Cov txiv hmab txiv ntoo ntawm kev tshawb fawb thiab thev naus laus zis tsis yog ib txwm pom lawv cov tswv yim qhia tawm tam sim tom qab kev npaj ntawm lub hauv paus theoretical. Qhov no tshwm sim nrog laser thev naus laus zis, qhov muaj peev xwm ntawm qhov tsis tau nthuav tawm kom deb li deb. Txoj kev xav ntawm optical quantum generators, raws li lub tswv yim ntawm cov khoom siv hluav taws xob hluav taws xob hluav taws xob tsim hluav taws xob tau tsim, yog ib feem ntawm kev ua kom zoo ntawm laser technology. Txawm li cas los xij, cov kws tshaj lij tau sau tseg tias lub peev xwm ntawm cov hluav taws xob kho qhov muag tuaj yeem ua lub hauv paus rau ntau qhov kev tshawb pom yav tom ntej.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub cuab yeej
Nyob rau hauv rooj plaub no, lub tshuab hluav taws xob quantum tau nkag siab tias yog lub tshuab hluav taws xob laser ua haujlwm hauv qhov kho qhov muag nyob rau hauv cov xwm txheej ntawm kev txhawb nqa monochromatic, electromagnetic lossis coherent hluav taws xob. Lub hauv paus chiv keeb ntawm lo lus laser hauv kev txhais lus qhia txog cov nyhuv ntawm lub teeb amplification.los ntawm stimulated emission. Txog rau tam sim no, muaj ntau lub tswv yim rau kev siv lub tshuab laser, uas yog vim qhov tsis meej ntawm cov hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob optical quantum hauv cov xwm txheej sib txawv.
Qhov sib txawv tseem ceeb yog lub hauv paus ntsiab lus ntawm kev sib cuam tshuam ntawm laser hluav taws xob nrog lub hom phiaj cov khoom. Nyob rau hauv cov txheej txheem ntawm hluav taws xob, lub zog tau muab rau hauv qee qhov chaw (quanta), uas tso cai rau koj los tswj cov txiaj ntsig ntawm cov emitter ntawm qhov chaw ua haujlwm lossis cov khoom ntawm lub hom phiaj. Ntawm cov yam ntxwv tseem ceeb uas tso cai rau koj los kho cov theem ntawm electrochemical thiab kho qhov muag los ntawm laser, tsom, qib ntawm flux concentration, wavelength, directionality, thiab lwm yam. lub luag hauj lwm - piv txwv li, pulses muaj peev xwm muaj ib tug ncua sij hawm ntawm ib feem thib ob mus rau kaum ntawm femtoseconds nrog intervals li ntawm ib pliag mus rau ob peb xyoos.
Synergic laser qauv
Thaum kaj ntug ntawm lub tswv yim ntawm lub laser kho qhov muag, lub kaw lus ntawm quantum hluav taws xob nyob rau hauv cov ntsiab lus ntawm lub cev feem ntau to taub raws li ib daim ntawv ntawm tus kheej lub koom haum ntawm ntau lub zog Cheebtsam. Yog li, lub tswv yim ntawm kev sib koom ua ke tau tsim, uas ua rau nws muaj peev xwm tsim cov khoom tseem ceeb thiab theem ntawm kev loj hlob ntawm lub laser. Txawm hais tias hom thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub laser, qhov tseem ceeb ntawm nws qhov kev ua yog mus dhau qhov sib npaug ntawm lub teeb atoms, thaum lub kaw lus tsis ruaj khov thiab tib lub sijhawm qhib.
Kev sib txawv hauv qhov sib txawv ntawm qhov sib txawv ntawm cov hluav taws xob tsim cov xwm txheej rau qhov pom ntawm lub suabntws. Tom qab ncav cuag tus nqi ntawm cov twj tso kua mis (kev sib txawv), qhov kho qhov muag quantum generator ntawm cov hluav taws xob sib txuas ua ke tuaj yeem tswj tau thiab hloov mus rau hauv cov qauv kev txiav txim siab nrog cov ntsiab lus ntawm kev tswj tus kheej. Raws li qee qhov xwm txheej, lub cuab yeej tuaj yeem ua haujlwm nyob rau hauv lub tshuab hluav taws xob hluav taws xob hauv lub voj voog, thiab nws cov kev hloov pauv yuav ua rau muaj kev ntxhov siab.
laser ua haujlwm Cheebtsam
Tam sim no nws tsim nyog txav los ntawm lub hauv paus ntsiab lus ntawm kev ua haujlwm mus rau lub cev thiab kev ua haujlwm tshwj xeeb uas lub tshuab laser nrog qee yam ua haujlwm. Qhov tseem ceeb tshaj plaws, los ntawm qhov pom ntawm kev ua haujlwm ntawm optical quantum generators, yog qhov nruab nrab nquag. Los ntawm nws, tshwj xeeb, nyob ntawm qhov kev siv ntawm amplification ntawm qhov ntws, cov khoom ntawm cov lus tawm tswv yim thiab cov teeb liab optical tag nrho. Piv txwv li, hluav taws xob tuaj yeem tshwm sim hauv cov roj sib tov uas feem ntau cov khoom siv laser niaj hnub no ua haujlwm rau.

