Yintoni i-laser?

Ngamafutshane, i-laser kukukhanya okuveliswa kukukhukuliswa kwezinto. Kwaye singenza umsebenzi omninzi nge-laser beam.

KwiWikipedia, u-A ilezasisixhobo esikhupha ukukhanya ngenkqubo yokukhulisa ukukhanya okusekwe ekukhutshweni kwemitha ye-electromagnetic evuselelayo. Igama elithi “laser” sisifinyezo segama elithi “ukukhulisa ukukhanya ngokukhupha ukukhanya okuvuselelayo”. I-laser yokuqala yakhiwa ngo-1960 nguTheodore H. Maiman kwiHughes Research Laboratories, ngokusekelwe kumsebenzi wethiyori kaCharles Hard Townes kunye no-Arthur Leonard Schawlow.

I-laser yahlukile kweminye imithombo yokukhanya kuba ikhupha ukukhanya okuhambelanayo. Ukuhambelana kwendawo kuvumela i-laser ukuba igxile kwindawo eqinileyo, nto leyo evumela ukusetyenziswa okufana nokusika nge-laser kunye ne-lithography. Ukuhambelana kwendawo kukwavumela umqadi we-laser ukuba uhlale umxinwa kumgama omde (collimation), nto leyo evumela ukusetyenziswa okufana nee-laser pointers kunye ne-lidar. Ii-laser zinokuba nokuhambelana kwexesha eliphezulu, nto leyo evumela ukuba zikhuphe ukukhanya nge-spectrum encinci kakhulu. Ngaphandle koko, ukuhambelana kwexesha kungasetyenziselwa ukuvelisa ii-pulses ezimfutshane kakhulu zokukhanya nge-spectrum ebanzi kodwa ubude bufutshane njenge-femtosecond.

Iilaser zisetyenziswa kwiidiski ze-optical, iiprinta ze-laser, ii-barcode scanners, izixhobo zokulandelelanisa i-DNA, i-fiber-optic, i-semiconducting chip manufacturing (i-photolithography), kunye nonxibelelwano lwe-optical olukhululekileyo, utyando lwe-laser, kunye nonyango lwesikhumba, izixhobo zokusika kunye nokuwelda, izixhobo zomkhosi nezomthetho zokuphawula iithagethi kunye nokulinganisa uluhlu kunye nesantya, kunye nakwimiboniso yezibane ze-laser yokuzonwabisa.

Emva kophuhliso olude lwembali yetekhnoloji yelaser, ilaser ingasetyenziswa kwiindlela ezahlukeneyo zoshishino, kwaye yenye yezona ndlela ziphambili zokusetyenziswa xa kusenziwa ukusika, ngaphandle kwesinyithi, isinyithi okanye imboni engeyiyo yesinyithi, umatshini wokusika ilaser uhlaziya indlela yendabuko yokusika, uphucule ukusebenza kakuhle kwemveliso kwishishini lemveliso, njengempahla, ilaphu, ikhaphethi, umthi, i-acrylic, intengiso, ukusebenza ngesinyithi, iimoto, izixhobo zokomelela kunye nemizi-mveliso yefenitshala.

I-laser ibe sesinye sezona zixhobo zokusika zibalaseleyo ngenxa yeempawu zayo zokusika ezichanekileyo nezikhawulezayo.
