Endre Mester, ib tug kws kho mob Hungarian, thiab kws phais neeg, tau txais txiaj ntsig los ntawm kev tshawb pom cov teebmeem ntawm cov lasers fais fab tsawg, uas tau tshwm sim ob peb xyoos tom qab xyoo 1960 tsim cov laser ruby thiab xyoo 1961 tsim cov helium-neon (HeNe) laser.
Xyoo 1974, Mester tau tsim lub Chaw Tshawb Fawb Laser ntawm Semmelweis Medical University hauv Budapest thiab txuas ntxiv ua haujlwm nyob ntawd mus txog thaum kawg ntawm nws lub neej. Nws cov menyuam txuas ntxiv nws txoj haujlwm thiab coj mus rau Tebchaws Meskas.
Los ntawm xyoo 1987 cov tuam txhab muag lasers tau hais tias lawv tuaj yeem kho qhov mob, ua kom sai dua ntawm kev kho mob kis las, thiab ntau ntxiv, tab sis tsis muaj pov thawj me ntsis rau qhov no thaum lub sijhawm ntawd.
Mester thawj zaug hu txoj kev no ua "laser biostimulation", tab sis nws sai sai no hu ua "low-level laser therapy" lossis "red light therapy". Nrog cov light-emitting diodes uas cov neeg kawm txoj hauv kev no tau hloov kho, nws tom qab ntawd hu ua "low-level light therapy", thiab los daws qhov kev tsis meej pem txog lub ntsiab lus ntawm "low level", lo lus "photobiomodulation" tau tshwm sim.
