Kuwongolera Kutentha Kwambiri kwa Laser Systems ndi Industrial Applications Kuyambira 2002
Chilankhulo
Kuwala kwa laser kumapambana mu monochromaticity, kuwala, mayendedwe, ndi kugwirizana, kumapangitsa kukhala koyenera kugwiritsa ntchito molondola. Wopangidwa ndi mpweya wosonkhezera ndi kukulitsa kwa kuwala, mphamvu zake zotulutsa mphamvu zambiri zimafuna zozizira zamadzi m'mafakitale kuti zigwire ntchito mokhazikika komanso moyo wautali.
Ukadaulo wa laser wasintha mafakitale osiyanasiyana, kuyambira opanga mpaka azachipatala. Koma nchiyani chimapangitsa kuwala kwa laser kukhala kosiyana ndi kuwala wamba? Nkhaniyi ikuwonetsa kusiyanitsa kwakukulu komanso njira yoyambira yopanga laser.
Kusiyana Pakati pa Laser ndi Kuwala Wamba
1. Monochromaticity: Kuwala kwa laser kumakhala ndi mawonekedwe abwino kwambiri, kutanthauza kuti kumakhala ndi utali wotalikirapo umodzi wokhala ndi mzere wocheperako kwambiri. Mosiyana ndi zimenezi, kuwala wamba kumakhala kosakanikirana ndi mafunde angapo, zomwe zimapangitsa kuti pakhale mawonekedwe otambalala.
2. Kuwala ndi Kachulukidwe ka Mphamvu: Miyendo ya laser imakhala ndi kuwala kwakukulu komanso kusasunthika kwa mphamvu, zomwe zimawalola kuyika mphamvu zamphamvu mkati mwa malo ang'onoang'ono. Kuwala wamba, ngakhale kumawoneka, kumakhala ndi kuwala kochepa kwambiri komanso kuyika mphamvu. Chifukwa cha mphamvu zambiri zotulutsa ma lasers, njira zoziziritsa zogwira mtima, monga zoziziritsa kukhosi zamafakitale, ndizofunikira kuti zisunge magwiridwe antchito komanso kupewa kutenthedwa.
3. Directionality: Miyendo ya laser imatha kufalikira m'njira yofananira kwambiri, kukhala ndi mbali yaying'ono yosiyana. Izi zimapangitsa ma lasers kukhala abwino kwa ntchito zolondola. Kuwala wamba, kumbali ina, kumawonekera mbali zingapo, zomwe zimatsogolera kubalalitsidwa kwakukulu.
4. Kugwirizana: Kuwala kwa laser kumakhala kogwirizana kwambiri, kutanthauza kuti mafunde ake ali ndi maulendo ofanana, gawo, ndi njira yofalitsa. Kugwirizana kumeneku kumathandizira ntchito monga holography ndi kulumikizana kwa fiber optic. Kuwala wamba kulibe kugwirizanitsa kumeneku, ndipo mafunde ake amawonetsa magawo ndi mayendedwe.
Momwe Kuwala kwa Laser kumapangidwira
Njira yopangira laser imatengera mfundo yolimbikitsa kutulutsa. Zimakhudza njira zotsatirazi:
1. Kutulutsa Mphamvu: Ma atomu kapena mamolekyu mu laser medium (monga gasi, olimba, kapena semiconductor) amatenga mphamvu zakunja, kusintha ma electron kupita ku mphamvu yapamwamba.
2. Population Inversion: Mkhalidwe umatheka pamene tinthu tambiri timakhala mu chikhalidwe chosangalatsa kusiyana ndi mphamvu zochepa, zomwe zimapangitsa kuti chiwerengero cha anthu chiwonjezeke - chofunika kwambiri pakuchita laser.
3. Kutulutsa Kokoka: Pamene atomu yokondwa ikumana ndi chithunzithunzi chomwe chikubwera cha utali winawake wa kutalika kwake, imatulutsa chithunzi chofanana, kukulitsa kuwala.
4. Optical Resonance ndi Amplification: Ma photon opangidwa amawonekera mkati mwa optical resonator (magalasi awiri), akukulitsa mosalekeza pamene ma photon ambiri amalimbikitsidwa.
5. Kutulutsa kwa Laser Beam: Mphamvu ikafika pachimake chovuta, mtengo wolumikizana, wolunjika kwambiri umatulutsidwa kudzera pagalasi lowoneka pang'ono, lokonzekera kugwiritsidwa ntchito. Monga ma lasers amagwira ntchito pa kutentha kwakukulu, kuphatikiza chozizira cha mafakitale kumathandizira kuwongolera kutentha, kuwonetsetsa kuti laser imagwira ntchito komanso kukulitsa moyo wa zida.
Pomaliza, kuwala kwa laser kumasiyanitsidwa ndi kuwala wamba chifukwa cha mawonekedwe ake apadera: monochromaticity, kachulukidwe kamphamvu kwambiri, kuwongolera bwino, komanso kulumikizana. Njira yeniyeni yopangira laser imathandizira kuti igwiritsidwe ntchito kwambiri m'magawo apamwamba kwambiri monga kukonza mafakitale, opaleshoni yachipatala, ndi kulumikizana kwa kuwala. Kuti muwongolere bwino makina a laser komanso moyo wautali, kugwiritsa ntchito chotsitsa madzi odalirika ndi chinthu chofunikira kwambiri pakuwongolera kukhazikika kwamafuta.
Tabwera chifukwa cha inu mukadzatifuna.
Chonde lembani fomu yolumikizana nafe, ndipo tidzakhala okondwa kukuthandizani.

TEYU S&A Chiller idakhazikitsidwa mu 2002 ndi zaka 23 zopanga zoziziritsa kukhosi, ndipo tsopano amadziwika kuti ndi mpainiya waukadaulo wozizira komanso mnzake wodalirika pamakampani a laser.
