Kua noho ngā taiaho (Light Amplification by Stimulated Emission of Radiation) hei hangarau matua i roto i te whanaketanga o te ahumahi hou. Nā tō rātou kaha ki te whakaputa i ngā hihi mārama tino tika, kaha, me te tika, ka whakamahia whānuitia ngā taiaho mō te tapahi, te whakarewa, te tohu, te ine, tae atu ki ngā tukanga hanga hangarau teitei pēnei i te hikohiko iti me ngā taputapu hauora. I roto i ngā momo ahumahi, ehara i te mea ko ngā taiaho anake te whakakapi i ngā tikanga tuku iho engari kei te whakatuwhera hoki i ngā huarahi hou i uaua i mua nā ngā herenga o ngā taputapu miihini. Ka matapakihia e tēnei tuhinga ngā momo whakamahinga o ngā taiaho i roto i te ahumahi, ō rātou painga, me ngā au o te whakamahinga.
1. Ngā mātāpono taketake me ngā take e tino pai ai ngā taiaho i roto i te umanga
Ko te painga o ngā taiaho kei roto i ō rātou āhua honohono (ngā ngaru e hāngai ana), he kotahi te tae (ngā roangaru motuhake), me ngā āhuatanga tino arotahi. Mā te whakamahi i ngā karu arotahi me ngā pūnaha whatu, ka taea te whakaemi i te kaha taiaho ki tētahi pūwāhi iti rawa, ka hua ake he kiato kaha teitei. Nō reira, ka taea e ngā taiaho te whakamahana, te rewa, te mimiti, te whakarerekē rānei i te mata o ngā rauemi i roto i tētahi huarahi whakahaere.
Haunga te tika, ka tukuna hoki e ngā reera he tukanga kore-pa. Ko te tikanga kāore he kaha miihini tika e pā ana ki te mea mahi, pērā i te tapahi ki te maripi, ki te wiri rānei. Ka whakaitihia te kakahu o te taputapu, ka whakaitihia te rerekētanga, ā, ka whakapai ake i te ōritetanga o te hua. Ka ngāwari hoki te whakahaere aunoa i ngā reera mā te CNC (Computer Numerical Control) me ngā karetao ahumahi rānei, e pai ai mō te whakaputa papatipu me te whakaputa ngāwari me ngā hoahoa e huri haere ana.
2. Te tapahi taiaho
Ko te tapahi taiaho tētahi o ngā whakamahinga tino rongonui. Ka whakamahia e tēnei tukanga te pūngao taiaho hei tapahi i ngā rauemi pēnei i te maitai, te maitai kore waikura, te konumohe, te kiriaku, te rakau, te papanga, me ētahi mea whakakotahi. Ka tutuki te tapahi mā te whakarewa, te whakamakuku rānei i te rauemi i te ara tapahi, me te āwhina pinepine e te hau (hei tauira, te hāora, te hauota, te hau kōpeke rānei) hei pupuhi i te rauemi rewa, kua tahuna rānei i waho o te āputa tapahi.
Ko ngā painga o te tapahi laser ko:
