Asazi ngobuchwepheshe be-laser
Asazi ngobuchwepheshe be-laser, i-1960 yayiwukuphela kokukhiqizwa kwe-laser okuphumelelayo.Endabeni ye-laser ukulungiswa kwethiyori kanye nemikhuba yokukhiqiza isizinda esidingekayo esiphuthumayo savela, saphuma, ukuze sithole ukuthuthukiswa okusheshayo okungavamile, hhayi nje ukuthuthukiswa kwe-laser ukuze isayensi yasendulo ye-optical and optical technologies izuze impilo entsha, kodwa futhi kuholele ekuveleni komnyango omusha wemboni.I-laser yomshini wokusika i-laser yenza abantu bakwazi ukusebenzisa ngempumelelo izindlela ezithuthukile ezingakaze zibonwe ngaphambili, ukuze bathole izinzuzo nemiphumela engakaze ibonwe, ukuze kuthuthukiswe ukuthuthukiswa kwamandla okukhiqiza.
Kodwa-ke, njengokusika kwe-laser laser, i-laser welding, umshini wokusika we-laser bekulokhu ukusetshenziswa kabanzi kokuphila phakathi kokukhiqizwa, kodwa futhi ne-laser crystal, i-laser terahertz ulwazi olunjalo, asivamile ukuthintana nomlobi walesi sihloko kuholele wonke umuntu ukuthi abheke labo esingabazi. ujwayelene nobuchwepheshe be-laser.
Umshini wokusika i-laser i-laser crystal energy inganikezwa yi-optical cavity yangaphandle ekuhambisaneni kwendawo kanye nesikhashana ezintweni ze-crystalline zihambisana kakhulu kanye nokukhanya kwe-laser monochromatic.Izinto zokusebenza yi-crystal laser.I-laser crystal yizikhungo ze-luminescence kanye namakristalu e-matrix akhiwe izingxenye ezimbili.Iningi lesikhungo esikhipha ukukhanya ngokwenza kusebenze isakhiwo sekristalu ye-ion laser, ama-ion asebenzayo athathelwe indawo kancane amakristalu e-cation matrix amakristalu ane-laser.Uma wenza kusebenze i-ion iba yingxenye yezingxenye zekristalu engumsingathi, ihlanganisa ikristalu ye-laser ezisebenza yona.
Ikristalu ye-laser yomshini wokusika isetshenziswa ikakhulukazi kuma-ion ensimbi enguquko ye-ionic kanye nama-ion angavamile emhlabeni.I-Optical electronic transition metal ions ikusendlalelo sangaphandle sama-electron angu-3 d kumakristalu anjalo i-optical electronic esengozini yomphumela oqondile we-crystal field nxazonke, ngakho-ke izinhlobo ezahlukene ze-crystal structure, izici zayo ze-spectral zihluke kakhulu.I-Trivalent Earth Rare ions 4 F electrons ivikela umphumela wama-electron angu-5 no-5 p, ukuze inkambu yekristalu ibe buthakathaka indima yayo, kodwa indima ye-crystal field perturbation izimbangela ziye zanqatshelwa 4 f ukuguqulwa kwama-electron kungenzeka ukukhiqiza ukumuncwa okuncane kanye nomugqa we-fluorescence.Ngakho-ke ama-ion e-trivalent-earth ayivelakancane ku-spectra yama-ion ensimbi eshintshashintshayo eyikristalu afana noshintsho olukhulu.
