E mōhio ana koe ki ngā rerekētanga i waenga i ngā taiaho nanohekona, picohekona me femtohekona?

Kua tere te whanaketanga o te hangarau taiaho i ngā tekau tau kua pahure ake nei. Mai i te taiaho nanohekona ki te taiaho pikohekona ki te taiaho femtohekona, kua āta whakamahia i roto i ngā mahi hanga ahumahi, e whakarato ana i ngā otinga mō ngā āhuatanga katoa o te ao. Engari e hia te nui o tō mōhiotanga mō ēnei momo taiaho e toru? Kia rapu tahi tātou:

Ngā Whakamāramatanga o ngā Taiaho Nanohekona, Picohekona, me Femtohekona

I te mutunga o te tekau tau atu i 1990, i whakaurua tuatahitia te taiaho nanohekona ki te ao ahumahi hei taiaho totoka-whakapūpū-diode (DPSS). Heoi, he iti te mana whakaputa o ngā taiaho tuatahi pērā, he torutoru watts te rahi, ā, he 355nm te roanga ngaru. I roto i te wā, kua pakeke te mākete mō ngā taiaho nanohekona, ā, ko te nuinga o ngā taiaho he roanga pātī i roto i ngā tekau ki ngā rau o ngā nanohekona.

Ko te taiaho pikohekona he taiaho whānui-poto rawa e tuku ana i ngā taiaho taumata-pikohekona. Ka tukuna e ēnei taiaho he whānui-poto rawa, he auau tāruarua ka taea te whakarite, he kaha taiaho teitei, ā, he pai mō ngā tono i roto i te rongoā koiora, te oscillation tawhā whatu, me te whakaahua moroiti koiora. I roto i ngā pūnaha whakaahua me te tātari koiora hou, kua piki haere te hiranga o ngā taiaho pikohekona hei taputapu.

Ko te taiaho femtosecond he taiaho pao poto rawa atu me te kaha tino teitei, ka tatauhia i roto i ngā femtosecond. Nā tēnei hangarau matatau kua whakaratohia ki te tangata ngā āheinga whakamātautau hou kāore i kitea i mua, ā, he whānui hoki ngā tono. He tino painga te whakamahinga o te taiaho femtosecond tino kaha, pao poto mō ngā kaupapa kimi mō ngā tauhohenga matū maha, tae atu ki te wehenga hononga, te hanganga hononga hou, te whakawhiti pūmua me te irahiko, te isomerization pūhui, te wehenga ngota ngota, te tere, te koki, me te tohatoha āhua o ngā takawaenga tauhohenga me ngā hua whakamutunga, ngā tauhohenga matū e puta ana i roto i ngā otinga me te pānga o ngā whakarewa, tae atu ki te awe o te wiri ngota me te hurihanga ki ngā tauhohenga matū.

Ngā Wāhanga Tahuri Wā mō ngā Nanohekona, ngā Pikohekona, me ngā Femtohekona

1ns (nanohekona) = 0.0000000001 hēkona = 10-9 hēkona

1ps (pikohekona) = 0.0000000000001 hēkona = 10-12 hēkona

1fs (femtohekona) = 0.0000000000000001 hēkona = 10-15 hēkona

Ko ngā taputapu tukatuka taiaho nanohekona, pikohekona, me te femtohekona e kitea whānuitia ana i te mākete, ka tapaina i runga i te wā. Ko ētahi atu āhuatanga, pērā i te kaha o te pā kotahi, te whānui o te pā, te auau o te pā, me te kaha tihi o te pā, he mea nui anō hoki ki te whiriwhiri i ngā taputapu e tika ana mō te tukatuka i ngā rauemi rerekē. Ko te poto o te wā, ko te iti ake o te pānga ki te mata o te rauemi, ka hua ake he pānga tukatuka pai ake.

Ngā Whakamahinga Hauora o ngā Taiaho Picosecond, Femtosecond, me Nanosecond

Ka whakamahanahia, ka whakangaromia hoki e ngā taiaho nanosecond te melanin i roto i te kiri, kātahi ka tangohia atu i te tinana e ngā pūtau, ka memeha haere ngā whara kua whakakōkīhia. He tikanga tēnei e whakamahia whānuitia ana mō te rongoā i ngā mate whakakōkīhia. Ka tere te mahi a ngā taiaho picosecond, ka pakaru ngā matūriki melanin me te kore e kino te kiri e karapoti ana. He pai te rongoā a tēnei tikanga i ngā mate whakakōkīhia pērā i te nevus o Ota me te nevus parauri cyan. Ka mahi te taiaho femtosecond i roto i te āhua o ngā pāorooro, ka taea te tuku i te mana nui i roto i te wā poto, he pai mō te rongoā i te myopia.

Pūnaha Whakamatao mō ngā Taiaho Picosecond, Femtosecond, me Nanosecond

Ahakoa te nanohekona, te picohekona, te femtohekona rānei o te taiaho, he mea tika kia whakarite kia mahi noa te pane taiaho, kia honoa hoki ngā taputapu ki tētahi whakamatao laser . Ko te tika ake o ngā taputapu taiaho, ko te tika ake o te whakahaere pāmahana. TEYU he pumau te pāmahana o te pouaka whakamatao taiaho tino tere o te ±0.1°C, ā, he tere te whakamatao, e whakarite ana kia mahi te taiaho i te pāmahana pumau, ā, he pumau te putanga hihi, ā, ka whakapai ake i te roa o te ora o te taiaho.TEYU ngā whakamatao laser tino tere he pai mō ēnei momo taputapu taiaho e toru.
