Kulabo kini abangazi ukuthi i-LASER empeleni isifinyezo esimele i-Light Amplification by Stimulated Emission of Radiation. I-laser yasungulwa ngo-1960 yisazi sesayensi saseMelika uTheodore H. Maiman, kodwa kwaze kwaba ngo-1967 lapho udokotela waseHungary nodokotela ohlinzayo uDkt. Andre Mester lapho i-laser yayinenani elikhulu lokwelapha. I-Ruby Laser yayiyidivayisi yokuqala ye-laser eyake yakhiwa.
Esebenza eNyuvesi yaseSemelweiss eBudapest, uDkt. Mester ngephutha wathola ukuthi ukukhanya kwe-ruby laser okuphansi kungakhulisa izinwele kabusha emagundwini. Ngesikhathi sokuhlola lapho ayezama ukuphinda ucwaningo lwangaphambilini olwathola ukuthi ukukhanya okubomvu kunganciphisa amathumba emagundwini, uMester wathola ukuthi izinwele zikhula ngokushesha emagundwini aphathwe kunasemagundwini angelashwanga.
UDkt. Mester uphinde wathola ukuthi ukukhanya kwe-laser ebomvu kungasheshisa inqubo yokuphulukiswa kwamanxeba angaphandle emagundwini. Ngemva kwalokhu kutholakala wasungula i-Laser Research Center e-Semelweiss University, lapho asebenza khona impilo yakhe yonke.
Indodana kaDkt. Andre Mester, u-Adam Mester, yabikwa esihlokweni se-New Scientist ngo-1987, eminyakeni engaba ngu-20 ngemva kokutholakala kukayise, ukuthi wayesebenzisa ama-laser ukwelapha izilonda 'ezingelapheki'. “Uthatha iziguli ezithunyelwe abanye ochwepheshe ababengenakukwazi ukuzenza,” kusho lesi sihloko. Kulaba abangu-1300 abelashwe kuze kube manje, usethole ukuphulukiswa okuphelele ngamaphesenti angu-80 kanye nokuphulukiswa okuyingxenye ngamaphesenti angu-15.” Laba ngabantu abaya kudokotela wabo kodwa abakwazanga ukusizwa. Ngokungazelelwe bavakashela u-Adam Mester, futhi amaphesenti angu-80 abantu aphelele aphulukiswa kusetshenziswa ama-laser abomvu.
Ngokuthakazelisayo, ngenxa yokungaqondi kahle ukuthi ama-laser anikeza kanjani imiphumela yawo emihle, ososayensi abaningi nodokotela ngaleso sikhathi babethi lokhu kungenxa 'yomlingo.' Kodwa namuhla, sesiyazi ukuthi akuwona umlingo; siyazi kahle ukuthi usebenza kanjani.
ENyakatho Melika, ucwaningo lwe-red light aluzange luqale ukusebenza kwaze kwaba cishe ngonyaka ka-2000. Kusukela ngaleso sikhathi, umsebenzi wokushicilela ukhule cishe kakhulu, ikakhulukazi eminyakeni yamuva nje.
