Pazvinhu zvaro, laser pumping ndiyo nzira yekushongedza svikiro kuti uwane nyika kwaunogona kusimbisa laser mwenje. Izvi zvinowanzoitwa nekubvisa mwenje kana zvemagetsi zvazvino kusvika pakati, zvichinakidza maatomu ayo uye kutungamira kuchiedza chechiedza chakabatana. Iyi nzira yekusimudzira yakabva zvakanyanya kubva pakuuya kwevanouya vekutanga pakati pezana ramakore.
Apo kazhinji kazhinji pakati peyero equations, laser pumping inonyanya kukosha chiitiko chekutora. Izvo zvinosanganisira kubatanidzwa kwakaomarara pakati pemufananidzo uye maatomu kana molecular chimiro chegodhi yepakati. Yepamberi Models Funga nezvaPhenomena Senge Rabi Oscillations, iyo inopa kunzwisisa kunonzwisisika kwekudyidzana uku.
Laser kupomba ibasa apo simba, kazhinji mune fomu yechiedza kana magetsi zvazvino, zvinopihwa kune yakawana yekuwana svikiro kusimudza maatomu kana mamorekuru kune yakakwirira simba mamiriro ezvinhu. Uku kuendesa kwesimba kwakakosha kwekuwana huwandu hwehuwandu hwekuita, mamiriro emagetsi anofara kupfuura mune yakaderera simba mamiriro, achigonesa svikiro kuti riwedzere kubuda. Maitiro acho anosanganisira kuwanda kwehuwandu ZVINOKOSHA ZVINOGONESA Sarudzo yePump Sosi (Senge Laser Diodes kana Discharge Lamps (Spectrumzo yePombi), Spectity, Bhurawuti mhando, Polarization) kuenzanisa izvo zvatakafanira zvinodiwa zvekuwana svikiro. Laser kupomba inokosha mumhando dzakasiyana-siyana dzeLaser, kusanganisira yakasimba-nyika, Semiconductor, uye gasi lasers, uye zvakakosha kune ishandire yakashanda uye inoshanda.
Varietsies yeanosemesa lasers lasers
1. Solid-State Lasers ine DEPPED Insululators
· Overview:Iyi lasers inoshandisa iyo yemagetsi inosimbisa svikiro uye kuvimba neyekupomba kupomba kuti isimbise laser-anoshanda ions. Muenzaniso wakajairika ndewekodhi muYag lasers.
·Changobva kutsvagisa:Fundo ne A. Antipov et al. inokurukura sosi yakasimba-padyo ne-IR laser ye spin-yekutsinhana optoclump. Tsvagurudzo iyi inoratidza kufambira mberi mune yakasimba-nyika laser technology, kunyanya mukunyorwa-infrared spectrum, iyo yakakosha kune zvekushandisa senge kuratidzira kufungidzira uye telecommunication.
Kuwedzera kuverenga:Iyo yakasimba-nyika pedyo-ir laser for spin-exchange Optical pumping
2. Semiconductor lasers
·Ruzivo rwese: Kazhinji magetsi emagetsi.
·Zvichangoitika Zvizhinji: U. Basa raKeller pane Optical Frequency Coms kubva kuUstraffer Solid-State Lashigs muReals Kufambira mberi uku kwakakosha kune zvinoshandiswa muOptical frequency metrology.
Kuwedzera kuverenga:Optical Frequency Coms kubva ku Ultraffed Solid-State uye Semiconductor Lasers
3. Gasi lasers
·Optical kupomba mugesi lasers: Dzimwe mhando dzevaridzi gasi, seAlkali vapor lasers, kushandisa optical kupomerwa. Aya laser anowanzo shandiswa mune zvekushandisa anoda zvibodzwa zvakaenzana zvibodzwa zvine zvirevo.
SOURCES yeOptical Pumping
Bvisa mwenje. Ya mandryko et al. Yakagadziridza muenzaniso wemagetsi wekumanikidza Arc disccharge chizvarwa mune anoshanda media Optical pumping xenon marambi akasimba-nyika lasers. Iyi modhi inobatsira kugadzirisa mashandiro ekumanikidza kupomera marambi, akakosha ekushanda kwakanaka laser.
Laser diode:Inoshandiswa muDiode-pumped Lasers, Laser diode inopa zvakanakira sekushanda kwakanyanya, saizi yemuchadenga, uye kugona kuve wakarongeka.
