Nanolaser erudzi rwe micro uye nano mudziyo uyo wakagadzirwa neNanomatari akadai seNanowire seyekuita seyekuita uye inogona kusimbisa laser pasi pemagetsi kana magetsi emagetsi. Saizi yeiyi laser kazhinji ingori mazana emakroni kana kunyange makumi emiconi, uye dhayamu iri kuNanometer Order, iyo yakakosha yeramangwana rakaonda remuti, rakabatanidzwa arocics uye mamwe minda.
Kuiswa kweNanolaser:
1. Nanowire laser
Muna 2001, vanotsvaga kuUniversity of California, Berkeley, muUnited States, vakagadzira dunhu renyika diki reSerles - Nanoolaser Iyi laser haigoni kungoisa lasers lasers, asi inogona zvakare kuvezwa kuti ibve mitemo kubva kublue kusvika kublue kusvika pakadzika ultraviolet. Vatsvagiri vakashandisa nzira yakajairika inonzi yakagadzirirwa Epiphytation kuti vagadzire laser kubva pakachena zinc oxide makristasi. Ivo kutanga "kwetsika" nanowires, ndiko kuumbwa pamusoro pegoridhe ine dhaya ye20nm kusvika ku150nm uye kureba kwe1000 nm yakachena zinc oxide wires. Zvino, apo vatsvagiri vachimugadzirisa zinc cryital makristasi muNanoawires ine imwe laser pasi pegirini, iyo yeZinc oxide yakaburitsa laser ine mavhesi ezhizha chete 17nm. Nazolasers vakadaro vanozopedzisira vashandiswa kuona makemikari uye kuvandudza ruzivo rwekuchengetedza ruzivo rwekombuta disks uye makomputa emakomputa.
2. Ultraviolet nanolaser
Kutevera kukwikwidza kwemocro-lasers, micro-mick-disk lasers, micro-mhete lasers Iyi zinc oxide nanolaser inogona kuburitsa laser ine mutsara wetsimbe pane isingasviki 0.3nm uye inoonekwa seyakajeka laser munyika uye imwe yemidziyo yekutanga inogadzirwa uchishandisa Nuzotechnology. Mudanho rekutanga rekusimudzira, vatsvagiri vakafanotaura kuti izvi zveZno nanolaser zviri nyore kugadzirwa, kupenya kwakanyanya, saizi diki, uye kuita kwacho kwakaenzana kana kuve nani pane gan lasers lasers. Nekuda kwekugona kuita yakakwira-density nanowire arrays, zno nanolasers inogona kupinda akawanda mashandisirwo ayo asiri midziyo yanhasi. Kuti ikure vakadaro lasers, zno nanowire iri synthesised negero yekutakura gasi iyo inokanganisa Epitaxial Cry Scress kukura. Kutanga, iyo Sapphire Substrate inounganidzwa neye 1 nm ~ 3.5nm goho goridhe firimu, iyo zvinhu uye iyo ° ° C ' Nanowires of 2μm ~ 10μm ine Hexagonal Cross-Chikamu nzvimbo yakagadzirwa mukukura kwekukura kwe 2min ~ 10min. Vaongorori vakawana kuti zno nanowire inoumba mafambiro echisikigo laser neyakajaira 20nm kusvika ku150nm, uye yakawanda (95%) yeyaro dhaya ndeye 70nm kusvika 100nm kusvika 100nm kusvika 100nm. Kuti udzidze stimated emission yeNanowires, vaongorori vanoputika, vaongorori vakapukuta sampuli mune greenhouse neyechina Harmonic kubuda kweA ND: 266nm wavelength Munguva yekushanduka-shanduka kwekubuda kwehusimbe, mwenje wakarara nekuwedzera kwesimba remapomba. Kana kusuwa kunodarika chikumbaridzo che zno nanowire (anenge 40KW / cm), nzvimbo yepamusoro icharatidzika mukubuda kwe emission. Upamhi hwakatetepa hwemapepa epamusoro-soro pane pasi pe 0.3nm, iro rinopfuura 1/50 risingasviki mutsara wehupamhi kubva kuEmissix vertex pazasi chikumbaridzo. Iyi mitsara yakatetepa uye nekukurumidza inowedzera mukubuda mukuwedzera kwakatungamira vaongorori kuti vafunge kusimuka kunoitika zvechokwadi mune idzi muzviitwa nonewires. Naizvozvo, uyu arrayire array anogona kuita seyakagadzika sosi uye nekudaro ikaita yakanaka micro laser sosi. Vanoongorora vanotenda kuti ipfupi-wavelength nanolength nanolaser inogona kushandiswa muminda yeiyo Optical computing, ruzivo rwekuchengetedza uye nanoanalyzer.
3. Quantum zvakanaka lasers
Asati agara uye apedza 2010, mutsara wedzera Kugadzirisa dambudziko iri, Levantum zvakanaka lasers akaberekerwa. Muhuwandu hwem mechanics, munda waigona unonamatira kufambisa kweaine magetsi uye anovhurwa iwo anonzi quantum tsime. Iyi quantum constraint inoshandiswa kuumba huwandu hwehuwandu hwehuwandu hweSecomes yeSecomonductor Laser, kuti shanduko yemagetsi iri pakati peServents Kune marudzi maviri ehuwandu hwehuwandu lasers lasers: Quantum line lasers uye huwandu hwehuwandu.
① Quantum mutsara laser
Masayendisiti akagadzira huwandu hwehuwandu hwehuwandu hwekurarama ane chiuru chimwe chete zvine simba pane zvetsika lasers, kutora nhanho hombe yekugadzira inokurumidza makomputa uye zvishandiso zvekutaurirana. Iyo laser, iyo inogona kuwedzera kumhanya kweutio, vhidhiyo, internet uye mamwe maitiro ekutaurirana Aya maSimba-magetsi lasers aigona kuderedza kukosha kwekudzokorora kwemasikati, ayo anoiswa pamhepo yekutaurirana
