Kodi laser ndi chiyani? Mfundo ya M'badwo wa Laser

Lasese ndi chimodzi mwazomwe zimapangidwa ndi anthu, zotchedwa "kuwala kowala". M'moyo watsiku ndi tsiku, nthawi zambiri timatha kuwona mapulogalamu osiyanasiyana a laser, monga nyali zokongola, laser yotchedwa, laser udzudzu, opha aser, ndi zina zambiri. Masiku ano, tiyeni timvetse mwatsatanetsatane a Lasers ndi mfundo zomwe zidachokera m'badwo wawo.

Kodi laser ndi chiyani?

Laser ndi gwero lowunikira lomwe limagwiritsa ntchito lasesa kuti apange kuwala kwapadera. Laser amatulutsa kuwala poika mphamvu kuchokera ku gwero loyera lakunja kapena gwero lamphamvu mu zinthuzo kudzera mu radiation.

Laser ndi chipangizo chomata chomwe chimapangidwa ndi sing'anga (monga mpweya, cholimba, kapena madzi) omwe angakulitse kuwala komanso kowoneka bwino. Sing'anga yogwira mu laser nthawi zambiri imakhala chinthu chosankhidwa komanso chokonzedwa, ndipo mawonekedwe ake amangodziwa zomwe zachitika pa laseji.

Kuwala komwe kumapangidwa ndi ma Lasers ali ndi mawonekedwe angapo apadera:

Choyamba, Lasers ndi kuwala kwa monochrotherongotic ndi maulendo okhwimitsa zinthu kwambiri komanso zomwe zingakwaniritse zosowa zina zapadera.

Kachiwiri, laser amawala bwino, ndipo gawo la mafunde owala limakhala logwirizana kwambiri, lomwe limatha kukhalabe ndi mpweya wokhazikika patali kwambiri.

Chachitatu, ma lasers ndi opepuka kwambiri ndi mitengo yopapatiza kwambiri komanso yopingasa bwino kwambiri, yomwe ingagwiritsidwe ntchito kuti ithetse vuto lalikulu.

Laser ndi gwero la kuwala

Mfundo ya M'badwo wa Laser

M'badwo wa laser umaphatikizapo njira zitatu zakuthupi: zolimbikitsidwa, zokha, zomwe zimasoweka, komanso zolimbikitsidwa.

SWolemba ma radiation

Ma radiation olimbikitsidwa ndiye fungulo la m'badwo wa laser. Intaneti ikakhala yosangalatsa kwambiri ndi chithunzi china, imatulutsa chithunzi chomwecho, pafupipafupi, gawo, gawo la polarization, ndi kufalitsa kulowera ku Photon. Njirayi imatchedwa radiation yolimbikitsidwa. Ndiye kuti, chithunzi chino 'chotseka "chithunzi chofanana kudzera mu radiation, potero pezani kuwunikira.

Smpweya wanthawi yomweyo

Atomu, ion, kapena kusintha ma elekitirole a magetsi kuchokera ku mphamvu yayikulu mpaka mphamvu yotsika, imatulutsa zithunzi za mphamvu inayake, yomwe imatchedwa zokhazokha. Kutulutsa kwa zithunzizi ndi kosatheka, ndipo palibe mgwirizano pakati pa zithunzi zomwe zatulutsidwa, zomwe zikutanthauza gawo lawo, boma la polarization, komanso malangizo ofalikira onse ndi achilungamo.

Sotanganidwa

Ma elekitoni atadwala mphamvu zochepa amatenga chithunzi chomwe chili ndi mphamvu yofanana ndi yake, imatha kusangalala ndi mphamvu yayikulu. Njirayi imatchedwa mayamwidwe.

Madzi a Lasers, ma cake cake omwe ali ndi mipata iwiri yofananayo nthawi zambiri imagwiritsidwa ntchito popititsa patsogolo ma radiation olimbikitsidwa. Galasi imodzi ndi galasi yonse yowonetsera, ndipo kalirole kalikonse ndi kaliwiri yotsimikizika, yomwe imatha kulola gawo la laser kuti lidutse.

Akakons mu lasekani sing'anga amawonetsa mmbuyo ndikuwonekera pakati pa magalasi awiri, ndipo chiwonetsero chilichonse chimatulutsa zithunzi zambiri kudzera mu radiation njira yama radiation, potero pezani Kukula kwa Kuwala. Kuwala kwa kuwala kumakulirakulira pamlingo wina, laser amapangidwa kudzera mu semi yowonetsa galasi.
