Kwa inu omwe simukudziwa kuti LASER kwenikweni ndi chidule cha mawu oti Light Amplification by Stimulated Emission of Radiation. Laser iyi idapangidwa mu 1960 ndi katswiri wa sayansi ya zaku America Theodore H. Maiman, koma mpaka mu 1967 dokotala wa ku Hungary komanso dokotala wa opaleshoni Dr. Andre Mester ndiye adapeza kuti laser iyi inali ndi phindu lalikulu pochiritsa. Ruby Laser inali chipangizo choyamba cha laser chomwe chinapangidwapo.
Pogwira ntchito ku Semelweiss University ku Budapest, Dr. Mester mwangozi adapeza kuti kuwala kochepa kwa ruby laser kumatha kumeranso tsitsi m'makoswe. Pa kafukufuku yemwe anali kuyesa kubwereza kafukufuku wakale yemwe adapeza kuti kuwala kofiira kumatha kuchepetsa zotupa m'makoswe, Mester adapeza kuti tsitsi limameranso mwachangu pa makoswe omwe adalandira chithandizo kuposa pa makoswe omwe sanalandire chithandizo.
Dokotala Mester adapezanso kuti kuwala kofiira kwa laser kumatha kufulumizitsa njira yochiritsira mabala osawoneka bwino m'makoswe. Pambuyo pa izi, adakhazikitsa The Laser Research Center ku Semelweiss University, komwe adagwira ntchito moyo wake wonse.
Mwana wa Dr. Andre Mester, Adam Mester, ananenedwa m'nkhani yolembedwa ndi New Scientist mu 1987, patatha zaka 20 kuchokera pamene abambo ake anapeza, kuti ankagwiritsa ntchito laser pochiza zilonda 'zosachiritsika'. "Amatenga odwala omwe atumizidwa ndi akatswiri ena omwe sakanatha kuwachitira china chilichonse," nkhaniyo ikutero. Mwa anthu 1300 omwe adachiritsidwa mpaka pano, wachira kwathunthu mu 80 peresenti ndipo wachira pang'ono mu 15 peresenti." Awa ndi anthu omwe adapita kwa dokotala wawo ndipo sanathe kuthandizidwa. Mwadzidzidzi adapita kwa Adam Mester, ndipo anthu 80 peresenti adachiritsidwa pogwiritsa ntchito laser yofiira.
Chochititsa chidwi n'chakuti, chifukwa chosamvetsetsa momwe laser imaperekera phindu lake, asayansi ambiri ndi madokotala panthawiyo ankanena kuti izi zimachitika chifukwa cha 'matsenga.' Koma masiku ano, tsopano tikudziwa kuti si matsenga; tikudziwa bwino momwe amagwirira ntchito.
Ku North America, kafukufuku wa kuwala kofiira sanayambe kugwira ntchito mpaka chaka cha 2000. Kuyambira pamenepo, ntchito yofalitsa mabuku yakula kwambiri, makamaka m'zaka zaposachedwapa.
