Nanolaser ndi mtundu wa micro ndi Nano yomwe imapangidwa ndi nanomatadium monga nanoowolire ngati masisitere ndipo amatha kutulutsa laser mu proexcation kapena magetsi. Kukula kwa laseryi nthawi zambiri kumangokhala microns kapena ma makumi asanu ndi a Microns, ndipo m'mimba mwake muli dongosolo la nanometer, lomwe ndi gawo lofunikira m'phiri la filimu yopyapyala, kuphatikizapo zopyaptics ndi minda ina.
Gulu la Nanolaser:
1. Nanoow Auser
Mu 2001, ofufuza ku Yunivesite ya California, Berkeley, ku United States, adapanga laser yaying'ono yadziko lapansi - nanoolaser - pa waya wa nanooptic. Malondawa sangopereka ma altraviolet a Ultraviolet Lasers, koma amathanso kukonzedwa kuti atuluke kuchokera ku Blue kupita ku Blue Ultraviolet. Ofufuzawo adagwiritsa ntchito njira yodziwika yotchedwa epiphytation yotchedwa laser kuchokera ku ma kristo a zinc. Amayamba "nanoowi zotchuka" kumangidwa, zomwe zimapangidwa pamwala wagolide ndi ma 15nm mpaka kutalika kwa 10,000 nm zimba zinc zoyera. Kenako, pamene ofufuzawo akamayambitsa makristali a zinc mu nanoowing ndi laser wina mu wowonjezera kutentha, makrisya a zinc oxide omwe amatulutsa laser ya 17nm yokha. Nanolasers oterewa amatha kugwiritsidwa ntchito kuzindikira mankhwala ndikuwongolera kuchuluka kwa zidziwitso zamakompyuta ndi makompyuta.
2. Ultraviolet nanolaser
Kutsatira kuchitika kwa micro-atch, mapiri a micro-mphete, ma Lasers a Micro-mphete, ndi a centram avanche peidong ndi ogwira nawo ntchito ku Yunivesite ya California, Berkeley, adapanga kutentha kwa Nanolaser. Izi zinc oxide nanolaser imatha kutulutsa laser yocheperako 0,3nm ndi mawonekedwe a 385nm pansi pa chidule cha dziko lapansi ndipo imodzi mwazida zazing'ono zomwe zimapangidwa mdziko lapansi. Mu gawo loyamba lachitukuko, ofufuzawo adaneneratu kuti Zno nanolaser iyi ndikosavuta kupanga, kuwunika kwakukulu, kukula kochepa, ndipo magwiridwe antchito ndi ofanana ndi anyani a buluu. Chifukwa chotha kupanga ma nayowa-basnsire arrays, Zno nanolaser amatha kulowetsa ntchito zambiri zomwe sizingatheke ndi zida zamakono. Pofuna kukula ma laser otere, Zno nanoowere amapangidwa ndi njira yoyendera yamagesi yomwe imakulira chozungulira epitaxial. Choyamba, chopindika cha sapjere chimakhala ndi chosanjikiza cha 1 nm ~ 3.5nm filimu yamphamvu ya alumu steam kuti apange zikondwerero za Ammonia. Nanoolires wa 2μm ~ 10μm ndi hexagonal pamtandapo adapangidwa pakukula kwa 2min ~ 10min. Ofufuzawo adapeza kuti Zno Nnowolot amapanga chibadwa chambiri cha ma 20nm mpaka 150nm, ndipo ambiri (95%) ndi 1000nm. Kuti muphunzire zolimbikitsa za nanowit, ofufuzawo adapukutira bwino mwachitsanzo Pakusintha kwa chilengedwe, Kuwala kumangidwa ndi kuwonjezeka kwa mphamvu yopopera. Pamene khosi limapitilira pakhomo la Zno nanoowolire (pafupifupi 40kW / cm), malo apamwamba kwambiri adzaonekera muzolowera. Mzerewu mulifupi wa mfundo zazikuluzikulu kwambiri ndi zosakwana 0.3nm, yomwe ili yoposa 1/50 yoposa 1/50 kuposa mzere mtunda kuchokera pamutu womwe uli pansipa. Kukula kopapatiza komanso kuwonjezeka mwachangu pakutsogolera ofufuzawo kuti anene kuti kukhumudwitsidwa kumachitikanso. Chifukwa chake, gululi la nanoowolire limatha kukhala ngati wachilengedwe ndipo motero imakhala gwero labwino la serse. Ofufuzawo amakhulupirira kuti kusefukira kwamphamvu kwambiri kumeneku kungagwiritsidwe ntchito m'minda ya mapangidwe am'matumba, osungirako chidziwitso ndi nanoanalyhe.
3. Quantum bwino
Asanachitike ndi pambuyo pa chaka cha 2010, mzere wam'taliwo unafika pa 100nm kapena kuchepera, ndipo kupezeka ma elekitoni ochepa oyendayenda Kuti muthane ndi vutoli, runum chabwino a Lasers adabadwa. Mu simenti Machisi, munda womwe umalepheretsa kuyenda kwa ma elekitironi ndikuwapeza amatchedwa kuchuluka. Chipwirikitichi chimagwiritsidwa ntchito kuti apange milingo yamphamvu yamphamvu mu semiconductor ya semiconduct, kotero kuti kusintha kwa magetsi pakati pa magetsi kumayambitsa laser, yomwe ndi yasemenum yabwino. Pali mitundu iwiri ya ma Lasers apamwamba: kuchuluka kwa ma Lasers ndi madontho a dout.
① kuchuluka kwa chingwe
Asayansi apanga ma aya a aya omwe ndi amphamvu zoposa 1,000 zoposa ma lasers achikhalidwe, akutenga gawo lalikulu pakupanga makompyuta mwachangu komanso zida zolankhulirana. Laser, yomwe imatha kuwonjezera liwiro la audio, kanema, intaneti ndi mitundu ina yolumikizirana ndi asayansi, yomwe idapangidwa ndi asing'anga ya max ku Dresden, Germany. Ma lasers apamwamba kwambiri amachepetsa kufunika kwa obwereza opukutira, omwe amakhazikitsidwa chilichonse (500km (makilomita 50) m'njira yolumikizirana, inanso ya laser yomwe imakhala yolimba kwambiri pamene akuyenda pansi.
