Kuyini i-laser?

Ngamafuphi, i-laser ukukhanya okukhiqizwa ukuvusa izinto. Futhi singenza umsebenzi omningi ngomsebe we-laser.

Ku-Wikipedia, A i-laseriyithuluzi elikhipha ukukhanya ngenqubo yokukhulisa ukukhanya okusekelwe ekukhishweni kwemisebe kagesi okushukunyiswayo. Igama elithi “laser” liyisifinyezo se-“light amplification by stimulated emission of radiation”. I-laser yokuqala yakhiwa ngo-1960 nguTheodore H. Maiman eHughes Research Laboratories, ngokusekelwe emsebenzini wethiyori kaCharles Hard Townes no-Arthur Leonard Schawlow.

I-laser ihlukile kweminye imithombo yokukhanya ngoba ikhipha ukukhanya okuvumelanayo. Ukuhlangana kwendawo kuvumela i-laser ukuthi igxile endaweni eqinile, okuvumela izinhlelo zokusebenza ezifana nokusika kwe-laser kanye ne-lithography. Ukuhlangana kwendawo kuvumela futhi umsebe we-laser ukuthi uhlale umncane emabangeni amade (collimation), okuvumela izinhlelo zokusebenza ezifana nama-laser pointers kanye ne-lidar. Ama-Laser angaba nokuhlangana okuphezulu kwesikhathi, okuvumela ukuthi akhiphe ukukhanya nge-spectrum encane kakhulu. Ngaphandle kwalokho, ukuhlangana kwesikhathi kungasetshenziswa ukukhiqiza ama-pulse amafushane kakhulu okukhanya nge-spectrum ebanzi kodwa ubude bufushane njenge-femtosecond.

Ama-laser asetshenziswa kuma-drive e-optical disc, kumaphrinta e-laser, kuma-barcode scanner, kuma-DNA sequencing instruments, kuma-fiber-optic, kuma-semiconducting chip manufacturing (photolithography), kanye nokuxhumana kwe-optical okukhululekile, ukuhlinzwa kwe-laser, kanye nokwelashwa kwesikhumba, izinto zokusika nokushisela, amadivayisi ezempi nawokugcina umthetho okubeka uphawu kuma-targets kanye nokulinganisa ububanzi kanye nesivinini, kanye nasezibonisweni zokukhanyisa nge-laser zokuzijabulisa.

Ngemva kokuthuthukiswa kwesikhathi eside kobuchwepheshe be-laser, i-laser ingasetshenziswa ezinhlotsheni ezahlukene zezimboni, futhi ingenye yezindlela ezishintsha kakhulu uma imboni yokusika, ingenansimbi noma imboni engeyona eyensimbi, umshini wokusika i-laser uvuselela indlela yokusika yendabuko, uthuthukise ukusebenza kahle kokukhiqiza embonini yemikhiqizo, njengezingubo, izindwangu, ukhaphethi, ukhuni, i-acrylic, isikhangiso, ukusebenza ngensimbi, izimoto, imishini yokufaneleka kanye nezimboni zefenisha.

I-Laser yaba ngelinye lamathuluzi okusika amahle kakhulu ngenxa yezici zayo zokusika ezinembile kakhulu nezisheshayo.
