Ukuqonda Umehluko Phakathi Kwe-Laser Nokukhanya Okujwayelekile kanye Nendlela I-Laser Ekhiqizwa Ngayo

Ubuchwepheshe be-laser buguqule izimboni ezahlukene, kusukela kwezokukhiqiza kuye kwezokunakekelwa kwezempilo. Kodwa yini eyenza ukukhanya kwe-laser kuhluke ekukhanyeni okuvamile? Lesi sihloko sihlola ukuhlukaniswa okubalulekile kanye nenqubo eyisisekelo yokukhiqizwa kwe-laser.

Umehluko Phakathi kweLaser kanye Nokukhanya Okuvamile

1. I-Monochromaticity: Ukukhanya kwe-laser kune-monochromaticity enhle kakhulu, okusho ukuthi iqukethe ubude begagasi obubodwa obunobubanzi bomugqa obuncane kakhulu be-spectral. Ngokuphambene, ukukhanya okuvamile kuyingxube yamaza amaza amaningi, okuholela ku-spectrum ebanzi.

2. Ukugqama Nokuqina kwamandla: Imishayo ye-laser inokukhanya okuphezulu okukhethekile namandla aminyana, okuwavumela ukuthi agxilise amandla amakhulu endaweni encane. Ukukhanya okuvamile, ngenkathi kubonakala, kunokukhanya okuphansi kakhulu nokugxila kwamandla. Ngenxa yokukhishwa kwamandla okuphezulu kwama-lasers, izixazululo ezisebenzayo zokupholisa, njengezikhiqizi zamanzi zezimboni, zibalulekile ukuze kugcinwe ukusebenza okuzinzile nokuvimbela ukushisa ngokweqile.

3. Ukuqondisa: Imishayo ye-laser ingasakazeka ngendlela ehambisana kakhulu, igcine i-engeli encane yokuhluka. Lokhu kwenza ama-laser alungele izinhlelo zokusebenza ezinembayo. Ukukhanya okuvamile, ngakolunye uhlangothi, kukhanya ngezindlela eziningi, okuholela ekuhlakazekeni okuphawulekayo.

4. Ukuhambisana: Ukukhanya kwe-laser kuhambisana kakhulu, okusho ukuthi amagagasi ayo anemvamisa efanayo, isigaba, kanye nendlela yokusabalalisa. Lokhu kuhlangana kwenza izinhlelo zokusebenza ezifana ne-holoography kanye nokuxhumana kwe-fiber optic. Ukukhanya okuvamile akunakho lokhu kuhambisana, namagagasi ako abonisa izigaba nezikhombisi-ndlela ezingahleliwe.

Indlela I-Laser Light Ekhiqizwa ngayo

Inqubo yokukhiqiza i-laser isekelwe kumgomo wokukhishwa okukhuthazwayo. Kuhilela izinyathelo ezilandelayo:

1. I-Energy Excitation: Ama-athomu noma ama-molecule endaweni ye-laser (njengegesi, okuqinile, noma i-semiconductor) amunca amandla angaphandle, ama-electron ashintshayo aye kusimo samandla aphezulu.

2. Ukuguqulwa Kwabantu: Kufinyelelwa isimo lapho izinhlayiya eziningi zikhona esimweni senjabulo kunasesimeni esiphansi samandla, okudala ukuguquguquka kwenani labantu—imfuneko ebalulekile yesenzo se-laser.

3. Ukukhishwa Okukhuthazwayo: Uma i-athomu ejabulile ihlangana ne-photon engenayo yobude obuthile be-wavelength, ikhipha i-photon efanayo, ikhulise ukukhanya.

4. I-Optical Resonance kanye Nokukhulisa: Amaphothoni akhishiwe abonisa ngaphakathi kwe-optical resonator (ipheya lezibuko), ekhula ngokuqhubekayo njengoba ama-photon engeziwe ekhuthazwa.

5. I-Laser Beam Output: Uma amandla efinyelela embundwini obalulekile, i-laser beam ehambisanayo, eqonde kakhulu ikhishwa ngesibuko esibonakalisa ingxenye, esilungele ukusetshenziswa. Njengoba ama-laser asebenza emazingeni okushisa aphezulu, ahlanganisa i i-industrial chiller  isiza ukulawula izinga lokushisa, iqinisekisa ukusebenza kwe-laser okungaguquki kanye nokwelula impilo yemishini.

Sengiphetha, ukukhanya kwe-laser kuhlukile ekukhanyeni okuvamile ngenxa yezakhiwo zakho ezihlukile: i-monochromaticity, ukuminyana kwamandla aphezulu, ukuqondiswa okuhle kakhulu, nokuhambisana. Indlela eqondile yokukhiqiza i-laser ivumela ukusetshenziswa kwayo kabanzi emikhakheni esezingeni eliphezulu njengokucubungula izimboni, ukuhlinzwa kwezokwelapha, kanye nokuxhumana ngombono. Ukuze kuthuthukiswe ukusebenza kahle kwesistimu ye-laser nokuphila isikhathi eside, ukusebenzisa isibandisi samanzi esithembekile kuyisici esibalulekile ekulawuleni ukuzinza kwe-thermal.
