Intshayelelo: Ihlabathi Elikhanyiswe YiLaser
Kwinzululwazi yoluntu, izinto ezintsha ezitshintshe indlela esibona ngayo kunye nokusebenzisana kwethu nendalo iphela ziyahlonitshwa. I-laser imi njengenye yezinto ezintsha ezibalulekileyo, ingena kwiinkalo ezininzi zobomi bethu, ukusuka kwiingxaki zempilo ukuya kwiinethiwekhi ezisisiseko zonxibelelwano lwethu lwedijithali. Eyona nto iphambili kubuchule betekhnoloji ye-laser yinto ebalaseleyo: iglasi exutywe ne-erbium. Olu phononongo lutyhila isayensi enomdla exhasa iglasi ye-erbium kunye nezicelo zayo ezibanzi ezibumba ihlabathi lethu lanamhlanje (Smith & Doe, 2015).
Icandelo 1: Iziseko zeGlasi ye-Erbium
Ukuqonda iGlasi ye-Erbium
I-Erbium, ilungu le-rare earth series, ihlala kwi-f-block yetafile ye-periodic. Ukuhlanganiswa kwayo kwi-glass matrices kubonakalisa iimpawu ezibonakalayo ezibonakalayo, kuguqula iglasi eqhelekileyo ibe yindawo enamandla yokulawula ukukhanya. Ibonakala ngombala opinki owahlukileyo, olu hlobo lweglasi lubaluleke kakhulu ekukhuliseni ukukhanya, lubalulekile kwimisebenzi eyahlukeneyo yetekhnoloji (Johnson & Steward, 2018).
Er, Yb:Phosphate Glass Dynamics
Ukusebenzisana kwe-Erbium kunye ne-Ytterbium kwiglasi ye-phosphate kwenza umqolo womsebenzi we-laser, owahlulwe bubomi obongezelelweyo benqanaba lamandla le-4 I 13/2 kunye nokusebenza kakuhle kotshintsho lwamandla ukusuka kwi-Yb ukuya kwi-Er.. Ikristale ye-Er, Yb exutywe ne-yttrium aluminium borate (Er, Yb: YAB) yindlela eqhelekileyo yokukhetha iglasi ye-phosphate endaweni ye-Er, Yb:Olu lwakhiwo lubalulekile kwiilaser ezisebenza ngaphakathi "ekhuselekileyo emehlweni"1.5-1.6"μi-m spectrum, nto leyo eyenza ukuba ibe yinto ebalulekileyo kwiindawo ezahlukeneyo zobuchwepheshe (uPatel kunye no-O'Neil, 2019).
Ukusasazwa kwenqanaba lamandla e-Erbium-Ytterbium
Iimpawu eziphambili:
Ubude benqanaba lamandla elongeziweyo le-4 I 13/2
Ukusebenza kakuhle kotshintsho lwamandla oluphuculweyo ukusuka kwi-Yb ukuya kwi-Er
Iiprofayili ezipheleleyo zokufunxa kunye nokukhupha
Inzuzo ye-Erbium
Ukukhetha kwe-Erbium kwenziwe ngabom, kuqhutywa bubume beathom obuvumela ukufunxwa kokukhanya okufanelekileyo kunye namaza okukhanya. Olu kukhanya kwe-photoluminescence lubalulekile ekuveliseni ukukhutshwa kwe-laser okunamandla nokuchanekileyo.
Iilaser zibonisa umanyano oluhambelanayo phakathi kwesayensi netekhnoloji, ubungqina bokukwazi kwethu ukusebenzisa imithetho yendalo kwiindlela zokuqala amashishini. Apha, iintsimbi zomhlaba ezinqabileyo, ngakumbi i-erbium (Er) kunye ne-ytterbium (Yb), zidlala indima ephambili ngenxa yeempawu zazo ze-photonic ezingenakuthelekiswa nanto.

Icandelo 2: Iglasi ye-Erbium kwiTekhnoloji yeLaser
Ukuchaza iiMechanics zeLaser
Ngokusisiseko, i-laser sisixhobo esiqhuba ukukhanya nge-optical amplification, exhomekeke kwizenzo ze-electron ngaphakathi kwee-athomu ezithile, kuquka ne-erbium. Ezi electron, xa zifunxwa ngamandla, zinyukela kwimeko "yovuyo", emva koko zikhuphe amandla njengee-particles zokukhanya okanye ii-photons, isiseko somsebenzi we-laser.
Iglasi ye-ErbiumIntliziyo yeNkqubo yeLaser
Izikhulisi zefayibha ezifakwe i-Erbium(ii-EDFA) zibalulekile kunxibelelwano lwehlabathi liphela, zinceda ukudluliselwa kwedatha kumgama omde kunye nokuwohloka okuncinci. Ezi amplifiers zisebenzisa iimpawu ezingaqhelekanga zeglasi efakwe i-erbium ukuqinisa imiqondiso yokukhanya ngaphakathi kwee-fiber optic conduits, impumelelo echazwe ngokubanzi nguPatel & O'Neil (2019).

Icandelo 3: Ukusetyenziswa Okusebenzayo kweGlasi ye-Erbium
Iglasi ye-ErbiumUkusetyenziswa okusebenzayo kunzulu, kugubungela amacandelo amaninzi kuquka, kodwa kungaphelelanga apho, unxibelelwano, imveliso, kunye nokhathalelo lwempilo.
Ukuguqula uNxibelelwano
Ngaphakathi kwe-lattice eyinkimbinkimbi yeenkqubo zonxibelelwano zehlabathi, iglasi ye-erbium ibalulekile. Amandla ayo okukhulisa anciphisa ukulahleka kwesignali, ukuqinisekisa ukudluliselwa kolwazi ngokukhawuleza nangokubanzi, ngaloo ndlela kunciphisa ukwahlukana kwehlabathi kwaye kukhuthaza unxibelelwano ngexesha langempela.
Ukuqalisa inkqubela phambili kwezonyango nakwimizi-mveliso
Iglasi ye-Erbiumidlula unxibelelwano, ifumana ingxolo kwiinkalo zonyango nakwimizi-mveliso. Kwinkonzo yezempilo, ukuchaneka kwayo kukhokela ii-laser zotyando, inikezela ngezinye iindlela ezikhuselekileyo, ezingaphazamisiyo kwiindlela eziqhelekileyo, umxholo ophononongwe nguLiu, Zhang, kunye noWei (2020). Kwishishini, iluncedo kwiindlela zokuvelisa eziphambili, ikhuthaza uphuhliso kwiinkalo ezifana neenqwelo moya kunye ne-elektroniki.
Isiphelo: Ikamva Elikhanyisiweyo Ngembeko kaIglasi ye-Erbium
Ukuguquka kweglasi ye-Erbium ukusuka kwinto engabonakaliyo ukuya kwinto yesiseko yeteknoloji yanamhlanje kubonisa ubuchule bomntu. Njengoko siphula imiqathango emitsha yesayensi neteknoloji, ukusetyenziswa kweglasi exutywe ne-erbium kubonakala kungenamkhawulo, kuxela ikamva apho imimangaliso yanamhlanje ingamatye okuya kwimpumelelo engenakulinganiswa yekamva (Gonzalez & Martin, 2021).
