No ʻoukou ka poʻe i ʻike ʻole, ʻo LASER kahi huaʻōlelo pōkole e kū nei no ka Light Amplification by Stimulated Emission of Radiation. Ua hana ʻia ka laser i ka makahiki 1960 e ka mea loea ʻAmelika ʻo Theodore H. Maiman, akā ʻaʻole a hiki i ka makahiki 1967 i loaʻa ai i ke kauka Hungarian a me ke kauka ʻokiʻoki ʻo Dr. Andre Mester ka waiwai lapaʻau koʻikoʻi o ka laser. ʻO ka Ruby Laser ka mea hana laser mua loa i kūkulu ʻia.
I kāna hana ʻana ma ke Kulanui ʻo Semelweiss ma Budapest, ua ʻike hewa ʻo Kauka Mester e hiki i ke kukui laser ruby haʻahaʻa ke ulu hou i ka lauoho i loko o nā ʻiole. I ka wā o kahi hoʻokolohua āna e hoʻāʻo nei e hana hou i kahi noiʻi mua i ʻike ʻia hiki i ke kukui ʻulaʻula ke hoʻēmi i nā puʻupuʻu i loko o nā ʻiole, ua ʻike ʻo Mester e ulu wikiwiki ana ka lauoho ma nā ʻiole i mālama ʻia ma mua o nā ʻiole i mālama ʻole ʻia.
Ua ʻike pū ʻo Kauka Mester e hiki i ke kukui laser ʻulaʻula ke hoʻolalelale i ke kaʻina hana ho'ōla o nā ʻeha ma luna o nā ʻiole. Ma hope o kēia ʻike ʻana, ua hoʻokumu ʻo ia i ke Kikowaena Noiʻi Laser ma ke Kulanui ʻo Semelweiss, kahi āna i hana ai no ke koena o kona ola.
Ua hōʻike ʻia ke keiki a Kauka Andre Mester ʻo Adam Mester ma kahi ʻatikala na New Scientist i ka makahiki 1987, ma kahi o 20 mau makahiki ma hope o ka ʻike ʻana o kona makuakāne, ua hoʻohana ʻo ia i nā lasers e mālama i nā ʻeha 'hiki ʻole ke ho'ōla ʻia'. "Lawe ʻo ia i nā maʻi i kuhikuhi ʻia e nā loea ʻē aʻe i hiki ʻole ke hana hou aku no lākou," wahi a ka ʻatikala. No nā 1300 i mālama ʻia a hiki i kēia manawa, ua hoʻokō ʻo ia i ka ho'ōla piha ʻana ma 80 pakeneka a me ka ho'ōla hapa ʻana ma 15 pakeneka. "ʻO kēia ka poʻe i hele i kā lākou kauka a ʻaʻole hiki ke kōkua ʻia. I ka manawa koke, kipa lākou iā Adam Mester, a ua ho'ōla ʻia he 80 pakeneka o ka poʻe me ka hoʻohana ʻana i nā lasers ʻulaʻula.
ʻO ka mea hoihoi, ma muli o ka nele o ka hoʻomaopopo ʻana i ke ʻano o ka hāʻawi ʻana o nā lasers i ko lākou mau hopena maikaʻi, ua manaʻo ka nui o nā kānaka ʻepekema a me nā kauka i kēlā manawa he 'kilokilo.' Akā i kēia lā, ua ʻike mākou ʻaʻole ia he kilokilo; ua ʻike pono mākou pehea e hana ai.
Ma ʻAmelika ʻĀkau, ʻaʻole i hoʻomaka ka noiʻi ʻana i ke kukui ʻulaʻula a hiki i ka makahiki 2000. Mai ia manawa, ua ulu nui ka hana hoʻopuka ʻana, ʻoi aku hoʻi i nā makahiki i hala iho nei.
