Iyo yekutanga inoshanda yekushanda yeiyo laser (Chiedza Chekumusoro nekukurudzirwa kubviswa kweradiation) zvakavakirwa pachiitiko chechiedza chechiedza. Kuburikidza nenhevedzano yezvibodzwa zvakajeka uye zvivakwa, lasers gadzira matanda nekubatana kwakanyanya, monachicity, uye kupenya. Lasers anowanzoshandiswa zvakanyanya muhunyanzvi hwazvino hunyanzvi, kusanganisira mumapoka akadai sekutaurirana, mushonga, kugadzira, kuyerwa, uye kutsvakwa kwesainzi. Kubudirira kwavo kwakanyanya uye hunhu hwekudzora hunovaita ivo chikamu chepakati chetsamba dzakawanda. Pazasi pane tsananguro yakadzama yehunyanzvi hwekushanda dze lasers uye michina yemhando dzakasiyana dze lasers.
1. Yakakurudzirwa kubuda
Yakakurudzirwa kubudandiyo nheyo yakakosha kuseri kweLaser chizvarwa, chekutanga kuratidzwa neEinstein muna 1917. Ichi chiitiko chinotsanangura kuti vakabatanidzwa sei neyakagadzirwa nepakati pechiedza uye vanofara-nyika. Kunzwisisa zviri nani kukwirira kwemakungwa, ngatitangei nekumisikidzwa kwemukati:
Spantaneous emission. Nekudaro, emagetsi ane ruzivo, anozopedzisira adzokera kune yakaderera simba resimba, inozivikanwa seivhu nyika, mushure menguva pfupi. Panguva iyi, magetsi anoburitsa Photon, izvo zvinobuda zvinyoreso. Foto dzakadaro dzakasarudzika maererano neye frequency, chikamu, uye kutungamirirwa, uye nekudaro kushaya condence.
Yakakurudzirwa kubuda. Iyo itsva Photon yakafanana neyekutanga maererano neye frequency, chikamu, uye kutungamira kwekunyepedzera, zvichikonzera kuchiedza chakabatana. Ichi chiitiko chakanyanya kukwidziridza huwandu uye simba remapikicha uye ndiyo core mechanic of lasers.
Yakanaka mhinduro mhedzisiro yekukurudzirwa kusimuka. Nekubatsirwa kwenzvimbo yekuzorora, kuunganidzwa kwemitambo kunochengetwa, uye kusimba kwechiedza chingori kuenderera mberi kwakawedzera.
2. Wana svikiro
The thewana svikirondicho chinhu chakapindirana mu laser icho chinosarudza kukwikwidza kwemifananidzo uye iyo laser inobuda. Iyo ndiyo nheyo yemuviri yekukurudzirwa kwemasvikiro, uye zvivakwa zvayo zvinoona frequency, wavelength, uye simba rekubuditsa reruwa. Iyo mhando uye hunhu hweiyo kuwana yepakati zvakananga kukanganisa iyo application uye kuita kweiyo laser.
Inonakidza Mechanism. Maitiro aya anowanzo kuwanikwa neyekunze simba rekuwanikwa masisitimu. Zviitiko zvakajairika zvinongedzo zvinosanganisira:
Magetsi ekupomba: Inonakidza ma elekitoni mune yekuwana svikiro nekushandisa magetsi aripo.
Optical pumping: Inonakidza svikiro ine mwenje wechiedza (senge mwenje wemwenje kana imwe laser).
Energy levels system. Zvakanyanya kuwandamaviri-mwero masisitimuuyeina-level masystem. Mune iri nyore maviri-nhanho system, elekitori inoshandurwa kubva pasi kubva kune iyo nyika kune iyo inofadza mamiriro uye wozodzokera kuGround State kuburikidza nekukurudzirwa. Mune imwe chete-mwero, elekitari inowedzera shanduko dzakaoma pakati pemazinga akasiyana, kazhinji zvichikonzera kunyatsoita.
Mhando dzekuwana media:
Gasi kuwana pakati: Semuenzaniso, Helium-Neon (iye-ne) lasers. Gasi GADZIRA YEMAHARA DZINOGONESESWA KUTI DZINOGONESESWA YEMAHARA uye Yakasarudzika Watchength
Mvura inowana pakati: Semuenzaniso, dhayi lasers. Dye mamorekuru vane zvinhu zvakanaka zvinoenderana neakasiyana wavelengths, zvichiita kuti vakwanise kuve vakachaira lasers lasers.
Solid Watch Svikiro: Semuenzaniso, nd (neodymium-diping ytttrium aluminium garnet) lasers. Aya lasers anoshanda zvakanyanya uye ane simba, uye anoshandiswa zvakanyanya mukucheka kwemaindasitiri, kutaridzika, uye zvekurapa.
Semicononductor kuwana pakati.
3. Resonator Cavity
The theResonator CavityChimiro chechimiro mune laser inoshandiswa mhinduro uye kukwidziridzwa. Basa rayo repakati nderekuwedzera huwandu hwemapikicha hunogadzirwa kuburikidza nekukurudzirwa nekumisikidza uye nekuvakwidza mukati memukati, nekudaro kugadzira yakasimba uye yakatarisana laser kubuda.
Chimiro cheiyo resonator cavity: Inowanzove nemagirimita maviri akafanana. Imwe girazi rinonyatsoratidza, rinozivikanwa sekumashure girazi, uye imwe yacho igirazi rinoratidza chidimbu, rinozivikanwa sekubuda girazi. Photons inoratidza kudzoka uye kunze mukati memukati marara uye inokudzwa kuburikidza nekudyidzana neiyo svikiro.
Resonance mamiriro. Izvi zvinoda urefu hwekireji kuve hwakawanda hweiyo laser wavelength. Mafungu echiedza chete anosangana nemamiriro aya anogona kunyatso kukwidziridzwa mukati memukati.
Kubuda beam. Iyi danda ine nzira yakakwirira, kuenderana, uye monachicity.
Kana iwe uchida kudzidza zvakawanda kana kufarira lasers, ndapota inzwa wakasununguka kutibata nesu:
