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.

I-Lasers isetyenziswa kwi-optical disc drives, iiprinta ze-laser, ii-barcode scanners, izixhobo zokulandelelana kwe-DNA, i-fiber-optic, i-semiconducting chip production (i-photolithography), kunye ne-free-space optical communication, utyando lwe-laser, kunye nonyango lwesikhumba, izixhobo zokusika kunye ne-welding, izixhobo zomkhosi kunye nokuthotyelwa komthetho zokumakisha iithagethi kunye nokulinganisa uluhlu kunye nesantya sokukhanya kunye nokuboniswa kwe-laser.

Emva kophuhliso lwembali yetekhnoloji yelaser, i-laser ingasetyenziswa kwisicelo seshishini esahlukileyo, kwaye enye yezona zinto zisetyenziselwa ukuguqula ishishini, akukho ntsimbi yesinyithi okanye imveliso engeyiyo eyentsimbi, ukuhlaziya umatshini wokusika we-laser indlela yokusika yemveli, ukuphucula ukusebenza kakuhle kwemveliso kwishishini lemveliso, njengempahla, impahla, ilaphu, ikhaphethi, umthi, i-acrylic, intengiso, ukwenza isinyithi, imoto, izixhobo zempilo kunye nefenitshala.

I-Laser yaba sesinye sezona zixhobo zibalaseleyo zokusika ezibangela ukuchaneka okuphezulu kunye neempawu zokusika ngesantya esiphezulu.
