Lub nano-laser yog hais txog cov khoom siv micro-cov ntaub so ntswg xws li nanowires xws li nanowires ua cov kab noj hniav resonant, uas tuaj yeem tawm lub teeb laser hauv qab lub teeb lossis hluav taws xob zoo siab.
Nrog rau txoj kev loj hlob ntawm nanotechnology thiab nano photon, lub compact miniaturized laser daim ntawv thov prospects muaj kev txhawj xeeb. Thaum lub laser resonance kab noj hniav loj yog txo mus rau lub emission wavelength, ib tug nthuav lub cev nyhuv yuav generated nyob rau hauv lub electromagnetic resonant kab noj hniav. Yog li ntawd, nyob rau hauv lub ultra-ceev coherent lub teeb qhov kev loj hlob ntawm tsawg-dimensional, tsis tshua muaj twj tso kua mis pib, thiab thaum lub nano-optoelectronic kev koom ua ke thiab plasma optical txoj kev yog tsim, peb-dimensional loj ntawm lub semiconductor laser yog ib qho tseem ceeb.
Nrog rau kev nce qib ntawm tib neeg kev tshawb fawb thiab thev naus laus zis, kev txhim kho ntawm laser nws tus kheej tsis tau nres. "Science" luam tawm Berkeley, California University, USA. Huang, P. Y., et al. "Nano-laser" ntawm Chav Kub Kub Ultraviolet Radiation" lees tias yog lub ntiaj teb lub laser me tshaj plaws. Thaum lub sijhawm ntawd, lawv thawj plated 1 txog 3.5 microns tuab kub ntawm sapphire substrate, thiab tom qab ntawd muab lawv tso rau hauv ib lub tais evaporating ntawm txhuas, ua kom sov. cov khoom thiab substrate rau hauv 880 mus rau 905 degrees Celsius nyob rau hauv argon los tsim Zn chav, tsim Zn vapor yog kis mus rau lub substrate, li 2 mus rau 10 feeb, thiab tus ntoo khaub lig seem yog ib tug hexagonal nanowire loj hlob mus rau 2 mus rau 10 microns.
Kev tshawb fawb nano laser yog ib qho tseem ceeb rau kev tshawb fawb yooj yim thiab siv tau. Ua ntej, cov khoom siv ob sab yog cov khoom siv kho qhov muag thinnest, uas tau raug pov thawj los txhawb kev ua haujlwm laser ntawm qhov kub thiab txias, tab sis seb cov khoom siv ib txheej molecular puas txaus los txhawb kev ua haujlwm laser ntawm chav tsev kub, nyob rau hauv thaj tsam kev tshawb fawb thiab thev naus laus zis. . Chav ntsuas kub yog qhov tsim nyog ntawm feem ntau ntawm cov ntawv siv laser tiag tiag, yog li chav ntsuas kub ntawm lub laser tshiab yog ntsuas hauv keeb kwm ntawm semiconductor laser kev loj hlob. Tsis tas li ntawd, vim muaj zog Kurun kev sib cuam tshuam nyob rau hauv ob-dimensional khoom, electrons thiab qhov ib txwm tshwm sim nyob rau hauv exciton xeev, yog li no laser tiag tiag muaj ib tug tshiab hom exciton polarized lub cev muaj zog-Einstein Cohesion yog ze ze, uas yog ib qho ntawm feem ntau. cov ntsiab lus nquag hauv kev ua haujlwm ntawm physics yooj yim.
Lub nano-laser tsuas yog hais txog 100 micro-mais tam sim no. Cov kws tshawb fawb hauv nano-lasers tau txo cov xov hlau photon mus rau tsuas yog ib feem tsib cubic micron ntim. Ntawm qhov ntsuas no, tus naj npawb ntawm photon xeev ntawm cov qauv no tsawg dua 10, ze rau cov xwm txheej uas yuav tsum tau ua haujlwm yam tsis muaj zog, tab sis tus naj npawb ntawm photons tsis tau txo qis rau cov kev txwv.
Tsis ntev los no, cov kws tshawb fawb ntawm MIT Academy yuav raug xa mus rau hauv lub laser ib los ntawm ib qho ntawm cov bismuth atoms zoo siab. Txhua lub atom emissions ib qho txiaj ntsig photon ntxiv rau qhov ua tau zoo, thiab kev ua haujlwm ntawm qhov tsis siv hluav taws xob nanomae tuaj yeem ua rau nrawm. Laser ceev. Txij li thaum tsuas yog lub zog me me yuav tsum tau, lub laser tuaj yeem kis tau, cov khoom siv no tuaj yeem paub cov keyboards tam sim ntawd. Qee lub lasers tau ua kom haum rau kev sib txuas lus fiber ntau ntawm kev hloov pauv sai dua 20 billion ib ob. Vim muaj kev loj hlob sai ntawm nanotechnology, qhov kev siv ntawm no invaluable pib nano-laser yuav raug xa mus rau.
Nano lasers tau dav siv hauv kev suav lub teeb, cov ntaub ntawv khaws cia thiab nanometrics. Nanosus lasers tuaj yeem siv rau circuitry, uas tuaj yeem tswj tau qhov hloov pauv. Yog hais tias lub laser integrates lub installation mus rau lub nti, lub computer disk cov ntaub ntawv cia tus nqi thiab cov ntaub ntawv cia tus nqi ntawm lub computer photon yav tom ntej yog zoo dua, thiab kev koom ua ke kev loj hlob ntawm cov ntaub ntawv technology yog ceev.
