Ngā momo taiaho ka taea te whakarerekē

Ngā momo orēseri ka taea te whakarerekē

Ko te whakamahinga o ngā taiaho ka taea te whakarerekē ka taea te wehewehe ki ngā wāhanga matua e rua: ko te tuatahi, ina kore e taea e ngā taiaho roangaru kotahi-raina, maha-raina rānei te whakarato i te roangaru motuhake e hiahiatia ana; ko tētahi atu wāhanga ko ngā āhuatanga kei reira terēseriMe aro tonu te aro ki te roanga ngaru i ngā wā whakamātautau, pērā i te tirotiro ira me ngā whakamātautau kimi papu.

He maha ngā momo taiaho ka taea te whakarerekē ka taea te whakaputa i ngā putanga ngaru tonu (CW), nanohekona, pikohekona, femtohekona rānei. Ka whakatauhia ōna āhuatanga putanga e te reo whakanui taiaho e whakamahia ana. Ko te whakaritenga taketake mō ngā taiaho ka taea te whakarerekē ko te taea e rātou te tuku taiaho ki runga i te whānuitanga o ngā roangaru. Ka taea te whakamahi i ngā wāhanga whatu motuhake hei tīpako i ngā roangaru motuhake, i ngā roopu roangaru rānei mai i ngā roopu tukunga ongā taiaho ka taea te whakarerekēI konei ka whakamōhio atu mātou ki a koe i ētahi taiaho whakarerekē noa

Reiti ngaru tū CW ka taea te whakarerekē

I roto i te ariā, ko teTaiaho CW ka taea te whakarerekēKo te hoahoa taiaho māmā rawa atu tēnei. Kei roto i tēnei taiaho he whakaata whakaata-teitei, he reo whakanui me te whakaata hononga putanga (tirohia te Pikitia 1), ā, ka taea e ia te whakarato putanga CW mā te whakamahi i ngā momo reo whakanui taiaho. Hei whakatutuki i te āheinga whakarerekē, me whiriwhiri he reo whakanui ka taea te kapi i te awhe roangaru ūnga.

2. Mowhiti rēhia CW ka taea te whakarerekē

Kua roa te whakamahinga o ngā taiaho mowhiti hei whakatutuki i te putanga CW ka taea te whakarerekē mā te aratau roa kotahi, me te whānuitanga o te hihi i roto i te awhe kilohertz. Pērā i ngā taiaho ngaru tū, ka taea hoki e ngā taiaho mowhiti ka taea te whakarerekē te whakamahi i ngā tae me te hapaira titanium hei pāpāho whakanui. Ka taea e ngā tae te whakarato i te whānui rārangi tino whaiti o raro iho i te 100 kHz, ko te hapaira titanium ia e tuku ana i te whānui rārangi o raro iho i te 30 kHz. Ko te awhe whakarerekē o te taiaho tae he 550 ki te 760 nm, ā, ko te taiaho hapaira titanium he 680 ki te 1035 nm. Ka taea te whakanekeneke i te auau o ngā putanga o ngā momo taiaho e rua ki te roopu UV.

3. Reera āhua-tonu kua raka-aratau

Mō ngā tono maha, he mea nui ake te tautuhi tika i ngā āhuatanga wā o te putanga taiaho i te tautuhi tika i te pūngao. Inaa, ko te whakatutuki i ngā pāoro whatu poto me whai whirihoranga kōhao me ngā momo roa maha e tangi ana i te wā kotahi. Ina he whanaungatanga ā-wāhanga pumau kei roto i te kōhao taiaho o ēnei momo roa hurihuri, ka maukati-aratau te taiaho. Mā tēnei ka taea e te pāoro kotahi te wiri i roto i te kōhao, me tōna wā e tautuhia ana e te roa o te kōhao taiaho. Ka taea te whakatutuki i te maukati-aratau hohe mā te whakamahi i tētahikaiwhakarerekētanga oro-whatu(AOM), te raka aratau kore mahi rānei, ka taea te whakatutuki mā te arotahi Kerr.

4. Taiaho ytterbium tino tere

Ahakoa he whānui te whakamahinga o ngā taiaho hapaira titanium, ko ētahi whakamātautau whakaahua koiora e hiahia ana ki ngā roangaru roa ake. Ko te tukanga mimiti e rua-ira ka whakaohokia e ngā iira he roangaru 900 nm. Nā te mea he iti ake te marara o ngā roangaru roa ake, ka taea e ngā roangaru whakaoho roa ake te akiaki i ngā whakamātautau koiora e hiahia ana ki te hohonutanga whakaahua hohonu ake.

I ēnei rā, kua whakamahia ngā taiaho ka taea te whakarerekē i roto i ngā mara nui maha, mai i te rangahau pūtaiao taketake ki te hanga taiaho me ngā pūtaiao ora me te hauora. He whānui rawa te whānuitanga o ngā hangarau e wātea ana i tēnei wā, mai i ngā pūnaha whakarerekē CW māmā, ko tōna whānuitanga raina whaiti ka taea te whakamahi mō te tirotiro matawai teitei, te hopu ngota me te ngota, me ngā whakamātautau whatu matū, e whakarato ana i ngā mōhiohio matua mō ngā kairangahau o ēnei rā. Ko ngā kaihanga taiaho o ēnei rā e tuku ana i ngā otinga kotahi-mutu, e whakarato ana i te putanga taiaho e horapa ana i te 300 nm i roto i te whānuitanga pūngao nanojoule. Ko ngā pūnaha uaua ake e horapa ana i te whānuitanga matawai whānui whakamiharo o te 200 ki te 20,000 nm i roto i ngā whānuitanga pūngao microjoule me millijoule.
