Lesetara ke eng?
Ka bokhutšoanyane, laser ke leseli le hlahisoang ke ho sisinyeha ha lintho. 'Me re ka etsa mosebetsi o mongata ka lehlaseli la laser.
Ho Wikipedia, A laserke sesebediswa se ntshang lesedi ka mokgwa wa ho eketsa lesedi ho itshetlehile hodima ho ntsha ha mahlaseli a motlakase a susumeditsweng. Lentswe “laser” ke khutsufatso ya “ho eketsa lesedi ka ho ntsha ha mahlaseli a susumeditsweng”. Laser ya pele e hahilwe ka 1960 ke Theodore H. Maiman ho Hughes Research Laboratories, e itshetlehile hodima mosebetsi wa thuto wa Charles Hard Townes le Arthur Leonard Schawlow.
Lesea e fapane le mehloli e meng ea leseli ka hore e ntša leseli le lumellanang. Ho lumellana ha sebaka ho lumella lesea ho tsepamisa maikutlo sebakeng se thata, ho nolofalletsa lits'ebetso tse kang ho seha ha laser le lithography. Ho lumellana ha sebaka ho boetse ho lumella lebone la laser ho lula le lesesaane libakeng tse telele (collimation), ho nolofalletsa lits'ebetso tse kang li-laser pointers le lidar. Li-laser li ka boela tsa ba le ho lumellana ho hoholo ha nako, e leng se li lumellang ho ntša leseli ka spectrum e nyane haholo. Ntle le moo, ho lumellana ha nako ho ka sebelisoa ho hlahisa li-pulse tse khutšoane haholo tsa leseli ka spectrum e pharaletseng empa nako e khutšoanyane joaloka femtosecond.
