Zivela phi iilaser?

Ithiyori yelaser (Ukwandiswa kweLaser ngokuPhuculwa kweRadiation) yavela kuAlbert Einstein ngo-1917, owalatha uthotho lwethiyori yobugcisa malunga nokusebenzisana phakathi kokukhanya kunye nento (Zur Quantentheorie der Strahlung).

Ngokwethiyori, kukho amanani ahlukeneyo amasuntswana asasazwa kumanqanaba ahlukeneyo amandla. Kwaye amasuntswana akwinqanaba eliphezulu lamandla aya kugxuma kwinqanaba eliphantsi lamandla xa evuyiswa yifoton ethile. Kwinqanaba lamandla aphantsi, ukukhanya kohlobo olufanayo nokukhanya okuvuyisayo kuya kukhanya. Kwaye ukukhanya kweveki kunokuvuyisa ukukhanya okunamandla kwimeko ethile.

Emva koko, uRudolf W.Ladenburg, uValentin A. Fabrikant, uWillis E. imvu, uAlfred Rastler uJoseph Weber kunye nabaphandi abaninzi benza igalelo ekuhlolisweni kwe-lasers.

Namhlanje, ndingathanda ukunikela ingqalelo ngakumbi ekusetyenzisweni kweelaser, njengokusika kwe-laser kunye nokukrola, i-laser welding kunye nokumakishwa kwelaser. Ukusetyenziswa kwe-laser cutting kwaqala ngo-1963, kwakudume ngeenzuzo ezine, ukukhanya okuphezulu, ulwalathiso oluphezulu, i-monochromaticity ephezulu kunye nokuhambelana okuphezulu. Akukho deformation kunye nesixhobo sokunxiba ngexesha lokusebenza kuba i-laser ayidibanisi nezinto zokulungisa. Ngaphaya koko, yinkqubo eguquguqukayo ekhawuleza isike kwaye igqobhoze imathiriyeli yentsimbi ngobunzulu obuphezulu bomqadi kunye namandla anamandla.

Ngaphezu koko, ukuba ukhe weva ukuwelda kwelaser, indawo entsha yokuwelda eqhelekileyo, uyazi ukuba yindlela esebenzayo. Akunjalo nje ngenxa yokuguquguquka okukhulu, kodwa nangenxa yeenzuzo ezibanzi.

Ngokusekwe kumqadi we-laser optical, abasebenzi banokudibanisa imathiriyeli yentsimbi ngaphandle kokuzalisa kunye ne-welding flux. Xa kuthelekiswa ne-argon yendabuko ye-arc welding, eyona ndlela ixhaphakileyo yokuwelda ngoku, i-fiber laser welding inokudlula kwizinto ezibonakalayo, ezinokuthi zithintele kakhulu ukwenzakala kwakhe ngokusetyenzwa okude. Kwaye inokusetyenziswa kwimekobume egqithisileyo, njengobushushu obuphezulu, ukubanda okuphezulu kunye nokusingqongileyo kweradioactive.
