Endre Mester, oo ah dhakhtar reer Hungary ah, ahna dhakhtar qalliin, ayaa lagu amaanay inuu ogaaday saameynta bayoolojiga ee laysarka awoodda yar, kaas oo dhacay dhowr sano ka dib ikhtiraacii laysarka ruby ee 1960-kii iyo ikhtiraacii laysarka helium-neon (HeNe) ee 1961-kii.
Mester wuxuu aasaasay Xarunta Cilmi-baarista Laser-ka ee Jaamacadda Caafimaadka ee Semmelweis ee Budapest sanadkii 1974-kii, wuxuuna halkaas ka sii watay intii noloshiisa ka hartay. Carruurtiisu waxay sii wadeen shaqadiisa waxayna u soo dhoofiyeen Mareykanka.
Sannadkii 1987-kii, shirkadaha iibiya laysarka ayaa sheegay inay daweyn karaan xanuunka, ay dedejin karaan bogsashada dhaawacyada isboortiga, iyo waxyaabo kaloo badan, laakiin xilligaas ma jirin wax caddayn ah oo arrintan ku saabsan.
Mester asal ahaan wuxuu habkan ugu yeeray "biyoolajiyada laysarka", laakiin dhawaan waxaa loo yaqaan "daaweynta laysarka heerka hoose" ama "daaweynta iftiinka cas". Iyadoo diode-yada iftiinka soo saaraya ay la qabsadeen kuwa baranaya habkan, waxaa markaa loo yaqaanay "daaweynta iftiinka heerka hoose", si loo xalliyo jahawareerka ku saabsan macnaha saxda ah ee "heerka hoose", ereyga "sawir-qaadis" ayaa soo baxay.
