100mm Ruby Rod: Nzira Yakakodzera yeLaser yeZvishandiso zveSainzi neMaindasitiri
Dhayagiramu Yakadzama
Nhanganyaya
Tsvimbo yeruby ye100mm imhando inoshandiswa zvakanyanya ye solid-state laser gain medium, inozivikanwa nehupamhi hwayo hwema red emission wavelength pa 694.3 nm. Yakagadzirwa kubva ku synthetic corundum (Al₂O₃) yakashongedzwa ne chromium ions (Cr³⁺), iyi tsvimbo yeruby inopa kugadzikana kwakanaka kwekupisa uye optical, zvichiita kuti ive yakakodzera kune akasiyana masystem e laser ane simba shoma kusvika pakati. Nehurefu hwe100mm, tsvimbo yeruby inoenzanisa kugona kwekuchengetedza simba uye dhizaini diki, zvichiita kuti isanganiswe mumidziyo ye laser yedzidzo, yesainzi, uye yeindasitiri.
Kwemakumi emakore, ruby rod yave ichishandiswa sechikamu chakakosha chelaser mumalabhoritari ekuona, maratidziro elaser, uye masisitimu ekururamisa akakodzera. Saizi ye100mm inomiririra sarudzo yakajairika inokodzera mhando dzakasiyana dzemaburi e resonator. Ruby rod yakanaka kwazvo yekupenya kwepamusoro, kujeka kwemaziso, uye simba remakanika zvinoita kuti ive sarudzo inogara kwenguva refu uye yakavimbika kunyangwe matekinoroji matsva achibuda.
Nheyo yekugadzira
Kugadzirwa kweruby rod kunosanganisira nzira dzepamusoro dzekurima crystal dzakadai seVerneuil flame fusion method kana Czochralski pulling method. Panguva yekugadzira, aluminum oxide inosanganiswa ne chromium oxide chaiyo kuti igadzire ruby crystal yakafanana. Kana boule yakura, inonamirwa, inochekwa, uye inoumbwa kuita ruby rod yehukuru hwaidiwa—100mm mune iyi kesi.
Tsvimbo yega yega yeruby inozonyatso gadziriswa nekukweshwa. Kumagumo kwayo kunokweshwa uye kukweshwa kusvika yave yakatsetseka (λ/10 kana kupfuura) uye inogona kuputirwa ne high-reflectivity (HR) kana anti-reflective (AR) dielectric layers kuti ikwane magadzirirwo chaiwo e laser cavity. Tsvimbo yeruby haifanirwe kunge iine inclusions uye striations kuti ive nechokwadi chekuti optical pumping inogara iripo uye kuti ishoma kurasikirwa nekupararira.
Ma chromium ions ari muruby rod anotora chiedza mugreen/blue spectral range. Kana achipombwa neflashlight, anofara kusvika pakuva nesimba rakawanda. Paanodzokera kuground state yawo, anoburitsa coherent red photons, zvichitanga chain reaction ye stimulated emission—zvichiburitsa laser output. Ruby rod ye100mm yakagadzirwa kuti iwane kuchengetedza simba zvakanaka uye nguva yakakwana ye fluorescence.

Mashandisirwo eRuby Rods Mumaindasitiri Ese
Ruby rods, dzakagadzirwa kubva mu single-crystal aluminum oxide yakagadzirwa ne chromium ions, dzinokosheswa zvikuru nekuda kwekuoma kwadzo, kugadzikana kwemakemikari, uye hunhu hwadzo hwemaziso hunoshamisa. Hunhu uhwu hunoita kuti ruby rods ive chinhu chepamusoro-soro chekushandiswa kwakasiyana-siyana kwemaindasitiri, sainzi, uye kunyatsojeka. Heano mamwe masevhisi akakosha uko ruby rods dzichiri kuratidza kukosha kwakanyanya:
1. Tekinoroji yeLaser nePhotonics
Ruby rods dzinoshanda senzira yekuwana simba mumaruby lasers, dzichiburitsa chiedza chitsvuku pa694.3 nm kana dzichishandiswa ne optically. Kunyange hazvo dzimwe nzira dzemazuva ano dzakadai seNd:YAG uye fiber lasers dziri kutonga pamusika, ruby lasers dzichiri kufarirwa muminda yehunyanzvi yakadai se:
-
Kurapa kweganda (kubvisa tattoo nekukuvadzwa kweganda)
-
Zvishandiso zvekuratidzira zvedzidzo
-
Kutsvagurudza kwemaziso kunoda nguva refu yekurova kwemoyo uye mhando yepamusoro yemwaranzi
Ruby, kujeka kwakanaka kwemaziso uye kushanda zvakanaka kweruby pakushandura simba, zvinoita kuti ive yakakodzera pakudzora uye kuburitsa chiedza chakajeka.
