Mfundo yofunika kwambiri ya laser (kukulitsa kuunika polimbikitsa kutulutsa kwa radiation) kumakhazikitsidwa pazinthu zolimbikitsira zoponderezedwa. Kupyola zingapo mwazopanga mwanzeru, ma lasers amapanga mauta okhala ndi mgwirizano, monochromomicaticity, ndi kuwala. Lasers amagwiritsidwa ntchito kwambiri muukadaulo wamakono monga kulumikizana monga kulumikizana, mankhwala, kupanga, muyeso, kuchuluka kwa asayansi. Kuchita kwawo kwakukulu komanso machitidwe owongolera omwe amawongolera amawapangitsa kuti apatse zigawo zambiri. Pansipa pali mwatsatanetsatane mfundo zogwiritsira ntchito za lasers ndi njira zamitundu yosiyanasiyana ya ma lasers.
1. Kutulutsa kolimbikitsidwa
Kutulutsa kosonkhezeredwandiye mfundo yofunika kwambiri m'badwo wa laser, yomwe idafunsidwa koyamba ndi Einstein mu 1917. Izi zikufotokoza kuti zithunzi zogwirizana kwambiri zimapangidwa kudzera mu nkhani yopepuka. Kumvetsetsa bwino zoponderezedwa, tiyeni tiyambire mwachangu:
Kutulutsa kwadzidzidzi: M'ma atomu, mamolekyulu, kapena ma microscopic ena, ma elekitironi amatha kuyamwa mphamvu zakunja (monga mphamvu zamagetsi kapena zamagetsi) ndi mphamvu yokwera kwambiri, yotchedwa State. Komabe, ma elekitole osangalatsidwa ndi maboma aboma ndi osakhazikika ndipo pambuyo pake adzabweranso ku malire amphamvu, omwe amadziwika kuti ndi nthawi yochepa. Panthawi imeneyi, ma elekitoni amatulutsa chithunzi, chomwe chiripo zokha. Machewa oterewa amakhala osavomerezeka malinga ndi pafupipafupi, gawo, ndi kuwongolera, motero zimagwirizana.
Kutulutsa kosonkhezeredwa: Chinsinsi chakusonkhezera kuchonderezedwa ndikuti pamene electon yomwe ikukhudzana ndi Photon ndi Mphamvu yofanizira mphamvu yake yosinthira, chithunzicho chikhoza kupangitsa electon kuti ibwerere kunthaka yakaleyo ndikumasula chithunzi chatsopano. Photon yatsopanoyi ndi yofanana ndi yoyambira mu pafupipafupi, gawo, ndi kufalikira, zomwe zimapangitsa kuwala kogwirizana. Izi zotere zimachulukitsa chiwerengero ndi mphamvu za actons ndipo ndi njira yodutsa lasers.
Zovuta Zabwino za Kutulutsa Kwakusangalatsidwa: Popanga ma lasers, njira zolimbikitsira zimabwerezedwa kangapo, ndipo zotsatira zabwino izi zitha kukuwonjezeranso zithunzi. Mothandizidwa ndi ngalande yosiyanirana, kuphatikiza kwa buledi kumasungidwa, ndipo kukula kwa mtanda mosalekeza.
2. Pezani sing'anga
Apezani pakatiNdi zinthu zoyambira pamaser yomwe imatsimikiza kupezeka kwa zithunzi ndi zotulutsa za laser. Ndi chifukwa chakuthupi cholimbikitsira, ndipo mawonekedwe ake amafotokoza pafupipafupi, mafunde am'dziko lonse, ndi mphamvu yotulutsa laser. Mtundu ndi mawonekedwe a zomwe zimapindulitsa mwachindunji zimakhudzanso ntchito ndi magwiridwe antchito a laser.
