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 mwenje ine yakanakisa monochromaticity, zvichireva kuti ine imwechete wavelength ine yakanyanya kutetepa spectral mutsara. Kusiyana neizvi, chiedza chakajairwa musanganiswa wemasaisai akawanda, zvichiita kuti pave nehupamhi hwakakura.

2. Kupenya uye Simba Density: Laser matanda ane kupenya kwakanyanya uye simba density, zvichivabvumira kuti vatarise simba rakasimba mukati menzvimbo diki. Chiedza chakajairika, chichiri kuoneka, chine kupenya kwakaderera uye kudzika kwesimba. Nekuda kweiyo yakakwira simba rekubuda kwema lasers, inobudirira kutonhora 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. Chiedza chakajairika, kune rumwe rutivi, chinopenya munzira dzakawanda, zvichitungamira mukupararira kukuru.

4. Kubatana: Laser mwenje inobatana 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. Energy Excitation: Maatomu kana mamorekuru ari mulaser medium (senge gasi, solid, kana semiconductor) anotora simba rekunze, achishandura maerekitironi kuenda kusimba repamusoro.

2. Population Inversion: Mamiriro anowanikwa apo mamwe zvidimbu zviripo munzvimbo inonakidza kupfuura munzvimbo yakaderera yesimba, ichigadzira huwandu hwevanhu-chinodiwa chakakosha kuita laser chiitiko.

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

4. Optical Resonance uye Amplification: Iwo mafotoni akaburitswa anoratidza mukati meoptical resonator (peya yezvionioni), ichiramba ichiwedzera sezvo mamwe mafotoni anokurudzirwa.

5. Laser Beam Output: Kana simba rasvika pachikumbaridzo chakakomba, danda rakabatana, rinotungamira laser rinoburitswa kuburikidza negirazi rinoratidza zvishoma, rakagadzirira kushandiswa. Sezvo lasers inoshanda pakupisa kwakanyanya, kubatanidza an industrial chiller  inobatsira 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, kuvhiya kwekurapa, uye kutaurirana kwemaziso. Kukwirisa laser system inoshanda uye hupenyu hurefu, kuita yakavimbika mvura chiller chinhu chakakosha mukugadzirisa kugadzikana kwekupisa.
