Zoyeserera za LPT-11 seri pa Semiconductor Laser

Kufotokozera

Laser nthawi zambiri imakhala ndi magawo atatu
(1) Laser ntchito sing'anga
M'badwo wa laser uyenera kusankha njira yoyenera yogwirira ntchito, yomwe imatha kukhala gasi, madzi, olimba kapena semiconductor.Mu mtundu uwu wa sing'anga, kutembenuka kwa chiwerengero cha tinthu tating'onoting'ono kumatha kuzindikirika, chomwe ndi chofunikira kuti mupeze laser.Mwachiwonekere, kukhalapo kwa msinkhu wa mphamvu ya metastable ndikopindulitsa kwambiri pakuzindikiritsa chiwerengero cha inversion.Pakalipano, pali mitundu pafupifupi 1000 ya ma TV omwe amagwira ntchito, omwe amatha kupanga mafunde osiyanasiyana a laser kuchokera ku VUV kupita ku infrared.
(2) Gwero lachilimbikitso
Pofuna kuti kutembenuka kwa chiwerengero cha particles kuwonekere mu sing'anga yogwira ntchito, m'pofunika kugwiritsa ntchito njira zina kuti musangalatse dongosolo la atomiki kuti muwonjezere chiwerengero cha particles kumtunda.Kawirikawiri, kutulutsa mpweya kungagwiritsidwe ntchito kusangalatsa ma atomu a dielectric ndi ma elekitironi omwe ali ndi mphamvu ya kinetic, yomwe imatchedwa kutulutsa magetsi;gwero la kuwala kwa pulse lingagwiritsidwenso ntchito kuti irradiate sing'anga yogwira ntchito, yomwe imatchedwa optical excitation;kutengeka kwa matenthedwe, kutengeka kwa mankhwala, ndi zina zotero. Njira zosiyanasiyana zokokera zimawonetsedwa ngati mpope kapena mpope.Kuti tipeze laser linanena bungwe mosalekeza, m'pofunika kupopera mosalekeza kusunga chiwerengero cha particles kumtunda mlingo kuposa m'munsi.
(3) Mphuno yomveka
Ndi zinthu zoyenera zogwirira ntchito ndi gwero lachisangalalo, kutembenuka kwa tinthu tating'onoting'ono kumatha kuzindikirika, koma mphamvu ya cheza yolimbikitsidwa ndi yofooka kwambiri, kotero siyingagwiritsidwe ntchito.Chifukwa chake anthu amaganiza zogwiritsa ntchito optical resonator kuti akulitse.Otchedwa kuwala resonator kwenikweni magalasi awiri ndi mkulu reflectivity anaika maso ndi maso pa malekezero onse a laser.Chimodzi chimakhala pafupifupi chiwonetsero chonse, chinacho chimawonetsedwa kwambiri ndikufalikira pang'ono, kotero kuti laser ikhoza kutulutsidwa kudzera pagalasi.Kuwala komwe kumabwereranso kumalo ogwirira ntchito kumapitirizabe kutulutsa ma radiation atsopano, ndipo kuwala kumakulitsidwa.Chifukwa chake, kuwala kumazungulira mmbuyo ndi mtsogolo mu resonator, kuchititsa kuti unyolo uchitike, womwe umakulitsidwa ngati chigumukire, kutulutsa kutulutsa kwamphamvu kwa laser kuchokera kumalekezero amodzi a galasi lowonetsera pang'ono.
