He aha te rēseri?
I roto i te poto, ko te rēseri te mārama e puta mai ana i te whakaoho o te matū. Ā, he maha ngā mahi ka taea e tātou te mahi mā te whakamahi i te rēseri.
I roto i a Wikipedia, A rēserihe taputapu e tuku ana i te mārama mā te tukanga whakanui whatu i runga i te tukunga whakaohooho o te irahiko hikohiko. Ko te kupu "reera" he kupu whakarāpopoto mō te "whakanui mārama mā te tukunga whakaohooho o te irahiko". I hangaia te reera tuatahi i te tau 1960 e Theodore H. Maiman i Hughes Research Laboratories, i runga i ngā mahi ariā a Charles Hard Townes rāua ko Arthur Leonard Schawlow.
He rerekē te taiaho i ētahi atu pūtake mārama nā te mea ka tukuna e ia te mārama e ōrite ana. Mā te ōritetanga ā-wāhi ka taea te arotahi i te taiaho ki tētahi wāhi piri, ka taea ai ngā tono pēnei i te tapahi taiaho me te tuhi whakaahua. Mā te ōritetanga ā-wāhi ka taea hoki e te hihi taiaho te noho whaiti i runga i ngā tawhiti roa (whakakorikori), ka taea ai ngā tono pēnei i ngā tohu taiaho me te lidar. Ka taea hoki e ngā taiaho te ōritetanga ā-wā teitei, ka taea ai e rātou te tuku mārama me te whānuitanga tino whaiti. Waihoki, ka taea te whakamahi i te ōritetanga ā-wā hei whakaputa i ngā pāorooro poto rawa o te mārama me te whānuitanga whānui engari he poto te roanga o te wā tae atu ki te femtosecond.
E whakamahia ana ngā taiaho i roto i ngā puku kōpae whatu, ngā pūreretā taiaho, ngā matawai waehere pae, ngā taputapu raupapatanga ira, te muka-whatu, te hanga maramara haurua-whakahaere (whakaahua-tuhi), me te whakawhitiwhiti whatu mokowā-kore, te pokanga taiaho, me ngā maimoatanga kiri, ngā rauemi tapahi me te whakarewa, ngā taputapu hōia me ngā pirihimana mō te tohu i ngā ūnga me te ine i te whānuitanga me te tere, me ngā whakaaturanga rama taiaho mō te whakangahau.
Whai muri i te whanaketanga roa o te hangarau taiaho, ka taea te whakamahi i te taiaho i roto i ngā momo ahumahi rerekē, ā, ko tētahi o ngā whakamahinga tino nui mō te tapahi i ngā ahumahi, ahakoa te whakarewa, te kore-whakarewa rānei, ka whakahoutia e te mīhini tapahi taiaho te tikanga tapahi tuku iho, ka whakapai ake i te pai o te whakaputa mō ngā ahumahi hua, pērā i te kākahu, te whatu, te whāriki, te rakau, te kiriaku, te pānuitanga, te mahi whakarewa, te motuka, ngā taputapu whakapakari tinana me ngā ahumahi tāonga.
Ko te taiaho tētahi o ngā taputapu tapahi pai rawa atu nā te mea he tino tika, he tere hoki ōna āhuatanga tapahi.
