Kodi malo osewerera ndi chiani

Lingaliro la a Lasers omwe amagwiritsa ntchito kutentha pang'ono silatsopano: Laser yachiwiri m'mbiri yake inali yomkhwima. Poyamba, lingaliro limakhala lovuta kugwiritsa ntchito kutentha kwa chipinda, komanso chidwi cha ntchito yotsika-kutentha kwambiri idayamba mu 1990s ndi chitukuko cha ma lasers okwera kwambiri komanso a nthawi.

Mu mphamvu yayikulumagwero a laser, zotsatira za mafuta monga kuwonongeka kwa kutayika, ma lens oterera kapena a laser okhazikika kumatha kukhudza magwiridwe antchito agwero loyera. Kudzera kutentha kochepa, zotsatira zambiri zovulaza zimatha kuphedwa bwino, kuti, sing'anga amafunika kukhazikika ku 77k kapena 4k. Zotsatira zozizira zimaphatikizapo:

Khalidwe lokhala ndi mwayi wopeza bwino limaletsa kwambiri, makamaka chifukwa njira yopanda chingwe imachuluka. Zotsatira zake, kutentha gradiet kumangogwedezeka kwambiri. Mwachitsanzo, matenthedwe akatsitsidwa kuchokera pa 300k mpaka 77k, kutentha kwa matenthedwe a koloko akuwonjezeka ndi chinthu cha asanu ndi awiri.

Kuphatikizika kwamafuta kumachepanso kumatsika kwambiri. Izi, pamodzi ndikuchepetsa kutentha kwabwino, kumabweretsa mphamvu zochepetsera mafuta ndipo chifukwa chake mwayi wochepetsera chotupa.

Kukongoletsa kwa thermo-koyenera kumachepetsedwa, kutsatsa ma lens oterera.

Kuchulukitsa kwa mayamwidwe osokoneza bongo a ion padziko lapansi makamaka chifukwa chochepa kwambiri chifukwa cha kuchuluka kwa mafuta. Chifukwa chake, mphamvu yakufalikira imachepetsedwa ndipo phindu la laser lichuluka. Chifukwa chake, mphamvu yampufumpo ili yochepetsedwa, ndipo mazira ofupikira amatha kupezeka pomwe kusintha kwa Q ikugwira ntchito. Mwa kuwonjezera kupatuka kwa wofalitsayo, malo otsetsereka amatha kusintha, kotero ma parasitic carwor kutayika kumakhala kofunika kwenikweni.

Chiwerengero cha tinthu tating'onoting'ono tambiri ta quasi-Level chimapeza sing'anga chimachepetsedwa, kotero mphamvu yopondapoyo imachepetsedwa ndipo mphamvu yamagetsi imatha. Mwachitsanzo, YB: Yag, yomwe imatulutsa kuwunika ku 1030nm, imatha kuwoneka ngati dongosolo la magawo atatu a Quisi firiji, koma dongosolo la magawo anayi ku 77k. ER: Zomwezo ndizowona kwa yog.

Kutengera ndi kupezeka kwapakati, kukula kwa njira zina zopukutira kumachepa.

Kuphatikizidwa ndi zinthu zomwe zili pamwambapa, ntchito yotsika kutentha imatha kusintha magwiridwe antchito. Makamaka, kutentha pang'ono kuzizira kumatha kutulutsa mphamvu yokwezeka popanda mphamvu, ndiye kuti, mtengo wabwino umatha kupezeka.

Magazini imodzi yolingana ndi yomwe ili mumtundu wa lasertal, bandwidth ya kuwala kowala ndi kuwala kopepuka kudzachepa, motero kuchuluka kwa funde kudzakhala kocheperako, ndipo mzere wam'ng'ono umakhala wokhazikika wa laseji. Komabe, izi nthawi zambiri zimakhala zosowa.

Kuzizira kwa crykogenic nthawi zambiri kumagwiritsa ntchito chozizira, monga madzi nayitrogeni kapena madzi a helirium, komanso firiji ya firiji yozungulira mu chubu ophatikizidwa ndi phulu la laser. Coolant imabwezeredwanso mu nthawi kapena yobwezeretsedwanso mu loop yotsekedwa. Pofuna kupewa kukhazikika, nthawi zambiri pamafunika kuyika laser a laser m'chipinda chopumira.

Lingaliro la masiketi a laser amagwira ntchito motentha amathanso kugwiritsa ntchito kwa amplifeli. Sakachium imatha kugwiritsidwa ntchito popanga njira yabwino yothandizira, mphamvu yayikulu yotulutsa mu ma wtts.

Ngakhale zida zozizira zozizira zimatha kusokonezaNjira Zosefera, makina ozizira ochulukirapo nthawi zambiri amakhala osavuta, ndipo luso la kuzizira kwa crybogenic limalola kuchepetsa ena.
