LPT-11 Kafukufuku Woyeserera pa Semiconductor Laser

Kufotokozera

Poyesa mphamvu, mphamvu yamagetsi komanso mphamvu ya semiconductor laser, ophunzirawo amatha kumvetsetsa magwiridwe antchito a semiconductor laser potulutsa mosalekeza. Optical multichannel chowunikira imagwiritsidwa ntchito poyang'ana kutulutsa kwa kuwala kwa semiconductor laser pomwe jekeseni wapano ndi wocheperako malire ndi kusintha kwa mzere wama laser oscillation pomwe pano ndi wamkulu kuposa momwe aliri pano.

Laser ambiri amakhala ndi magawo atatu
(1) Laser ntchito sing'anga
Mbadwo wa laser uyenera kusankha sing'anga yoyenera kugwira ntchito, yomwe ingakhale gasi, madzi, olimba kapena semiconductor. Mwa sing'anga yamtunduwu, kusinthidwa kwa kuchuluka kwa tinthu kumatha kukwaniritsidwa, chomwe ndichofunikira kuti mupeze laser. Zachidziwikire, kupezeka kwamphamvu yamagetsi ndiyopindulitsa kwambiri pakuzindikira kusintha kwa manambala. Pakadali pano pali mitundu pafupifupi 1000 ya media media, yomwe imatha kupanga ma wavelengths osiyanasiyana kuchokera ku VUV mpaka infrared.
(2) Gwero lolimbikitsa
Pofuna kusokoneza kuchuluka kwa tinthu tomwe tikugwira ntchito, ndikofunikira kugwiritsa ntchito njira zina kuti tisangalatse dongosolo la atomiki kuti liwonjezere kuchuluka kwa ma particles kumtunda wapamwamba. Mwambiri, kutulutsa kwa gasi kumatha kugwiritsidwa ntchito kusangalatsa ma atomu a dielectric ndi ma elekitironi okhala ndi mphamvu zamagetsi, zomwe zimatchedwa kukondoweza kwamagetsi; zimachitika kuwala gwero Angagwiritsidwenso ntchito kuunikira sing'anga ntchito, wotchedwa kutentha kukopa; matenthedwe malemeredwe, mankhwala malemeredwe, etc. Njira zosiyanasiyana malemeredwe ndi visualized ngati mpope kapena mpope. Kuti tipeze kutulutsa kwa laser mosalekeza, ndikofunikira kupopera mosalekeza kuti tisunge kuchuluka kwa tinthu tating'onoting'ono kuposa tomwe timakhala m'munsi.
(3) Resonant patsekeke
Ndi magwiridwe antchito oyenera komanso gwero lazokopa, kusokonekera kwa nambala ya tinthu kumatha kuzindikirika, koma mphamvu ya cheza cholimbikitsidwa ndi chofooka kwambiri, chifukwa chake sichingagwiritsidwe ntchito. Chifukwa chake anthu amaganiza zogwiritsa ntchito pokonza mawu kuti akule. Otchedwa optical resonator kwenikweni ndi magalasi awiri okhala ndi mawonekedwe owoneka bwino kumapeto kwa laser. Chimodzi chimanyezimiritsa pafupifupi china, china chimakhala chowonekera komanso chimafalikira pang'ono, kuti laser athe kutulutsa kudzera pagalasi. Kuwalako komwe kumabwereranso kwa sing'anga yomwe ikugwirabe ntchito kumapitilizabe kuyatsa ma radiation, ndipo kuwala kumakulitsa. Chifukwa chake, kuwalako kumangoyenda uku ndi uku mu resonatoryo, ndikupangitsa kuyanjana kwa unyolo, komwe kumakulitsidwa ngati chiwombankhanga, ndikupanga kutulutsa kwamphamvu kwa laser kuchokera kumapeto amodzi a kalilole wowala pang'ono.