2. Uinjiniya Hwakarurama uye Metrology
Nekuda kwekuoma kwazvo (Mohs scale 9), ruby rods dzinoshandiswa zvakanyanya mumasystem ekuyera akavakirwa pakubata, anosanganisira:
-
Matipi ekunyora mumichina yekuyera yakarongeka (CMMs)
-
Mapurofiti ari muzvishandiso zvekuongorora zvakarurama
-
Nzvimbo dzekutarisa dzakanyatsojeka mumagetsi ekuona uye emakanika
Zvishandiso izvi zvinovimba nekusagadzikana kwerubhi pakuchinjika, zvichiita kuti kuyerwa kwacho kugare kwenguva refu pasina kusakara.
3. Kugadzira Wachi uye Kugadzira Mabheyaringi Madiki
Mukuongorora kwemhando yepamusoro, matombo eruby anogadzirwa kuita mabheyaringi ematombo anokosha—zvinhu zvidiki zvinoderedza kukweshana uye kupera kwekufamba kwewachi dzemakanika. Kukweshana kwavo kushoma kwekukweshana uye kuomarara kwakanyanya kunobatsira ku:
-
Kushanda zvakanaka kwezvitima zvegiya
-
Nguva yakareba yezvikamu zvewachi zvemukati
-
Kugadzikana kwekuchengetedza nguva kwakagadziridzwa
Kupfuura mawachi, ruby rods dzinoshandiswawo muma micro-motors, flow sensors, uye gyroscopes uko kukweshana kwakaderera uye kuvimbika kunodiwa.
4. Masisitimu emuchadenga uye ekuchenesa mhepo
Munzvimbo dzine vacuum yakawanda, satellite, uye munzvimbo dzine vacuum yakawanda, ruby rods dzinoshandiswa se spacers, support pins, uye optical guides. Zvakanakira zvikuru zvinosanganisira:
-
Maitiro asingashande zvakanaka munzvimbo dzine makemikari akasimba
-
Kudzivirira kupisa kwakanyanya uye kugadzikana kwakaenzana
-
Kukanganiswa kwemagineti kwemidziyo inonzwa magetsi
Zvinhu izvi zvinoita kuti ruby rods dzishande zvakanaka mumamiriro ezvinhu akaoma, kusanganisira kuratidzwa nemwaranzi, kuchinja kwekushisa nekukurumidza, uye kumanikidzwa kwevacuum.
5. Zvishandiso zvekuongorora uye zvekurapa
Ruby rods dzinoita basa rakakosha mukugadzira zvishandiso zvine hunyanzvi, kunyanya kana kushanda pamwe chete uye kusashanda kwemakemikari kwakakosha. Mashandisirwo anosanganisira:
-
Mapurobhu ane muromo wesafire mukuongorora nekuongorora chirwere
-
Manozzle chaiwo kana zvikamu zvekudzora kuyerera kwemvura muma analyzer
-
Matavi akasimba muzvishandiso zvekushandisa otomatiki murabhoritari
Pamusoro padzo pakachena, pakasimba uye pakudzivirira ngura zvinoita kuti dzikwanise kusangana nesamples dzemuviri kana mvura dzinoshanda.
6. Zvigadzirwa Zveumbozha uye Dhizaini Inoshanda
Kupfuura kushanda kwakachena, matombo eruby dzimwe nguva anosanganiswa mumapeni emhando yepamusoro, makampasi, zvishongo, uye magirazi ekuona—zvinoshanda sezvinhu zvekuvaka uye zvekushongedza. Ruvara rwawo rutsvuku rwakadzama uye nzvimbo dzakakwenenzverwa zvinobatsira ku:
-
Kunatswa kwerunako
-
Kumiririrwa kwekufananidzira kwekunyatsojeka uye kugara kwenguva refu
-
Kuwedzera kukosha kwechigadzirwa mumisika yepamusoro-soro