Njira Yosangalatsa: Electrons mu diseji imafunikira kusangalala ndi mphamvu zapamwamba ndi gwero lakunja. Izi nthawi zambiri zimatheka ndi mphamvu zakunja machitidwe. Njira zodziwika bwino zimaphatikizapo:
Kupukuta wamagetsi: Kusangalatsa ma elekitironi mu phindu pogwiritsa ntchito magetsi.
Kupopera kwamaso: Kusangalatsa sing'anga ndi gwero lowunikira (monga nyali kapena nyali ina).
Dongosolo lamphamvu: Electrons mu phindu imagawidwa nthawi zambiri m'magetsi. Zofala kwambiriMakina AwirindiMakina Amiyendo Awiri. Mu dongosolo losavuta la ma elekitala, kusintha ma elekitoni kuchokera kunthaka kupita ku State State ndikubwerera pansi ndikubwerera pansi kudzera kokonjezeka. Mu dongosolo la magawo anayi, ma elekitilo amasinthanso zovuta pakati pa magawo osiyanasiyana, nthawi zambiri amabweretsa bwino kwambiri.
Mitundu ya Phunziro:
Gasi amalandilaMwachitsanzo: mwachitsanzo, helium-neon (he-ne) lasers. Mafuta amadziwika kuti amadziwika chifukwa cha zotulukapo zawo zokhazikika ndi mafunde ake, ndipo amagwiritsidwa ntchito ngati magwero ozungulira mu labotaries.
Madzi amapezaMwachitsanzo: Mwachitsanzo, a utoto. Mamolekyulu a utoto ali ndi katundu wabwino kwambiri pamitundu yosiyanasiyana, kuwapangitsa kukhala abwino kuti atulutsidwe a lasers.
Cholimba kuti muchepetseMwachitsanzo: mwachitsanzo, ND (Newdymium-doptium yttrium alminium adyen). Lasers awa ndi othandiza kwambiri komanso amphamvu, ndipo amagwiritsidwa ntchito podulira mafakitale, kuwotcherera, ndi ntchito zamankhwala.
Semiconductor amapeza sing'angaMwachitsanzo: Mwachitsanzo, gallium warnide (Gaas) zinthu zimagwiritsidwa ntchito kwambiri polumikizirana ndi zida za Optoectronic monga Diode ya Laser.

Amasinthidwe amkatindi chinthu chopangidwa mu laser chomwe chimagwiritsidwa ntchito poyankha ndikukulitsa. Ntchito yake yolumikizana ndikuwonjezera chiwerengero cha zithunzi zomwe zimapangidwa kudzera pakuwonetsa ndikuwakulitsa mkati mwa khola, motero kupanga zotulutsa zolimbitsa thupi komanso zowoneka bwino.
Kapangidwe ka zikwangwani: Nthawi zambiri zimakhala ndi magalasi awiri ofanana. Imodzi ndi galasi lowoneka bwino, lomwe limadziwika kutikalasi yakumbuyo, ndipo inayo ndi galasi yowoneka bwino, yotchedwagalasi lotulutsa. Photons amakumbukira zakumbuyo ndikupita mkati mwake ndikukula kudzera mu kulumikizana ndi sing'anga.
Kusinthana: Kapangidwe ka mdindo wopondereza kumayenera kukumana ndi zinthu zina, monga kuonetsetsa kuti zithunzi zimapanga mafunde am'mbali. Izi zimafuna kutalika kwake kukhala kosavuta kambiri ka dissetion. Mafunde Opepuka Omwe Amakwaniritsa izi zitha kukhala bwino mkati mwa kholo.
Kutulutsa Mng'oma: Galasi yowoneka bwino imalola gawo la kuwala kwa Bkulidwe kuti lizidutsa, ndikupanga mtengo wa laser. Nyengoyi imagwirizana kwambiri, kuphatikiza, komanso mononcho.
Ngati mukufuna kuphunzira zambiri kapena chidwi ndi Lasers, chonde khalani omasuka kulumikizana nafe:
