Induku yeRuby engu-100mm: I-Precision Laser Medium yezinhlelo zokusebenza zesayensi nezezimboni

Incazelo emfushane:

Induku yeruby engu-100mm iyindlela yokwandisa amandla e-laser eqinile esetshenziswa kabanzi, ebonakala ngobude bayo obubomvu obukhanyayo obungu-694.3 nm. Yakhiwe nge-corundum yokwenziwa (Al₂O₃) ehlanganiswe nama-ion e-chromium (Cr³⁺), le nduku yeruby inikeza ukuzinza okuhle kakhulu kokushisa nokukhanya, okwenza ifaneleke kakhulu ezinhlelweni ezahlukene ze-laser ezisebenzisa amandla aphansi kuya kwaphakathi. Ngobude obungu-100mm, induku yeruby ilinganisela amandla okugcina amandla kanye nomklamo ohlangene, okwenza kube lula ukuhlanganiswa okuguquguqukayo kumadivayisi e-laser ezemfundo, ezesayensi, kanye namanye amadivayisi e-laser ezimboni.

Sekungamashumi eminyaka, induku yerubi isebenza njengengxenye eyisisekelo yelaser kumalebhu optics, ukuboniswa kwelaser, kanye nezinhlelo zokuqondanisa ngokunemba. Usayizi ongu-100mm umelela ukukhetha okujwayelekile okuhambisana nobubanzi bemigodi ye-resonator. I-polish enhle kakhulu yenduku yerubi, ukukhanya okubonakalayo, kanye namandla omshini kwenza kube ukukhetha okuhlala isikhathi eside nokwethembekile ngisho nalapho kuvela ubuchwepheshe obusha.

Isimiso Sokukhiqiza

Ukukhiqizwa kwenduku yeruby kuhilela amasu athuthukile okukhulisa amakristalu njengendlela ye-Verneuil flame fusion noma indlela yokudonsa i-Czochralski. Ngesikhathi sokwenziwa, i-aluminium oxide ifakwa ukuhlushwa okunembile kwe-chromium oxide ukuze kudalwe ikristalu yeruby efanayo. Uma i-boule isikhulile, iyaqondiswa, inqunywe, bese ibunjwa ibe yinduku yeruby enobukhulu obufunwayo—100mm kulokhu.

Induku ngayinye yerubi isuke ingaphansi kwezinqubo eziqinile zokupholisha nokumboza. Ubuso bokugcina buyagoqwa futhi bupholishwe ukuze bube bushelelezi ngokwezinga le-laser (λ/10 noma ngaphezulu) futhi bungase bumbozwe ngezendlalelo ze-dielectric ezibonisa ukukhanya okuphezulu (HR) noma ezibonisa ukukhanya (AR) ukuze zivumelane nemiklamo ethile ye-laser cavity. Induku yerubi kumele ingabi nama-inclusions kanye nama-striation ukuqinisekisa ukupompa okukhanya okuqhubekayo kanye nokulahlekelwa okuncane kokusabalala.

Ama-ion e-chromium ngaphakathi kwenduku ye-ruby amunca ukukhanya kububanzi be-spectral eluhlaza/oluhlaza okwesibhakabhaka. Uma ephonswa yi-flashlamp, avuselelwa esimweni samandla aphezulu. Njengoba ebuyela esimweni sawo somhlabathi, akhipha ama-photon abomvu ahambisanayo, aqale ukusabela kweketanga lokukhishwa okushukunyisiwe—ngaleyo ndlela akhiqize umkhiqizo we-laser. Induku ye-ruby engu-100mm yenzelwe ukufeza isitoreji samandla esisebenzayo kanye nobude be-fluorescence obuhle kakhulu.

Ukusetshenziswa Kwezinduku Ze-Ruby Kuzo Zonke Izimboni

Izinduku ze-ruby, ezenziwe nge-aluminium oxide yokwenziwa eyodwa-crystal ehlanganiswe nama-ion e-chromium, ziyaziswa kakhulu ngenhlanganisela yazo eyingqayizivele yobunzima obungokwenyama, ukuzinza kwamakhemikhali, kanye nezakhiwo ezimangalisayo zokukhanya. Lezi zici zenza izinduku ze-ruby zibe yinto esezingeni eliphezulu yezinhlelo zokusebenza eziningi zezimboni, zesayensi, kanye nokunemba. Ngezansi kunemikhakha ebalulekile lapho izinduku ze-ruby ziqhubeka nokubonisa inani eliyingqayizivele:

1. Ubuchwepheshe be-Laser kanye ne-Photonics

Izinduku ze-ruby zisebenza njenge-gain medium kuma-laser e-ruby, zikhipha ukukhanya okubomvu ku-694.3 nm uma ziphampulwa ngokubonakalayo. Nakuba ezinye izindlela zesimanje ezifana ne-Nd:YAG kanye nama-laser e-fiber zibusa emakethe, ama-laser e-ruby asathandwa emikhakheni ekhethekile efana nalokhu:

Udokotela wesikhumba wezokwelapha (ukususwa kwe-tattoo kanye nezilonda)
Amathuluzi okubonisa ezemfundo
Ucwaningo lwamehlo oludinga isikhathi eside sokushaya kwenhliziyo kanye nekhwalithi ephezulu yokukhanya

Ukucaca okuhle kakhulu kokukhanya kanye nokusebenza kahle kokuguqulwa kwamandla kwe-ruby kwenza kube kuhle kakhulu ekulawuleni nasekukhipheni i-photonic okunembile.

2. Ubunjiniyela Bokucacisa kanye ne-Metrology

Ngenxa yobunzima bazo obuphezulu (isikali se-Mohs 9), izinduku ze-ruby zisetshenziswa kabanzi ezinhlelweni zokulinganisa ezisekelwe ekuthinteni, okuhlanganisa:

Amathiphu e-stylus emishinini yokulinganisa ehlanganisiwe (ama-CMM)
Ama-probe kumathuluzi okuhlola ngokunemba
Amaphuzu okubhekisela anembile kakhulu kuma-gauge optical kanye ne-mechanical

Lawa mathuluzi athembele ekumelaneni kwerubi nokuguquguquka, okuqinisekisa ukunemba kokulinganisa okuqhubekayo nokwesikhathi eside ngaphandle kokuguga.

3. Izinhlelo Zokwenza Amawashi kanye Nezinhlelo Zokubeka Ama-Micro Bearing

Ku-horology esezingeni eliphezulu, izinduku ze-ruby zicutshungulwa zibe ama-jewelry bearings—izingxenye ezincane ezinciphisa ukungqubuzana kanye nokuguguleka ekunyakazeni kwewashi lomshini. I-coefficient yazo ephansi yokungqubuzana kanye nokuqina okuphezulu kunegalelo kulokhu:

Ukusebenza kahle kwezitimela zegiya
Isikhathi eside sokuphila kwezingxenye zewashi zangaphakathi
Ukuzinza kokugcina isikhathi okuthuthukisiwe

Ngaphandle kwamawashi, izinduku zerubi nazo zisetshenziswa kuma-micro-motor, kuma-flow sensor, kanye nama-gyroscope lapho kudingeka khona ukungqubuzana nokuthembeka okuphansi kakhulu.

4. Izinhlelo Zezindiza Nezokuhlanza Imishini

Ezindaweni zezindiza, i-satellite, kanye nezindawo ezine-vacuum ephezulu, izinduku ze-ruby zisetshenziswa njengezikhala, izikhonkwane zokusekela, kanye neziqondiso ze-optical. Izinzuzo zazo ezibalulekile zifaka:

Ukuziphatha okungaphenduli kahle ezindaweni ezinolaka lwamakhemikhali
Ukumelana okuhle kakhulu nokushisa kanye nokuqina kobukhulu
Akukho ukuphazamiseka kwe-magnetic kumadivayisi azwela i-electromagnetic

Lezi zici zivumela izinduku zerubi ukuthi zisebenze kahle ngaphansi kwezimo ezimbi kakhulu, okuhlanganisa ukuchayeka emisebeni, ukushintsha kwezinga lokushisa okusheshayo, kanye nokucindezeleka kwe-vacuum.

5. Amadivayisi Okuhlaziya Nezokwelapha

Izinduku ze-ruby zidlala indima ebalulekile ekusetshenzisweni kwezinsimbi eziyinkimbinkimbi, ikakhulukazi lapho ukuhambisana kwezinto eziphilayo kanye nokungangeni kwamakhemikhali kubalulekile khona. Izicelo zifaka:

Ama-probe ane-sapphire e-spectroscopy kanye nokuxilongwa
Ama-nozzle aqondile noma izingxenye zokulawula ukugeleza kuma-analyzer
Izinduku eziqinile kakhulu emishinini yokwenza izinto ngokuzenzakalela elebhu

Ubuso bazo obuhlanzekile, obuzinzile kanye nokumelana nokugqwala kwenza zibe zilungele ukuthintana namasampula ezinto eziphilayo noma uketshezi olusabelayo.

6. Imikhiqizo Yokunethezeka Nomklamo Osebenzayo

Ngaphandle kokusebenza okumsulwa, izinduku ze-ruby ngezinye izikhathi zihlanganiswa nezibaya zobukhazikhazi, amakhampasi, izingcezu zobucwebe, kanye nezikopu ze-optical—ezisebenza njengezakhi zesakhiwo nezokuhlobisa. Umbala wazo obomvu ojulile kanye nobuso obucwebezelayo kunezela kulokhu:
