Ahureirēseri tino terewāhanga tuarua
Te horapa o te marara me te pāorooro: Te horapa o te whakaroa rōpū
Ko tētahi o ngā wero hangarau tino uaua ka pā ki te whakamahi i ngā taiaho tino tere ko te pupuri i te roanga o ngā pāoro poto rawa e tukuna ana e terēseriHe tino ngāwari ngā pāoro tere rawa ki te whakapōturi i te wā, ka roa ake ai ngā pāoro. Ka kino haere tēnei pānga i te poto haere o te roanga o te pāoro tuatahi. Ahakoa ka taea e ngā taiaho tere rawa te tuku pāoro mō te 50 hēkona te roa, ka taea te whakanui ake i te wā mā te whakamahi i ngā whakaata me ngā karāhe hei tuku i te pāoro ki te wāhi ūnga, mā te tuku noa rānei i te pāoro mā te hau.
Ka inehia tēnei whakapōturitanga wā mā te whakamahi i tētahi inenga e kiia nei ko te marara whakaroa rōpū (GDD), e mōhiotia ana ko te marara tuarua-raupapa. Inaa, kei reira anō ngā kupu marara teitei-raupapa ka pā ki te tohatoha wā o ngā pāoro ultrafart-laser, engari i roto i te mahi, he nui noa te tirotiro i te pānga o te GDD. Ko te GDD he uara e whakawhirinaki ana ki te auau e rite ana ki te matotoru o tētahi rauemi. Ko ngā whatu tuku pēnei i te arotahi, te matapihi, me ngā wāhanga whāinga he uara GDD pai, e tohu ana ka taea e ngā pāoro kua pēhia te hoatu ki ngā whatu tuku he roa ake te roa o te pāoro i ērā e tukuna ana engā pūnaha taiaho. Ka tere ake te horapa o ngā wāhanga he iti ake ngā auau (arā, he roa ake ngā roangaru) i ngā wāhanga he teitei ake ngā auau (arā, he poto ake ngā roangaru). I te haere o te pātere i roto i te maha atu o ngā mea, ka haere tonu te roangaru o te pātere ki te toro haere tonu i roto i te wā. Mō ngā roanga pātere poto ake, ā, nō reira, he whānui ake ngā whānui o te whānuitanga, ka nui ake te whakanui i tēnei pānga, ā, ka hua ake he whakapōturitanga nui o te wā pātere.
Ngā tono taiaho tino tere
tirotiro matawai
Mai i te taenga mai o ngā pūtake taiaho tere rawa, ko te tirotiro irahiko tētahi o ngā wāhi matua o tā rātou whakamahinga. Mā te whakaiti i te roa o te pāorooro ki ngā femtoseconds, ki ngā attoseconds rānei, ka taea te whakatutuki i ngā tukanga hihiri i roto i te ahupūngao, te matū me te koiora i kore e taea te tirotiro i mua. Ko tētahi o ngā tukanga matua ko te nekehanga ngota, ā, kua pai ake te māramatanga pūtaiao o ngā tukanga taketake pēnei i te wiri ngota, te wehenga ngota me te whakawhiti pūngao i roto i ngā pūmua whakaahua.
whakaahua koiora
Ka tautokohia e ngā taiaho tino tere te kaha-tino kaha ngā tukanga kore-raina, ā, ka whakapai ake i te taumira mō te whakaahua koiora, pērā i te karuārai maha-photon. I roto i te pūnaha maha-photon, kia puta ai he tohu kore-raina mai i tētahi reo koiora, i tētahi ūnga rama-ā-rangi rānei, me taupatupatu ngā rama-ā-rangi e rua i te wāhi me te wā. Ka whakapai ake tēnei tikanga kore-raina i te taumira whakaahua mā te whakaiti nui i ngā tohu rama-ā-rangi papamuri e whakararuraru ana i ngā rangahau o ngā tukanga rama-ā-rangi kotahi. Ka whakaaturia te papamuri tohu kua whakangawaritia. Ka ārai hoki te rohe whakaoho iti o te karuārai maha-photon i te paitini whakaahua me te whakaiti i te kino ki te tauira.

Te tukatuka rauemi taiaho
Kua hurihia hoki e ngā pūtake taiaho tere rawa te mahi miihini taiaho me te tukatuka rauemi nā te huarahi ahurei e taunekeneke ai ngā pāoro poto rawa ki ngā rauemi. E ai ki te kōrero i mua ake nei, i te wā e kōrero ana mō te LDT, he tere ake te roa o te pāoro tere rawa i te tauine wā o te horapa wera ki roto i te whatunga o te rauemi. Ka whakaputahia e ngā taiaho tere rawa he rohe iti ake e pāngia ana e te wera i tengā taiaho pāorooro nanohekona, ka hua ake he iti ake ngā ngaronga tapahi me te miihini tika ake. Ka pā anō hoki tēnei mātāpono ki ngā tono hauora, ina āwhina te whakanui ake i te tika o te tapahi ultrafart-reser ki te whakaiti i te kino ki ngā kiko e karapoti ana, ā, ka whakapai ake i te wheako o te tūroro i te wā o te pokanga reser.
Ngā pātere attosecond: te heke mai o ngā taiaho tino tere
I te haere tonu o ngā rangahau ki te whakatairanga i ngā taiaho tere rawa, kei te whakawhanakehia ngā pūtake mārama hou me ngā pūtake mārama kua whakapaitia me ngā roanga poto ake o te pā. Hei whiwhi māramatanga ki ngā tukanga ā-tinana tere ake, he maha ngā kairangahau e arotahi ana ki te whakaputa i ngā pā attosecond – tata ki te 10-18 hēkona i roto i te awhe roangaru ultraviolet tino (XUV). Mā ngā pā attosecond ka taea te whai i te nekehanga irahiko me te whakapai ake i tō tātou māramatanga ki te hanganga hiko me te miihini irahiko. Ahakoa kāore anō kia tino ahu whakamua te whakaurunga o ngā taiaho attosecond XUV ki roto i ngā tukanga ahumahi, ko ngā rangahau me ngā whanaketanga tonu i roto i te mara ka tino panaia tēnei hangarau i waho o te taiwhanga ki roto i te hanga, pērā i te mea kua pā ki te femtosecond me te picosecond.ngā pūtake taiaho.
