Ngā āhuatanga ahurei o te tino terengā taiaho
Ko te roanga o te pao poto rawa o ngā taiaho tere rawa ka hoatu ki ēnei pūnaha ngā āhuatanga ahurei e wehewehe ana i a rātou mai i ngā taiaho pao roa, ngaru tonu rānei (CW). Hei whakaputa i tētahi pao poto pēnei, me whai whānui te whānuitanga o te whānuitanga. Ko te āhua o te pao me te roanga o te ngaru pokapū ka whakatau i te whānuitanga iti rawa e hiahiatia ana hei whakaputa i ngā pao o tētahi roanga motuhake. I te nuinga o te wā, ka whakaahuahia tēnei whanaungatanga i roto i ngā kupu o te hua whānui-wā (TBP), e ahu mai ana i te mātāpono koretake. Ko te TBP o te pao Gaussian ka hoatuhia e te tātai e whai ake nei: TBPGaussian=ΔτΔν≈0.441
Ko Δτ te roanga o te pāoro, ā, ko Δv te whānui o te auau. Ko te tikanga, e whakaatu ana te whārite he whanaungatanga whakahurihuri i waenga i te whānui o te whānuitanga o te hihi me te roanga o te pāoro, arā, i te hekenga o te roanga o te pāoro, ka piki ake te whānui e hiahiatia ana hei whakaputa i taua pāoro. E whakaatu ana te Pikitia 1 i te whānui iti rawa e hiahiatia ana hei tautoko i ētahi roanga pāoro rerekē.

Ngā wero hangarau o ngā taiaho tino tere
Me whakahaere tika te whānuitanga o te whānuitanga o ngā hihi, te kaha o te tihi, me te roa o te pao poto o ngā taiaho tere-tino i roto i tō pūnaha. He maha ngā wā, ko tētahi o ngā otinga māmā ki ēnei wero ko te putanga whānuitanga o ngā taiaho. Mena kua whakamahia e koe ngā taiaho pao roa ake, ngā taiaho ngaru-tonu rānei i mua, tērā pea kāore e taea e tō taonga o ngā wāhanga whatu te whakaata, te tuku rānei i te whānuitanga katoa o ngā pao tere-tino.
Paepae kino taiaho
He rerekē rawa atu hoki ngā paepae kino taiaho (LDT) o ngā whatu tino tere, ā, he uaua ake ki te whakatere i ngā pūtake taiaho tuku iho. Ina whakaratohia ngā whatu mōngā taiaho pāorooro nanohekona, ko ngā uara LDT kei roto i te 5-10 J/cm2. Mō ngā whatu tino tere, kāore i te tino rangona ngā uara o tēnei rahi, nā te mea he nui ake te tūponotanga o ngā uara LDT ki te <1 J/cm2, tata atu ki te 0.3 J/cm2. Ko te rerekētanga nui o te kaha LDT i raro i ngā roanga rerekē o te pāorooro ko te hua o te tikanga kino o te taiaho i runga i ngā roanga pāorooro. Mō ngā taiaho nanohekona, roa atu rāneingā taiaho pupuhi, ko te tikanga matua e hua ai te kino ko te whakamahana wera. Ko ngā rauemi paninga me te papa o tengā taputapu whatuka mimiti i ngā photon taunga mai, ka whakamahana i a rātou. Ka taea e tēnei te whakapōturi i te whatunga tioata o te rauemi. Ko te whānui wera, te pakaru, te rewa me te taumahatanga whatunga ngā tikanga kino wera noa o ēneingā pūtake taiaho.
Heoi, mō ngā taiaho tere rawa, he tere ake te roa o te pā o te pū i te tauine wā o te whakawhiti wera mai i te taiaho ki te whatunga rauemi, nō reira ehara te pānga wera i te tino take o te kino i puta mai i te taiaho. Engari, ko te mana tihi o te taiaho tere rawa ka huri i te tikanga kino ki ngā tukanga kore-raina pērā i te mimiti maha-photon me te ionization. Koia te take kāore e taea te whakawhāiti noa i te whakatauranga LDT o te pū nanohekona ki te pū tere rawa, nā te mea he rerekē te tikanga ā-tinana o te kino. Nō reira, i raro i ngā āhuatanga whakamahinga ōrite (hei tauira, te roanga ngaru, te roa o te pā, me te tere whakahoki), ko te taputapu whatu me te whakatauranga LDT teitei rawa te taputapu whatu pai rawa atu mō tō tono motuhake. Ko ngā whatu i whakamatautauria i raro i ngā āhuatanga rerekē kāore e tohu ana i te mahi tūturu o ngā whatu ōrite i roto i te pūnaha.
