Lembetsani ku media yathu yothandizira potumiza
Lasers, mwala wapangodya wamakono wamakono, ndiwosangalatsa monga ndizovuta. Pamtima pawo ngakhale nyimbo zikuluzikulu zomwe zimagwira ntchito mogwirizana kuyenera kupanga zogwirizana, kuwala. Mabulosi awa akukhudzana ndi zigawo za zinthuzi, zomwe zimathandizidwa ndi mfundo za sayansi komanso zifaniziro, kuti mumvetsetse bwino ukadaulo wa laser.
Kuzindikira Kwapamwamba Kwambiri
| Chipangizo | Kugwira nchito | Zitsanzo |
| Pezani pakati | Kupeza kwa sing'anga ndi zomwe zili mu laser zogwiritsidwa ntchito pokweza. Imathandizira kuunika kuwunikira kudzera munthawi ya anthu osokoneza bongo komanso kukhumudwitsidwa. Kusankha kwa phindu kumapangitsa kuti pakhale ma radiation a laser. | Lasers olimba: mwachitsanzo, ND: Yag (Newdymium-doptium Yttrium Aluminium adyen), amagwiritsidwa ntchito mu zamankhwala ndi mafakitale.Ma lasers a gasi: mwachitsanzo, a CO2 a Ce2, omwe amagwiritsidwa ntchito podula ndi kuwotcherera.Semiconductor Lasers:Eg, ma diocs a laser, ogwiritsa ntchito chiwonetsero chazomwe kulumikizana ndi ma laser osemphana. |
| Kuponda | Kupanga kapapi kumapereka mphamvu kuti apeze mphamvu kuti apindule ndi kuchuluka kwa anthu (mphamvu yamagetsi kuti anthu atherepo), pomuthandiza kugwirira ntchito. | Kupopera kwamaso: Kugwiritsa ntchito magwero akuluakulu ngati mafayilo oti apukuke-boma.Kupukuta wamagetsi: Kusangalatsa mpweya m'malonda a gasi kudutsa magetsi.Kupompa wa semiconduct: Kugwiritsa ntchito malo osungirako a laser kuti apapidwe osemphana-rock. |
| Mawonekedwe owoneka bwino | Patseke lamiyala, yopangidwa ndi magalasi awiri, imawonetsa kuwala kuti muwonjezere kutalika kwa kuwala mu sing'anga, kenako ndikuwonjezera kuunika. Imapereka njira yofunsira la laser akurre Ampremation, ndikusankha mawonekedwe a Speratral ndi Shipe of the Kuwala. | Makonzedwe okonzekera: Kugwiritsidwa ntchito pofufuza labotale, kusavuta.Blash-Conweve Pachtsenjika: Odziwika mu ma afarsrial a mafakitale, amapereka matabwa apamwamba. Mphepete: Kugwiritsidwa ntchito m'makampani ena a mphete, monga ma lasers a mphete. |
Zovuta: Nexus of the Quantum ndi Exeric Engineering
Mphamvu za kuchulukana
Sing'anga ndi komwe njira yofunika kwambiri yopepuka yopepuka imachitika, chodabwitsa kwambiri chozika mizu ya Quantum. Kulumikizana pakati pa mphamvu ndi tinthu tating'onoting'ono kumayendetsedwa ndi mfundo za kuchonderezedwa kwa anthu. Chiyanjano Chosavuta Pakati pa Kuwala (I), kulimba koyambirira (i0), kusinthika kwa gawo lamphamvu (σ21), ndi ziwerengero zomwe zimafotokozedwa ndi equation i = i0e ^ (N2-N1) L). Kukwaniritsa Kuthetsa Chikumbutso cha anthu, komwe n2> n1, ndikofunikira kuti muwonjezere ndipo ndi mwala wapamtundu wa laser1].
Makina atatu a vs.
M'mapanga a laser, mapulogalamu atatu ndi anayi amagwiritsa ntchito mafayilo ambiri. Makina Atatu, pomwe yosavuta, amafunikira mphamvu zambiri kuti akwaniritse kuchuluka kwa anthu ngati gawo la laseji ndi nthaka. Njira zogwirira ntchito zinayi, kuperekera njira yokwanira kwa anthu ambiri chifukwa chosagwedezeka chifukwa cha kuchuluka kwamphamvu kuchokera ku mphamvu yayikulu, kuwapangitsa kukhala ofala kwambiri pamapulogalamu amakono a Laser [2].
Is Galasi lopakaKodi sing'anga?
