Ko Endre Mester, he rata, he taote pokanga nō Hungary, e kiia ana ko ia te tangata i kitea ai ngā pānga koiora o ngā taiaho iti-mana, i puta i ētahi tau i muri i te hanganga o te taiaho rupi i te tau 1960 me te hanganga o te taiaho helium-neon (HeNe) i te tau 1961.
I whakatūria e Mester te Pokapū Rangahau Taiaho i te Whare Wānanga Hauora o Semmelweis i Budapest i te tau 1974, ā, i haere tonu tana mahi ki reira mō te toenga o tōna oranga. I haere tonu āna tamariki ki tana mahi, ā, i kawemai ki te Hononga o Amerika.
Nō te tau 1987, i kī ngā kamupene e hoko ana i ngā taiaho ka taea e rātou te rongoā i te mamae, te tere ake te whakaora i ngā whara hākinakina, me te maha atu, engari he iti noa ngā taunakitanga mō tēnei i taua wā.
I te tuatahi i tapaina e Mester tēnei huarahi ko te "whakaohooraora laser", engari i muri tata mai ka mōhiotia ko te "whakaoraora laser taumata-iti" ko te "whakaoraora rama whero" rānei. Nā te whakamahi a te hunga e ako ana i tēnei huarahi i ngā rama-whakaputa rama, ka mōhiotia ko te "whakaoraora rama taumata-iti", ā, hei whakatau i te pōhēhētanga mō te tikanga tuturu o te "taumata-iti", ka puta te kupu "whakaahua-koiora-whakarerekētanga".
