Iyini i-laser?

Ngamafuphi, i-laser ukukhanya okukhiqizwa yi-excitation of matter. Futhi singenza umsebenzi omningi nge-laser beam.

Ku-Wikipedia, u-A laseriyithuluzi elikhipha ukukhanya ngenqubo yokukhulisa ukukhanya okusekelwe ekukhishweni okukhuthazwa kwemisebe kazibuthe. Igama elithi “laser” liyisifinyezo se-“light amplification by stimulated emission of radiation”. I-laser yokuqala yakhiwa ngo-1960 ngu-Theodore H. Maiman e-Hughes Research Laboratories, ngokusekelwe emsebenzini wetiyori ka-Charles Hard Townes no-Arthur Leonard Schawlow.

Ilaser ihlukile kweminye imithombo yokukhanya ngoba ikhipha ukukhanya okuhambisanayo. Ukuhambisana kwendawo kuvumela i-laser ukuthi igxile endaweni eqinile, okuvumela izinhlelo zokusebenza ezifana nokusika i-laser kanye ne-lithography. Ukuhambisana kwendawo futhi kuvumela i-laser beam ukuthi ihlale incane kumabanga amade (ukungqubuzana), okuvumela izinhlelo zokusebenza ezifana nezikhombisi ze-laser nesivalo. Ama-Lasers nawo angaba nokuhlangana okuphezulu kwesikhashana, okuwavumela ukuthi akhiphe ukukhanya nge-spectrum emincane kakhulu. Okunye, ukuhambisana kwesikhashana kungasetshenziswa ukukhiqiza ama-ultrashort pulses okukhanya ane-spectrum ebanzi kodwa ubude besikhathi bube bufushane njenge-femtosecond.

Ama-Lasers asetshenziswa kuma-optical disc drives, amaphrinta e-laser, izikena zebhakhodi, izinsimbi zokulandelana kwe-DNA, i-fiber-optic, ukukhiqizwa kwe-semiconducting chip (i-photolithography), kanye nokuxhumana kwe-optical space yamahhala, ukuhlinzwa nge-laser, nokwelashwa kwesikhumba, izinto zokusika nokushisela, ezempi kanye amadivaysi omthetho wokumaka okuqondiwe kanye nebanga lokulinganisa nesivinini, kanye nezibonisi zokukhanyisa nge-laser zokuzijabulisa.

Ngemuva kokuthuthukiswa okude komlando kobuchwepheshe be-laser, i-laser ingasetshenziswa embonini yesicelo ehlukene kakhulu, futhi enye yezinguquko ezisetshenziswa kakhulu uma imboni yokusika, ayikho insimbi embonini yensimbi noma engeyona eyensimbi, umshini wokusika laser ubuyekeze indlela yokusika yendabuko, ukuthuthukisa ukusebenza kahle okuningi kokukhiqiza embonini yokukhiqiza, njengezingubo, izindwangu, ukhaphethi, ukhuni, i-acrylic, ukukhangisa, ukwenza insimbi, izimoto, okokusebenza kokuqina nezimboni zefenisha.

I-Laser yaba elinye lamathuluzi angcono kakhulu okusika imbangela yezici zayo zokusika ezinembile nezinesivinini esikhulu.
