Li-laser li tsoa hokae?

Khopolo ea laser(Laser Amplification by Stimulated Emission of Radiation) e hlahile ho Albert Einstein ka 1917, ea ileng a supa letoto la khopolo ea tekheniki mabapi le tšebelisano lipakeng tsa leseli le ntho (Zur Quantentheorie der Strahlung).

Ho ea ka khopolo, ho na le lipalo tse fapaneng tsa likaroloana tse ajoang maemong a fapaneng a matla. 'Me likaroloana tse boemong bo phahameng ba matla li tla tlolela boemong bo tlaase ba matla ha li thabisoa ke photon e itseng. Boemong bo tlase ba matla, khanya ea tlhaho e ts'oanang le ea lebone le e hlasimollang e tla khanya. 'Me leseli la beke le ka hlasimolla leseli le matla sebakeng se itseng.

Ka mor'a moo, Rudolf W.Ladenburg, Valentin A. Fabrikant, Willis E. konyana, Alfred Rastler Joseph Weber le bafuputsi ba bangata ba ile ba kenya letsoho ha ho hlahlojoa lasers.

Kajeno, ke rata ho ela hloko haholo ts'ebeliso ea li-laser, joalo ka ho seha le ho betla ka laser, welding ea laser le ho tšoaea ka laser. Tšebeliso ea laser cutting e qalile ka 1963, e ne e tumme ka melemo e mene, khanya e phahameng, tataiso e phahameng, monochromaticity e phahameng le ho lumellana ho phahameng. Ha ho na deformation le lisebelisoa nakong ea ts'ebetso kaha laser ha e kopane le thepa ea ho sebetsa. Ho feta moo, ke ts'ebetso e feto-fetohang e potlakisang le ho phunya lisebelisoa tsa tšepe ka matla a holimo le matla a matla.

Ho feta moo, haeba o kile oa utloa welding ea laser, phetisetso e ncha ea welding e tloaelehileng, u tla tseba hore ke tsela e sebetsang. Eseng feela ka lebaka la ho ikamahanya le maemo ho hoholo, empa hape ka lebaka la melemo e akaretsang.

Ho ipapisitsoe le lebone la laser la optical, basebetsi ba ne ba ka tjheseletsa thepa ea tšepe ntle le ho tlatsa le mocheso oa welding. Ha ho bapisoa le mokhoa o tloaelehileng oa ho cheselletsa li-argon arc, mokhoa o tloaelehileng oa ho tjheseletsa hona joale, fiber laser welding e ka feta ka har'a lintho tse bonahalang, tse ka thibelang haholo hore a senyehe ke ts'ebetso e hōle. 'Me e ka sebelisoa tikolohong e feteletseng, joalo ka mocheso o phahameng, serame se phahameng le tikoloho ea radioactive.
