Kodi ma lasers adachokera kuti?

Chiphunzitso cha laser (Laser Amplification by Stimulated Emission of Radiation) chinachokera kwa Albert Einstein mu 1917, yemwe adaloza malingaliro angapo aukadaulo okhudza kulumikizana pakati pa kuwala ndi zinthu (Zur Quantentheorie der Strahlung).

Malinga ndi chiphunzitsocho, pali mitundu yosiyanasiyana ya tinthu tating'onoting'ono tomwe timagawira pamagulu osiyanasiyana amphamvu. Ndipo tinthu tating'onoting'ono tamphamvu timalumphira kumlingo wochepa wa mphamvu mukasangalatsidwa ndi chithunzi china. Pa mlingo wochepa wa mphamvu, kuwala kwa chikhalidwe chofanana ndi kuwala komwe kumakondweretsa kudzawonekera. Ndipo kuwala kwa sabata kumatha kusangalatsa kuwala kwamphamvu mumtundu wina.

Pambuyo pake, Rudolf W.Ladenburg, Valentin A. Fabrikant, Willis E. mwanawankhosa, Alfred Rastler Joseph Weber ndi ofufuza ambiri adathandizira pakufufuza kwa lasers.

Lero, Ndikufuna kulabadira kwambiri kugwiritsa ntchito lasers, monga laser kudula ndi chosema, laser kuwotcherera ndi laser chodetsa. Kugwiritsa ntchito laser kudula kunayamba mu 1963, kunali kotchuka ndi zabwino zinayi, kupepuka kwakukulu, kuwongolera kwakukulu, kukhazikika kwapamwamba komanso kulumikizana kwakukulu. Palibe mapindikidwe ndi zida zobvala panthawi ya opaleshoni popeza laser samalumikizana ndi zinthu zopangira. Kupitilira apo, ndikusintha kosinthika komwe kumadula mwachangu ndikuboola zinthu zachitsulo ndi chitsulo champhamvu kwambiri komanso mphamvu zamphamvu.

Kuphatikiza apo, ngati munamvapo kuwotcherera kwa laser, m'malo mwatsopano wazowotcherera wamba, mungadziwe kuti ndi njira yabwino. Osati kokha chifukwa cha kusinthasintha kwakukulu, komanso chifukwa cha ubwino wambiri.

Kutengera ndi kuwala kwa laser mtengo, ogwira ntchito amatha kuwotcherera zitsulo popanda chodzaza ndi kuwotcherera. Poyerekeza ndi kuwotcherera kwachikhalidwe kwa argon arc, njira yodziwika kwambiri yowotcherera pakali pano, kuwotcherera kwa fiber laser kumatha kudutsa zinthu zowonekera, zomwe zingamulepheretse kuvulala ndi kukonza kwakutali. Ndipo itha kugwiritsidwa ntchito m'malo ovuta kwambiri, monga kutentha kwambiri, kuzizira kwambiri komanso malo otulutsa ma radio.
