Ka whakatauhia e te taiaho taraiwa te rohe o runga o tetaiaho attosecondpūtake mārama
I tēnei wā,ngā taiaho pāhekoheko attosecondka puta te nuinga mā te whakaputanga haurore teitei (HHG) e peia ana e ngā mara kaha. Ko te uho o tō rātou whakaputanga ka taea te mārama ko ngā irahiko e whakakoitia ana, e whakatereteretia ana, e whakakotahitia ana hei tuku i te pūngao, ā, ka tukuna he pāoro XUV attosecond.
Nō reira, he tino tairongo te putanga o ngā pātere attosecond ki te whānui o te pātere, te kaha, te roanga ngaru, me te auau auau o te taiaho taraiwa: he pai ake ngā whānui pātere poto ki te wehe i ngā pātere attosecond, ka whakapai ake te kaha teitei i te ionization me te whai huatanga, ka whakanui ake ngā roanga ngaru roa i te kaha tapahi engari ka whakaiti nui i te whai huatanga o te tahuritanga, ā, ka whakapai ake ngā auau auau teitei i te ōwehenga tohu-ki-haruru engari ka whakawhāitihia e te kaha pātere kotahi.
He rerekē ngā tono e aro ana ki ngā tohu matua rerekē o ngā taiaho attosecond, nō reira e rite ana ki ngā kōwhiringa hoahoa o ngā momo taraiwa rerekē.ngā pūtake taiaho.
Mō ngā tono pēnei i te rangahau hihiri tino tere me te karu hikohiko, ko te wehenga pumau o ngā pātere attosecond (IAP) me whai pātere taraiwa pātere poto me te whakahaere pai o te wāhanga takai kawe (CEP) kia tutuki ai te whakahaere whai hua o te kuiti wā me te āhua ngaru;
Mō ngā whakamātautau pēnei i te tirotiro irahiko papu-whakamātautau me te whakakoitanga maha-photon, ka āwhina te irahiko attosecond pūngao-teitei, te irahiko attosecond rere-teitei rānei ki te whakapai ake i te pai o te whakaoho/ngoikoretanga, e tutukihia ana i raro i te pūngao taraiwa teitei ake me ngā tikanga mana toharite teitei ake mā te HHG, ā, me pupuri tonu te taurite ā-wāhanga me te kounga hihi e whakaaetia ana i raro i ngā tikanga whakakoitanga teitei;
Hei whakaputa i te irahiko attosecond i roto i te matapihi hihi-X (he mea nui tēnei mō te whakaahua ōrite me te tirotiro mimiti hihi-X kua whakatauhia i te wā), ka whakamahia te taraiwa roa-ngaru waenga-whero hei whakanui ake i te pūngao tapahi harmonic me te whiwhi i te kapinga pūngao photon teitei ake;
I roto i ngā inenga e aro ana ki te tika o te tatauranga, pērā i te tatau me te ine irahiko whakaahua, ka taea e ngā auau tāruarua teitei ake te whakapai ake i te ōwehenga tohu-ki-haruru me te whai huatanga o te kohikohi raraunga, i te mea ka āwhina te utu/pūngao kotahi-pāhekoheko iti ki te whakaiti i te herenga o ngā pānga utu ā-wāhi ki te taumira irahiko pūngao.
Ko te hononga i waenga i ngā tawhā taiaho taraiwa, ngā āhuatanga taiaho pāhekoheko attosecond, me ngā whakaritenga tono e whakaaturia ana i te Pikitia 1. I te nuinga, ko ngā tono o ngā tono e akiaki tonu ana i te whakapainga ake o ngā tawhā taiaho pāhekoheko attosecond, ā, nā reira ka akiaki i te whanaketanga tonu o te hoahoanga me ngā hangarau matua orēseri tino terengā pūnaha.
