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 kwamahhala kwe-optical space, ukuhlinzwa nge-laser, nokwelashwa kwesikhumba, izinto zokusika nokushisela, amasosha kanye namadivayisi omthetho wokumaka okuhlosiwe kanye nokulinganisa uhla lokukhanya nesivinini, kanye nokuzijabulisa nge-laser.

Ngemuva kokuthuthukiswa okude komlando kobuchwepheshe be-laser, i-laser ingasetshenziswa ekusetshenzisweni kwemboni ehlukene kakhulu, futhi enye yezinguquko ezisetshenziswa kakhulu uma imboni yokusika, akukho nsimbi embonini yensimbi noma engeyona eyensimbi, umshini wokusika we-laser uvuselela indlela yokusika yendabuko, uthuthukise ukusebenza kahle okuningi kokukhiqiza embonini yokukhiqiza, njengengubo, izindwangu, ukhaphethi, izinkuni, i-acrylic, isikhangiso, ukusebenza kwensimbi, imoto, imishini yokuqina kanye nefenisha.

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