Yintoni i-laser?
Ngamafutshane, i-laser kukukhanya okuveliswa yi-excitation of matter.Kwaye sinokwenza umsebenzi omninzi ngomqa welaser.
KwiWikipedia, uA lasersisixhobo esikhupha ukukhanya ngenkqubo yokukhulisa ukukhanya okusekwe kuvuselelo lokukhutshwa kwemitha ye-electromagnetic.Igama elithi “laser” sisishunqulelo se-“light amplification by stimulated emission of radiation”.I-laser yokuqala yakhiwa ngo-1960 nguTheodore H. Maiman kwi-Hughes Research Laboratories, ngokusekelwe kumsebenzi wethiyori nguCharles Hard Townes kunye no-Arthur Leonard Schawlow.
Ilaser yahlukile kweminye imithombo yokukhanya kuba ikhupha ukukhanya okuhambelanayo.Ukuhambelana kwendawo kuvumela i-laser ukuba igxininise kwindawo eqinile, eyenza izicelo ezifana ne-laser cutting kunye ne-lithography.Ukuhambelana kwendawo kukwavumela umqadi welaser ukuba uhlale umxinwa kumgama omde (ukungqubana), uvumela usetyenziso olufana nezikhombisi zelaser kunye nelidar.I-Lasers inokuba nokuhambelana okuphezulu kwexesha, okubavumela ukuba bakhuphe ukukhanya kunye ne-spectrum emxinwa kakhulu.Kungenjalo, ulungelelwaniso lwexeshana lungasetyenziselwa ukuvelisa i-ultrashort pulses yokukhanya ene-spectrum ebanzi kodwa ubude bufutshane njenge-femtosecond.
IiLasers zisetyenziswa kwi-optical disc drives, abashicileli belaser, iibarcode scanners, DNA sequencing instruments, fiber-optic, semiconducting chip production (photolithography), kunye nesithuba esikhululekileyo sonxibelelwano lwe-optical, utyando lwelaser, kunye nonyango lwesikhumba, ukusika kunye nezixhobo zokuwelda, emkhosini kunye izixhobo zokuthotyelwa komthetho zokumakisha iithagethi kunye noluhlu lokulinganisa kunye nesantya, kunye ne-laser lighting displays ukuzonwabisa.
Emva kophuhliso olude lwembali yobugcisa be-laser, i-laser ingasetyenziswa kwisicelo seshishini esahlukileyo, kwaye enye yezona zinto zisetyenziswa kakhulu kwishishini lokusika, akukho ntsimbi kwishishini lesinyithi okanye elingeyontsimbi, ukuhlaziya umatshini wokusika we-laser indlela yokusika yemveli, kuphucula ukusebenza kakuhle kwemveliso kwishishini lemveliso, njengempahla, ilaphu, ikhaphethi, umthi, i-acrylic, intengiso, ukwenza isinyithi, inqwelo-mafutha, izixhobo zokomelela kunye nemizi-mveliso yefenitshala.
I-Laser yaba sesinye sezona zixhobo zibalaseleyo zokusika ezibangela ukuchaneka okuphezulu kunye neempawu zokusika ngesantya esiphezulu.