Inde, galasi la Erbium-doptium ndi mtundu wa kukonzekera kugwiritsidwa ntchito mu ma laser. Munthawiyi, "Kutulutsa" kumatanthauza njira yowonjezera kuchuluka kwa erbium (er³⁺) kwagalasi. Erbium ndi chinthu chosowa kwambiri padziko lapansi chomwe, chiziphatikizidwa mu gulu lagalasi, likhoza kukula bwino kuwala kudzera chosonkhetsedwa, chofunikira kwambiri pakugawidwa kwa laser.
Galasi ya Erbium-doped imakhala yodziwika bwino pakugwiritsa ntchito malalanje a lasers ndi mikono ya Ampritsieers, makamaka popanga mafayilo apakompyuta. Ndizofunikira kwambiri pamapulogalamuwa chifukwa zimayatsa bwino pozungulira pa 1550 nm, yomwe ndi yofunika kwambiri ya kuwonongeka kwa fiber yotsika mu ulusi wa SICA.
AErbiumma ion omwe amamwa kupukusa (nthawi zambiri kuchokera kwa alaser diide) Ndipo amasangalala ndi mayiko apamwamba. Akabwereranso ku mphamvu zotsika, amatulutsa mahotelo pamalo aveleng, amathandizira pa laser. Izi zimapangitsa galasi loyera la Erbium kukhala logwira ntchito komanso logwiritsira ntchito kwambiri lomwe limapeza munthawi yosiyanasiyana ya laser ndi mapangidwe apamwamba.

Kuthetsana njira kuti mukwaniritse kuwononga anthu
Kusankha kwamakina ampingwi ndi pivotal ku mapangidwe a laser, kukopa chilichonse kuchokera kunjira yokwanira kutulutsa. Kupopera kwamaso, kugwiritsa ntchito magwero akunja monga malalanje kapena malalanje ena, ndizofala m'miyendo yolimba ndi utoto. Njira zamagetsi zamagetsi nthawi zambiri zimagwiritsidwa ntchito m'malonda a gasi, pomwe Semicoctor Lasers nthawi zambiri imagwiritsa ntchito jakisoni ya Elkin. Mphamvu ya njira izi, makamaka mu Lasers Okhazikika-Staters, zakhala gawo lofunikira kwambiri, ndikupanga bwino kwambiri komanso kugwiritsa ntchito bwino [3].
Malingaliro aukadaulo pakupopera mphamvu
Mphamvu ya Kupopera ndi gawo lofunikira kwambiri la mapangidwe a laser, zomwe zimakhudzanso magwiridwe antchito komanso kugwiritsa ntchito ntchito. M'malo olimba, kusankha pakati pa mafakitale ndi ma aser a laser monga gwero la pompo limatha kukhudza momwe dongosololi limagwiritsira ntchito dongosolo, ndipo katundu wambiri. Kukula kwa ma dioki apamwamba, ma diodis okwera a Laser a DPS atembenukira machitidwe a DPS, zomwe zimakuthandizani kwambiri komanso zogwirizira4].
Patseke lamatumba: Engineering Laser
Kapangidwe kake: kuwongolera kayendedwe ka sayansi ndi injini
Patseke lamatumbo, kapena woyambitsa, sikuti ndi chinthu chongopeka koma wotenga nawo mbali yopanga mtengo wa laser. Mapangidwe a patsekeke, kuphatikizapo kupindika kwa magalasi ndi kuphatikizika kwa magalasi, kumathandizira kuti mudziwe zokhazikika, kapangidwe kake, komanso kutulutsa kwa laser. Patsekelo ziyenera kupangidwa kuti zithetsetsetse mawonedwe pomwe mukuchepetsa kutayika, zovuta zomwe zimaphatikizana ndi ukadaulo wamagetsi5.
Oscillation mitu ndi njira yosankha
Kwa Laser Oscillation kuti achitike, phindu lomwe limaperekedwa ndi sing'anga iyenera kupitirira zotayika mkati mwa khola. Vutoli, lomwe limaphatikizidwa ndi chofunikira cholumikizirana cholumikizira, chimalamulira kuti mitundu ingapo yaitali imathandizidwa. Njira yoyeserera ndi mawonekedwe a modell imayendetsedwa ndi kutalika kwakuthupi kwabwino kwambiri6].
Mapeto
Mapangidwe ndi ntchito ya laser imazungulira mawonekedwe owoneka bwino a sayansi ya sayansi ndi luso. Kuchokera pamakina a quameum yolamulira kuti ikhale yovuta kuyika upangiri wa m'maso, gawo lililonse la pulogalamu ya laser limagwira ntchito yofunika kwambiri. Nkhaniyi yanenanso za ukadaulo wovuta wa laser, kupereka chidziwitso chomwe chimapangitsa kumvetsetsa kwapamwamba kwa akatswiri ndi mainjiniya omwe ali m'munda.
