Te mātotoru o te mana me te mātotoru o te pūngao o te taiaho
Ko te mātotoru he rahinga ā-tinana e tino mōhiotia ana e tātou i roto i tō tātou oranga o ia rā, ko te mātotoru e pā atu ana tātou ko te mātotoru o te rauemi, ko te tātai ko ρ=m/v, arā, ko te mātotoru he ōrite ki te papatipu i wehea e te rōrahi. Engari he rerekē te mātotoru mana me te mātotoru pūngao o te taiaho, i konei ka wehea e te horahanga kaua e te rōrahi. Ko te mana hoki ko tā tātou whakapā atu ki te maha o ngā rahinga ā-tinana, nā te mea ka whakamahia e tātou te hiko i ia rā, ka uru te hiko ki te mana, ko te waeine paerewa ā-ao mō te mana ko W, arā, ko J/s, ko te ōwehenga o te pūngao me te waeine wā, ko te waeine paerewa ā-ao mō te pūngao ko J. Nō reira, ko te mātotoru mana ko te ariā o te whakakotahi i te mana me te mātotoru, engari i konei ko te horahanga hihi o te ira kaua e te rōrahi, ko te mana i wehea e te horahanga ira putanga ko te mātotoru mana, arā, ko te waeine o te mātotoru mana ko W/m2, ā, i roto i temara taiaho, nā te mea he iti rawa te horahanga o te wāhi iraira taiaho, nō reira ko te tikanga ka whakamahia a W/cm2 hei waeine. Ka tangohia te mātotoru pūngao mai i te ariā o te wā, ka whakakotahi i te pūngao me te mātotoru, ā, ko te waeine ko J/cm2. I te nuinga o te wā, ka whakaahuahia ngā taiaho tonu mā te whakamahi i te mātotoru mana, i te wāngā taiaho pupuhie whakaahuatia ana mā te whakamahi i te kiato mana me te kiato pūngao.
Ina mahi te taiaho, ko te kiato mana te tikanga e whakatau ana mēnā kua eke ki te paepae mō te whakangaro, te whakakore rānei, me ētahi atu rauemi mahi. Ko te paepae he ariā e puta pinepine ana i te wā e ako ana i te taunekeneke o ngā taiaho me te matū. Mō te ako i te pāoro poto (ka taea te whakaaro ko te wāhanga us), te pāoro poto rawa (ka taea te whakaaro ko te wāhanga ns), tae atu ki ngā rauemi taunekeneke taiaho tino tere (wāhanga ps me te fs), ko ngā kairangahau tōmua te tikanga o te kiato pūngao. Ko tēnei ariā, i te taumata taunekeneke, e tohu ana i te pūngao e mahi ana ki te ūnga mō ia wāhanga horahanga, i roto i te take o te taiaho o te taumata kotahi, he nui ake te hiranga o tēnei kōrero.
He paepae anō hoki mō te kiato pūngao o te werohanga kotahi-pā. Nā tēnei ka uaua ake te ako i te taunekeneke taiaho-matū. Heoi, kei te huri tonu ngā taputapu whakamātautau o ēnei rā, he maha ngā momo whānui pā, te pūngao kotahi-pā, te auau tāruarua me ētahi atu tawhā kei te huri tonu, ā, me whakaaro anō hoki ki te putanga tuturu o te taiaho i roto i ngā rerekētanga pūngao pā i roto i te take o te kiato pūngao ki te ine, tera pea he tino taratara. I te nuinga o te wā, ka taea te whakaaro whānui ko te kiato pūngao wehea ki te whānui pā ko te kiato mana toharite wā (kia mahara ko te wā, ehara i te wāhi). Heoi, he mārama ko te āhua o te ngaru taiaho tuturu kāore pea i te tapawhā, i te ngaru tapawhā, i te pere, i te Gaussian rānei, ā, ko ētahi ka whakatauhia e ngā āhuatanga o te taiaho tonu, he āhua ake.
Ko te whānui o te pāorooro ka tukuna mā te whānui haurua-teitei e whakaratohia ana e te oscilloscope (te haurua-whānui tihi katoa FWHM), e meinga ai tātou kia tatau i te uara o te mātotoru mana mai i te mātotoru pūngao, he teitei. Ko te haurua teitei me te whānui e tika ana me tatau mā te taupū, te haurua teitei me te whānui. Kāore anō kia uiuitia taipitopito mēnā he paerewa rerekē e tika ana hei mōhio. Mō te mātotoru mana tonu, i te wā e mahi ana i ngā tataunga, he mea pea te whakamahi i te pūngao pāorooro kotahi hei tatau, he pūngao pāorooro kotahi/whānui pāorooro/rohe ira, ko te mana toharite ā-wāhi, kātahi ka whakareatia ki te 2, mō te mana tihi ā-wāhi (ko te tohatoha ā-wāhi ko te tohatoha Gauss he maimoatanga pēnei, kāore e hiahiatia e te potae-runga te mahi pera), kātahi ka whakareatia ki te whakapuakitanga tohatoha radial, Ā, kua oti koe.
