Kunzwisisa Misiyano Pakati peLaser uye Chiedza Chenguva uye Kuti Laser Inogadzirwa Sei

Laser tekinoroji yakashandura maindasitiri akasiyana, kubva mukugadzira kuenda kune hutano. Asi chii chinoita kuti mwenje welaser usiyane nemwenje wakajairwa? Ichi chinyorwa chinoongorora misiyano yakakosha uye yakakosha maitiro ekugadzirwa kwelaser.

Musiyano Pakati Laser uye Ordinary Chiedza

1. Monochromaticity: Laser light ine yakanakisa monochromaticity, zvichireva kuti ine yewavelength imwe chete ine mutsetse wakatetepa zvakanyanya. Kusiyana neizvi, chiedza chakajairwa musanganiswa wemasaisai akawanda, zvichiita kuti pave nehupamhi hwakakura.

2. Kupenya uye Simba Density: Laser matanda ane yakasarudzika kupenya kwepamusoro uye simba density, achiabvumira kuisa simba rakasimba mukati menzvimbo diki. Chiedza chakajairika, chichiri kuoneka, chine kupenya kwakaderera uye kudzika kwesimba. Nekuda kweiyo yakakwira simba kuburitsa lasers, inoshanda yekutonhora mhinduro, senge maindasitiri emvura inotonhorera, yakakosha kuchengetedza kushanda kwakagadzikana uye kudzivirira kupisa.

3. Directionality: Laser matanda anogona kupararira nenzira yakanyatsoenderana, kuchengetedza diki divergence angle. Izvi zvinoita kuti lasers ive yakanaka kune chaiyo maapplication. Chiedzawo zvacho, kune rumwe rutivi, chinopenya munzira dzakawanda, zvichitungamirira kukupararira kukuru.

4. Kubatana: Chiedza cheLaser chakabatana zvakanyanya, zvichireva kuti masaisai ayo ane yunifomu frequency, chikamu, uye kuparadzira gwara. Kubatana uku kunoita kuti zvikumbiro zvakaita seholography uye fibre optic communication. Chiedzawo zvacho chinoshaya kubatana uku, nemasaisai acho achiratidza zvikamu zvisina tsarukano nemakwara.

Magadzirirwo eLaser Chiedza

Iyo nzira yekugadzirwa kwelaser yakavakirwa pamusimboti wekukurudzira kubuda. Zvinosanganisira matanho anotevera:

1. Kuwedzeredza Kwesimba: Maatomu kana mamorekuru mune laser medium (yakadai segasi, yakasimba, kana semiconductor) inotora simba rekunze, inoshandura maerekitironi kune yakakwirira simba simba.

2. Population Inversion: Chimiro chinowanikwa apo zvidimbu zvakawanda zviripo mumamiriro emufaro kupfuura munzvimbo yakaderera yesimba, zvichiita kuti vanhu vawedzere-chinodiwa chakakosha pakuita kwelaser.

3. Stimulated Emission: Kana atomu iri kufara ikasangana nefotoni iri kuuya yewavelength chaiyo, inoburitsa fotoni yakafanana, ichikudza chiedza.

4. Optical Resonance uye Amplification: Mapikicha anobudiswa anoratidza mukati meoptical resonator (peya yezvionioni), ichiramba ichiwedzera sezvo mamwe mafotoni ari kukurudzirwa.

5. Laser Beam Output: Kana simba rasvika pachikumbaridzo chakakomba, rakabatana, rakanyatsotungamira laser beam rinobudiswa kuburikidza negirazi rinoratidzira zvishoma, rakagadzirira kushandiswa. Sezvo ma lasers anoshanda pakupisa kwakanyanya, kubatanidza chiller yeindasitiri kunobatsira kudzora tembiricha, kuve nechokwadi chekuenderana kwelaser kuita uye kuwedzera hupenyu hwemidziyo.

Mukupedzisa, laser mwenje inomira kure neyakajairwa mwenje nekuda kweiyo yakasarudzika zvimiro: monochromaticity, yakakwirira simba density, yakanakisa kutungamira, uye kubatana. Iyo chaiyo nzira yekugadzira laser inogonesa kushandiswa kwayo kwakapararira mukucheka-kumucheto minda senge maindasitiri kugadzirisa, kuvhiyiwa kwekurapa, uye kutaurirana kwemaziso. Kukwirisa laser system kunyatsoshanda uye hupenyu hurefu, kuita yakavimbika mvura chiller chinhu chakakosha mukugadzirisa kugadzikana kwekupisa.
