Asazi ngobuchwephesha belaser
Asazi ngetekhnoloji yelaser, i-1960 yayiyeyona mveliso yokuqala yelaser eyimpumelelo.Kwimeko ye-laser kukulungiswa kwethiyori kunye nezenzo zemveliso ezifunekayo ngokungxamisekileyo kwavela imvelaphi, yaphuma, ukufumana uphuhliso olukhawulezayo olungaqhelekanga, kungekuphela nje uphuhliso lwelaser ukuze isayensi yakudala ye-optical technology kunye ne-optical technologies izuze ubomi obutsha, kodwa ikwakhokelela ekuveleni komnyango omtsha weshishini.I-laser yomatshini wokusika i-laser yenza abantu basebenzise ngokufanelekileyo iindlela ezingazange zibonwe ngaphambili kunye neendlela, ukufumana izibonelelo ezingazange zibonwe ngaphambili kunye neziphumo, ukuze kukhuthazwe uphuhliso lwamandla okuvelisa.
Nangona kunjalo, njengokusika kwe-laser laser, i-laser welding, umatshini wokusika i-laser ibikukusetyenziswa ngokubanzi kobomi phakathi kwemveliso, kodwa kunye ne-laser crystal, i-laser terahertz ulwazi olunjalo, kunqabile ukuba siqhagamshelane nombhali weli nqaku sikhokele wonke umntu ukuba ajonge ezo singaziboniyo. uqhelene neteknoloji laser.
Umatshini wokusika umatshini we-laser amandla ekristale unokubonelelwa ngumgodi wangaphandle we-optical kwi-spatial kunye nokuhambelana kwexeshana kwizinto ze-crystalline zihambelana kakhulu kunye nokukhanya kwe-laser monochromatic.Izinto ezisebenzayo yi-crystal laser.Ikristale yeLaser ngamaziko e-luminescence kunye neekristale zematrix ezenziwe ngamacandelo amabini.Uninzi lweziko elikhupha ukukhanya ngokuvula i-ion laser crystal structure, ii-ion ezisebenzayo ngokuyinxenye endaweni ye-cation matrix crystals doped laser crystals.Xa uvula i-ion iba yinxalenye yamacandelo ekristale yomkhosi, yenza ikristale yelaser ezenzelayo.
Umatshini wokusika umatshini we-laser wekristale osetyenziswa ikakhulu kwi-ion yensimbi ye-ionic esebenzayo kunye ne-trivalent ion-earth earth.Optical electronic transition metal ion ikwimaleko yangaphandle 3 d electron kwiikristale ezifana optical electronic sesichengeni isiphumo ngqo intsimi yikristale ngeenxa zonke, ngoko ke iintlobo ezahlukeneyo zekristale isakhiwo, iimpawu zayo spectral zahluke kakhulu.Ii-ion zomhlaba ezinqabileyo ezi-4 4 f electrons zikhusela umphumo 5 s kunye ne-5 p elektroni zangaphandle, ukuze intsimi yekristale ibe buthathaka yendima yayo, kodwa indima ye-crystal field perturbation izizathu ziye zalelwa 4 f iinguqu ze-electron ziyakwazi ukuvelisa ukufunxa emxinwa. kunye nomgca we-fluorescence.Ke ii-ion ze-trivalent-earth-earth kwi-spectra ye-crystal transition ye-ion yesinyithi eyahlukeneyo efana nokutshintsha kakhulu.
