwizinto zokusebenza kwimeko echulumancisayo, kunye nokusetyenziswa kokufakwa kokukhanya kwangaphandle ukwenza zonke iinqununu ezikwimo evuyayo zizalise i-radiation evuselelweyo ngexesha elifanayo, ukuvelisa i-beam enamandla. I-Lasers inolwalathiso oluhle kakhulu, i-monochromaticity kunye nokuhambelana, kwaye ngenxa yezi mpawu, isetyenziswa ngokubanzi kuzo zonke iinkalo zoluntu.
Ikristale yelaser inamacandelo amabini, enye yi-ion esebenzayo njenge "luminescence center", kwaye enye yikristale yomkhosi "njengomthwali" we-ion esebenzayo. Okubaluleke ngakumbi phakathi kweekristale zomkhosi ziikristale zeoksidi. Ezi kristale zineenzuzo ezizodwa ezifana nenqanaba eliphezulu lokunyibilika, ubunzima obuphezulu kunye nokuhanjiswa kakuhle kwe-thermal. Phakathi kwazo, i-ruby kunye ne-YAG zisetyenziswa kakhulu, kuba iziphene zabo ze-lattice zinokufunxa ukukhanya okubonakalayo kuluhlu oluthile lokubonisa umbala othile, ngaloo ndlela kuqondwa i-oscillation ye-laser.
Ukongeza kwii-laser zekristale zemveli, iikristale ze-laser nazo zikhula kumacala amabini: ultra-enkulu kunye ne-ultra-encinci. I-crystal lasers enkulu kakhulu isetyenziswa kakhulu kwi-laser nuclear fusion, ukwahlula i-laser isotope, ukusika i-laser kunye namanye amashishini. Iilaser zekristale ezincinci kakhulu zibhekisa ikakhulu kwiilaser zesemiconductor. Ineenzuzo zokumpompa okuphezulu, umthwalo omncinci we-thermal wekristale, imveliso ye-laser ezinzileyo, ubomi obude, kunye nobungakanani obuncinci be-laser, ke inethemba elikhulu lophuhliso kwizicelo ezithile.