Kuwedzera kuverenga:Chii chinonzi laser diode?
Flash Lamps: Marambi emwenje akanyanya, akajeka-spectrum mwenje anowanzo shandiswa kupomba yakasimba-nyika lasers, senge ruby kana nd: yg lasers. Ivo vanopa zvakanyanya kusimba kwekuputika kwechiedza icho chinonakidza iyo laser svikiro.
Arc marambi. Ivo vanoshandiswa mune zvekushandisa uko kuenderera mberi wave (CW) laser mashandiro anodikanwa.
Lels (mwenje unobvisa diodes). Ivo vanobatsira nekuda kwehupenyu hwavo hwakareba, mutengo wakaderera, uye kuwanikwa mune dzakasiyana siyana wavelengths.
Chiedza. Iyi nzira haina simba reSolar simba, zvichiita kuti isimbe uye inodhura-inobudirira tsime, kunyangwe isinganyanye kuomesesa uye yakaderera yakafanana neyekuzvidza zvinyorwa.
Fiber-Coupled laser diode: Aya ana laser dioed pamwe chete neyekunze fibers, iyo inounza mwenje wepombi zvakanyanya zvinobudirira kune laser yepakati. Iyi nzira inonyanya kubatsira mune fiber lasers uye mumamiriro ezvinhu apo chaiyo yekuunza yechiedza chepombi chakakosha.
Mamwe Lasers: Dzimwe nguva, imwe laser inoshandiswa kupomba imwe. Semuenzaniso, nguva zhinji-mbiri ndima nd: yg laser inogona kushandiswa kupomba dhayi laser. Iyi nzira inowanzoshandiswa kana yakasarudzika wavelengths inodiwa kuti pombi yekupomba iyo isingawanikwe nyore nyore neyakajairika manyorerwo.
Diode-pombi yakasimba-nyika laser
Chekutanga Energy Source: Maitiro acho anotanga neDiode laser, iyo inoshanda seyakaitwa pombi. Diode lasers akasarudzwa pakubata kwavo, saizi yemuchadenga, uye kugona kufungidzira mwenje pane chaiwo wavelengths.
Pombi Chiedza:Diode laser inoburitsa mwenje unobatwa neiyo yakasimba-nyika kuwana svikiro. Iyo wavelength ye dihode laser inogadziriswa kuti ifanane neyekutora hunhu hwehunhu hwesium.
Yakasimba-nyikaWana svikiro
Chinyorwa:Iyo yekuwana svikiro muDPSS Lasers kazhinji inzvimbo yakasimba-nyika yakaita seND: YAG
Doping:Zvigadzirwa izvi zvinoitwa nevashoma-pasi-pasi ion (kunge nd kana yb), ndedzipi dzinoshanda laser ions.
Simba rekunyura uye kufarirwa:Kana iyo pombi yedutu kubva kuDiode Laser inopinda muwani kuti ive svikiro, iyo nyika-yepasi-pasi inobata simba iri uye kufadza kune yakakwirira simba nyika.
Population Inversion
Kuwana Inversion Inversion:Iyo kiyi yeLaser chiito iri kuzadzisa iyo huwandu hwehuwandu mukuwana svikiro. Izvi zvinoreva kuti mamwe oni ari mumamiriro anofadza kupfuura muvhu.
Yakakurudzirwa emission:Kamwe kuwanda kwehuwandu kunowanikwa, kusuma kwePhotoni kunoenderana nemusiyano wepamoyo pakati pevakafara uye nyika dzinotsausa dzidziso yekudzokera kuPround, kuburitsa Photon mune maitiro.
Optical Resonator
Magirazi: Iyo kuwana svikiro yakaiswa mukati meye Optical Resonator, inowanzoumbwa nemagirazi maviri pakupera kwesvikiro.
Mhinduro uye kukwidziridzwa: Imwe yemagirazi inoratidzira zvakanyanya, uye imwe yacho ichiratidzira zvishoma. Photo
Laser
Vakabatana Chiedza: Iwo mafoto anoburitswa ane cohent, zvichireva kuti ivo vari muchikamu uye vane iyo yakafanana wavelength.
Kubuda: Girazi rinoratidzira ririmi rinobvumira imwe yechiedza ichi kuti ipfuure, vachiumba iyo laser danda rinobuda dpss laser.
