Intshayelelo: Ihlabathi Elikhanyiswa ziiLasers
Kuluntu lwezenzululwazi, izinto ezintsha ezithe zalungisa imbono yethu kunye nokusebenzisana nendalo iphela ziyahlonitshwa. I-laser ime njengenye yezinto eziqanjiweyo, ingena kwiinkalo ezininzi zobukho bethu, ukusuka kubuchule bezempilo ukuya kuthungelwano olusisiseko lonxibelelwano lwedijithali. Okungundoqo kubuchwephesha beteknoloji yelaser yinto ekhethekileyo: iglasi ye-erbium-doped. Olu phononongo lutyhila inzululwazi echulumancisayo exhasa iglasi ye-erbium kunye nokusetyenziswa kwayo okubanzi kubumba ihlabathi lethu langoku (uSmith & Doe, 2015).
Icandelo 1: Iziseko ze-Erbium Glass
Ukuqonda i-Erbium Glass
U-Erbium, ilungu lothotho lomhlaba onqabileyo, uhlala kwibhloko ye-f yetafile yeperiodikhi. Ukudityaniswa kwayo kwiimatriki zeglasi kunika iimpawu ezibonakalayo ezibonakalayo, ukuguqula iglasi eqhelekileyo ibe yindawo eyoyikekayo ekwaziyo ukulawula ukukhanya. Iqondwa ngombala opinki ohlukileyo, olu tshintsho lweglasi lubaluleke kakhulu ekukhuliseni ukukhanya, luyimfuneko kwiindlela ezahlukeneyo zokusebenzisa itekhnoloji (uJohnson & Steward, 2018).
Er, Yb:Phosphate Glass Dynamics
I-synergy ye-Erbium kunye ne-Ytterbium kwiglasi ye-phosphate yenza umqolo womsebenzi we-laser, owahlulwe nge-4 I-13/2 yenqanaba lamandla owandisiweyo kunye nokusebenza kakuhle kokutshintsha kwamandla ukusuka kwi-Yb ukuya kwi-Er.. I-Er, Yb co-doped yttrium aluminiyam borate (Er, Yb: YAB) ikristale yenye indlela eqhelekileyo ku-Er, Yb: iglasi yephosphate. Olu lwakhiwo lubalulekile kwiilaser ezisebenza ngaphakathi "iliso likhuselekile" 1.5-1.6μm spectrum, iyenza ibe yimfuneko kuyo yonke imimandla eyahlukeneyo yetekhnoloji (Patel & O'Neil, 2019).
Ukuhanjiswa kwenqanaba lamandla e-Erbium-Ytterbium
Iimpawu eziphambili:
Yandisiwe 4 I 13/2 ubude benqanaba lamandla
Uphuculo lwe-Yb ukuya kwi-Er luguqulo lwamandla olusebenzayo
Iiprofayili zokufunxa ngokupheleleyo kunye nokukhupha
Inzuzo ye-Erbium
Ukhetho lwe-Erbium lwenziwe ngabom, luqhutywa luqwalaselo lweatom olunceda ukufunxa ukukhanya kunye nokuphuma kobude bamaza. Le photoluminescence ibalulekile ekuveliseni ukukhutshwa kwelaser okunamandla, okuchanekileyo.
IiLasers zibonisa umtshato ohambelanayo phakathi kwesayensi kunye netekhnoloji, ubungqina bokukwazi kwethu ukonyusa imithetho yendalo kumalinge oovulindlela. Apha, iintsimbi zomhlaba ezinqabileyo, ngakumbi i-erbium (Er) kunye ne-ytterbium (Yb), ziyalela indima esembindini ngenxa yeempawu zazo zefotonic ezingenakulinganiswa.

Icandelo 2: Iglasi ye-Erbium kwiTekhnoloji yeLaser
Ukucacisa oomatshini beLaser
Ngokusisiseko, i-laser sisixhobo esihambisa ukukhanya nge-optical amplification, ngokuxhomekeke kukuziphatha kwe-electron ngaphakathi kwee-athomu ezithile, kuquka i-erbium. Ezi electron, xa zifunxa amandla, zinyukela kwindawo "echulumancisayo", emva koko zikhuphe amandla njengamasuntswana okukhanya okanye iifotoni, ilitye lembombo lokusebenza kwelaser.
Iglasi yeErbium: Intliziyo yeeNkqubo zeLaser
I-Erbium-doped fiber amplifiers(Ii-EDFAs) zibalulekile kuthungelwano lwehlabathi jikelele, luququzelela ukuhanjiswa kwedatha kwimigama ebanzi ngokuthotywa okungahoywanga. Ezi amplifiers zisebenzisa iimpawu ezingaqhelekanga zeglasi ye-erbium-doped ukuqinisa imiqondiso yokukhanya ngaphakathi kwe-fiber optic conduits, impumelelo echazwe ngokubanzi nguPatel & O'Neil (2019).

Icandelo 3: Ukusetyenziswa okuSebenzayo kwe-Erbium Glass
Iglasi yeErbiumUkusetyenziswa kwepragmatic kunzulu, kutyhutyha amacandelo amaninzi aquka, kodwa kungaphelelanga apho, kuthungelwano, ukuvelisa, kunye nokhathalelo lwempilo.
Ukuguqula unxibelelwano
Kwilathisi entsonkothileyo yeenkqubo zonxibelelwano zehlabathi, iglasi ye-erbium ibalulekile. Ubunganga bayo bokukhulisa inciphisa ilahleko yomqondiso, iqinisekisa ngokukhawuleza, ukuhanjiswa kolwazi olubanzi, ngaloo ndlela kuncipha ulwahlulo lwehlabathi kunye nokukhuthaza unxibelelwano lwexesha lokwenyani.
Ubuvulindlela Inkqubela-phambili Kwezonyango NezoShishino
Iglasi yeErbiumlugqithisa unxibelelwano, ukufumana i-resonance kwiinkalo zonyango kunye nezoshishino. Kukhathalelo lwempilo, izikhokelo zayo ezichanekileyo zikhokela iilaser zotyando, ezinikezela ngeendlela ezikhuselekileyo, ezingaphazamisiyo kwiindlela eziqhelekileyo, isifundo esiphononongwe nguLiu, Zhang, & Wei (2020). Kwimizi-mveliso, iluncedo kubuchule bokwenza obuphambili, ukuqhubela phambili ukuveliswa kwezinto ezintsha kwiinkalo ezifana ne-aerospace kunye ne-elektroniki.
Ukuqukumbela: Ikamva Elikhanyisiweyo Ngembeko kaIglasi yeErbium
Ukuvela kweglasi ye-Erbium ukusuka kwinto esoteric ukuya kwilitye lembombo letekhnoloji yale mihla ibonisa ubuchule bomntu. Njengoko sisophula imida emitsha yenzululwazi kunye netekhnoloji, usetyenziso lweglasi ye-erbium-doped ebonakalayo ibonakala ingenamda, ibhengeza ikamva apho imimangaliso yanamhlanje ingamatye akhokelela kwimpumelelo engathethekiyo yangomso (Gonzalez & Martin, 2021).
