Kunzwisisa Musiyano Uripo Pakati peLaser neChiedza Chakajairika uye Magadzirirwo Anoitwa Laser

Tekinoroji yeLaser yakachinja maindasitiri akasiyana-siyana, kubva pakugadzira zvinhu kusvika pahutano. Asi chii chinoita kuti chiedza cheLaser chisiyane nechiedza chenguva dzose? Chinyorwa chino chinoongorora musiyano mukuru uye maitiro makuru ekugadzira laser.

Kusiyana Pakati peLaser neChiedza Chakajairika

1. Kupenya kwechiedza chimwe chete: Chiedza cheLaser chine kupenya kwechiedza chimwe chete kwakanaka, zvichireva kuti chine urefu hwewavelength imwe chete ine upamhi hwakatetepa hwespectral. Kusiyana neizvi, chiedza chakajairika musanganiswa wema wavelengths akawanda, zvichikonzera kuwanda kwechiedza.

2. Kupenya uye Kuwanda kweSimba: Marara eLaser ane kupenya kwakanyanya uye huwandu hwesimba, zvichivabvumira kuti vaunganidze simba rakawanda munzvimbo diki. Chiedza chakajairika, kunyange chichionekwa, chine kupenya kwakaderera uye huwandu hwesimba rakaderera. Nekuda kwesimba rakawanda remaLaser, mhinduro dzinotonhodza dzinoshanda, dzakadai semaindasitiri emvura anotonhodza, dzakakosha kuti dzirambe dzichishanda zvakanaka uye dzidzivirire kupisa zvakanyanya.

3. Kutungamira: Marara eLaser anogona kupararira nenzira yakafanana, achichengetedza kona diki yekusiyana. Izvi zvinoita kuti marara akwanise kushandiswa nemazvo. Chiedza chakajairika, kune rumwe rutivi, chinopenya munzira dzakasiyana-siyana, zvichikonzera kupararira kukuru.

4. Kubatana: Chiedza cheLaser chinobatana zvakanyanya, zvichireva kuti mafungu acho ane frequency yakafanana, phase, uye divi rekupararira. Kubatana uku kunogonesa mashandisirwo akadai se holography uye fiber optic communication. Chiedza chenguva dzose hachina kubatana uku, nemafungu acho achiratidza mafambiro nematanho asina kurongeka.

Magadzirirwo Echiedza CheLaser

Maitiro ekugadzira laser akavakirwa papfungwa yekusimudzirwa kwemhepo. Anosanganisira matanho anotevera:

1. Kukurudzira Simba: Maatomu kana mamorekuru ari mu laser medium (senge gasi, solid, kana semiconductor) anotora simba rekunze, zvichichinja maerekitironi kuenda kusimba rakakwirira.

2. Kuchinja Kwehuwandu Hwevanhu: Mamiriro ezvinhu anowanikwa kana paine zvidimbu zvakawanda mumamiriro ekufara kupfuura mumamiriro esimba rakaderera, zvichiita kuti kuve nekuchinja kwehuwandu hwevanhu—chinodiwa chakakosha pakuita laser.

3. Kubuda Kwemhepo: Kana atomu rinokurumidza kusangana nephoton inopinda yewavelength chaiyo, rinoburitsa photon yakafanana, zvichiita kuti chiedza chiwedzere.

4. Optical Resonance uye Amplification: Maphotoni anoburitswa anoratidzwa mukati meoptical resonator (magirazi maviri), achiramba achikura sezvo maphotoni akawanda achikurudzirwa.

5. Kubuda kweLaser Beam: Kana simba rasvika padanho rakakosha, danda relaser rinooneka, rinoenda zvakananga rinoburitswa negirazi rinoratidza zvishoma, ragadzirira kushandiswa. Sezvo malaser achishanda pakupisa kwakanyanya, kubatanidza chiller cheindasitiri kunobatsira kudzora tembiricha, kuve nechokwadi chekuti laser inoshanda zvakanaka uye kuwedzera hupenyu hwemuchina.

Mukupedzisa, chiedza chelaser chinosiyana nechiedza chemazuva ese nekuda kwehunhu hwacho hwakasiyana: monochromaticity, high energy density, high directionality, uye coherence. Maitiro chaiwo ekugadzira laser anoita kuti ishandiswe zvakanyanya muminda yemazuva ano senge maindasitiri ekugadzirisa, kuvhiyiwa kwechiremba, uye kutaurirana kwemaziso. Kuti iwedzere kushanda zvakanaka kwesystem yelaser uye kugara kwenguva refu, kushandisa water chiller yakavimbika chinhu chakakosha mukutarisira kugadzikana kwekupisa.
