Kuyesera kwa LPT-11 pa Semiconductor Laser

Kufotokozera

Laser nthawi zambiri imakhala ndi magawo atatu
(1) Chogwirira ntchito cha laser
Kupanga laser kuyenera kusankha njira yoyenera yogwirira ntchito, yomwe ingakhale gasi, madzi, olimba kapena semiconductor. Mu mtundu uwu wa njira, kusintha kwa chiwerengero cha tinthu tating'onoting'ono kumatha kuchitika, komwe ndikofunikira kuti laser ipezeke. Mwachiwonekere, kukhalapo kwa mphamvu yokhazikika kumapindulitsa kwambiri pakuzindikira kusintha kwa chiwerengero. Pakadali pano, pali mitundu pafupifupi 1000 ya zolumikizira zogwirira ntchito, zomwe zimatha kupanga mafunde osiyanasiyana a laser kuyambira VUV mpaka infrared yakutali.
(2) Gwero la chilimbikitso
Kuti kusintha kwa chiwerengero cha tinthu tating'onoting'ono kuwonekere mu malo ogwirira ntchito, ndikofunikira kugwiritsa ntchito njira zina zolimbikitsira dongosolo la atomiki kuti muwonjezere chiwerengero cha tinthu tating'onoting'ono mu gawo lapamwamba. Kawirikawiri, kutulutsa mpweya kungagwiritsidwe ntchito kusonkhezera maatomu a dielectric ndi ma electron okhala ndi mphamvu ya kinetic, yomwe imatchedwa kusonkhezera magetsi; gwero la kuwala kwa pulse lingagwiritsidwenso ntchito kuwunikira malo ogwirira ntchito, omwe amatchedwa kusonkhezera kuwala; kusonkhezera kutentha, kusonkhezera mankhwala, ndi zina zotero. Njira zosiyanasiyana zolimbikitsira zimawonedwa ngati pampu kapena pampu. Kuti mupeze kutulutsa kwa laser mosalekeza, ndikofunikira kupompa mosalekeza kuti chiwerengero cha tinthu tating'onoting'ono mu gawo lapamwamba chikhale chochulukirapo kuposa chomwe chili mu gawo lotsika.
(3) M'mimba mwa Resonant
Ndi zinthu zoyenera zogwirira ntchito komanso gwero lolimbikitsa, kusintha kwa tinthu tating'onoting'ono kumatha kuchitika, koma mphamvu ya kuwala kolimbikitsidwa ndi yofooka kwambiri, kotero singagwiritsidwe ntchito pochita. Chifukwa chake anthu amaganiza zogwiritsa ntchito resonator yowunikira kuti iwonjezere mphamvu. Chomwe chimatchedwa resonator yowunikira kwenikweni ndi magalasi awiri okhala ndi kuwala kwakukulu komwe kumayikidwa moyang'anizana mbali zonse ziwiri za laser. Chimodzi chimakhala pafupifupi chiwonetsero chonse, china chimawonetsedwa kwambiri ndipo chimatumizidwa pang'ono, kotero kuti laser ikhoza kutulutsidwa kudzera pagalasi. Kuwala komwe kumawonetsedwa kubwerera ku malo ogwirira ntchito kumapitiliza kuyambitsa kuwala kwatsopano kolimbikitsidwa, ndipo kuwala kumakulitsidwa. Chifukwa chake, kuwalako kumasinthasintha mmbuyo ndi mtsogolo mu resonator, zomwe zimapangitsa kuti pakhale kusintha kwa unyolo, komwe kumakulitsidwa ngati chipale chofewa, ndikupanga kutulutsa kwamphamvu kwa laser kuchokera kumapeto kwa galasi lowonetsera pang'ono.