Lwm qhov yog tias kev ua haujlwm nyob rau hauv cov xwm txheej ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob nrawm nrawm ua rau hnav cov khoom ua haujlwm.
Dye laser ntaus ntawv
Hom tshuab hluav taws xob kho qhov muag no tau tsim lub hauv paus rau kev tsim cov kev taw qhia tshiab hauv laser thev naus laus zis, ua haujlwm nrog lub sijhawm mem tes txog li picoseconds. Qhov no ua tau vim yog siv cov organic dyes ua ib qho nruab nrab, tab sis lwm lub laser, feem ntau yog ib qho argon, yuav tsum ua cov twj tso kua mis.
Raws li rau kev tsim kho qhov muag quantum generators ntawm dyes, lub hauv paus tshwj xeeb nyob rau hauv daim ntawv ntawm cuvette yog siv los muab ultrashort pulses, qhov chaw nqus tau tsim. Cov qauv nrog lub nplhaib resonator nyob rau hauv xws li ib puag ncig tso cai siv cov kua dyeing ntawm speeds mus txog 10 m / s.
Txoj kev ntawm fiber ntau optic emitters
Ib hom laser ntaus ntawv uas ua haujlwm ntawm lub resonator yog ua los ntawm fiber ntau optical. Los ntawm qhov pom ntawm kev khiav hauj lwm cov khoom, lub tshuab hluav taws xob no yog qhov tsim tau zoo tshaj plaws ntawm qhov ntim ntawm cov hluav taws xob kho qhov muag. Thiab qhov no txawm hais tias qhov tsim ntawm lub cuab yeej muaj qhov loj me me piv rau lwm hom lasers.
KCov yam ntxwv ntawm optical quantum generators ntawm hom no kuj muaj xws li versatility nyob rau hauv cov nqe lus ntawm lub possibilities ntawm kev sib txuas cov twj tso kua mis. Feem ntau, tag nrho cov pab pawg ntawm optical waveguides yog siv rau qhov no, uas yog ua ke rau hauv modules nrog ib tug active tshuaj, uas kuj pab mus rau lub structural thiab functional optimization ntawm lub ntaus ntawv.
Kev ua raws li kev tswj hwm
Feem ntau ntawm cov khoom siv yog raws li hluav taws xob, vim tias lub zog siv hluav taws xob tau muab ncaj qha lossis tsis ncaj qha. Hauv cov txheej txheem yooj yim tshaj plaws, los ntawm cov khoom siv hluav taws xob no, cov ntsuas hluav taws xob raug saib xyuas uas cuam tshuam rau qhov kev siv hluav taws xob nyob rau hauv ib qho kev kho qhov muag.
Kev tshaj lij quantum generators kuj muaj qhov tsim kho qhov muag rau kev tswj xyuas ntws. Los ntawm cov qauv zoo li no, tshwj xeeb, cov kev taw qhia ntawm lub nozzle, lub zog thiab qhov ntev ntawm cov mem tes, zaus, qhov kub thiab txias thiab lwm yam kev ua haujlwm raug tswj.
Teb daim ntawv thov ntawm lasers
Txawm hais tias lub tshuab hluav taws xob kho qhov muag tseem yog cov khoom siv uas tseem tsis tau nthuav tawm tag nrho, hnub no nws nyuaj rau npe rau thaj chaw uas lawv yuav tsis siv. Lawv muab kev lag luam muaj txiaj ntsig zoo tshaj plaws los ua cov cuab yeej siv tau zoo rau kev txiav cov khoom siv ntawm tus nqi tsawg.
Optical quantum generators kuj tau siv dav hauv txoj kev kho mob hauv kev cuam tshuam rau qhov muag microsurgery thiab cosmetology. Piv txwv li, universal laserlub npe hu ua bloodless scalpels tau dhau los ua ib qho cuab yeej hauv tshuaj, tso cai tsis yog rau kev txiav, tab sis kuj tseem txuas cov ntaub so ntswg lom.
Zoo kawg
Hnub no, muaj ob peb txoj kev cog lus hauv kev tsim kho qhov muag hluav taws xob hluav taws xob. Cov neeg nyiam tshaj plaws muaj xws li txheej-los ntawm txheej synthesis, nws tau lam ua rau lub tshuab hluav taws xob ntau ntxiv yuav muaj lawv cov ntawv thov tshwj xeeb - los ntawm kev ua haujlwm saum npoo ntawm cov ntaub ntawv thiab ultra-ceev creation ntawm cov khoom sib xyaw kom tua hluav taws los ntawm hluav taws xob.
Pom tseeb, ntau txoj haujlwm nyuaj yuav xav tau kev ua kom lub zog ntawm laser thev naus laus zis, vim tias qhov pib ntawm nws qhov kev phom sij tseem yuav nce ntxiv. Yog tias niaj hnub no qhov laj thawj tseem ceeb ntawm kev ua kom muaj kev nyab xeeb thaum ua haujlwm nrog cov cuab yeej zoo li no yog qhov ua rau muaj kev phom sij rau lub qhov muag, tom qab ntawd peb tuaj yeem tham txog kev tiv thaiv tshwj xeeb ntawm cov khoom siv thiab cov khoom nyob ze uas siv cov cuab yeej tsim.
