Whakauruhiangā taiaho pāorooro muka
Ko ngā taiaho muka-pāhekohekongā taputapu taiahoe whakamahi ana i ngā muka kua whakaranua ki ngā katote whenua onge (pērā i te ytterbium, te erbium, te thulium, me ētahi atu) hei reo whakanui. Kei roto i ēnei he reo whakanui, he kōhao whatu whakakoi, me te pūtake papu. Ko tana hangarau whakaputa pao he hangarau whakawhiti-Q (taumata nanohekona), he raka aratau hohe (taumata picohekona), he raka aratau kore mahi (taumata femtohekona), me te hangarau whakanui mana oscillation matua (MOPA).
Ko ngā tono ahumahi e kapi ana i te tapahi whakarewa, te whakarewa, te horoi laser me te tapahi TAB pākahiko lithium i roto i te mara pūngao hou, me te mana putanga maha-aratau e eke ana ki te taumata tekau-mano-watt. I roto i te mara o te lidar, ka whakamahia ngā laser pulsed 1550nm, me ō rātou kaha pulsed teitei me ngā āhuatanga haumaru-kanohi, i roto i ngā pūnaha radar whānui me ngā pūnaha radar e mau ana i ngā waka.
Ko ngā momo hua matua ko te momo Q-switched, te momo MOPA me te muka mana-teitei.ngā taiaho pupuhiKāwai:
1. Reiti muka whakawhiti-Q: Ko te kaupapa o te whakawhiti-Q he tāpiri i tētahi taputapu ka taea te whakarite i te ngaronga ki roto i te reiti. I te nuinga o ngā wā, he nui te ngaronga o te reiti, ā, tata kore he putanga mārama. I roto i tētahi wā poto rawa, mā te whakaiti i te ngaronga o te taputapu ka taea e te reiti te whakaputa i tētahi pāoro poto tino kaha. Ka taea te whakatutuki i ngā reiti muka whakawhiti-Q mā te kaha, mā te kore mahi rānei. Ko te hangarau kaha ko te tāpiri i tētahi whakarerekētanga kaha ki roto i te kōhao hei whakahaere i te ngaronga o te reiti. Ka whakamahia e ngā tikanga kore mahi ngā mimiti kua kōtui, ētahi atu pānga kore-raina rānei pērā i te marara Raman whakaoho me te marara Brillouin whakaoho hei hanga i ngā tikanga whakarerekētanga-Q. Ko ngā pāoro e whakaputaina ana e ngā tikanga whakawhiti-Q kei te taumata nanohekona. Mena ka whakaputaina he pāoro poto ake, ka taea te whakatutuki mā te tikanga maukati-aratau.
2. Taiaho muka raka-aratau: Ka taea e ia te whakaputa i ngā pāoro poto rawa mā te raka-aratau hohe, mā te raka-aratau kore rānei. Nā te wā urupare o te modulator, ko te whānui o te pāoro i hangaia e te raka-aratau hohe kei te taumata pikohekona. Ka whakamahia e te raka-aratau kore hohe ngā taputapu raka-aratau kore hohe, he poto rawa te wā urupare, ā, ka taea te whakaputa pāoro i te tauine femtohekona.
Anei tētahi kupu whakataki poto ki te mātāpono o te raka pokepokea ai.
He maha ngā momo āhua roa i roto i te kōhao whakapūmau taiaho. Mō te kōhao porowhita, ko te auau o ngā momo āhua roa he rite ki te /CCL, ko C te tere o te mārama, ā, ko CL te roa o te ara whatu o te mārama tohu e haere ana i roto i te kōhao. I te nuinga o te wā, he nui te whānui o te whiwhinga o ngā taiaho muka, ā, he maha ngā momo āhua roa e mahi tahi ana. Ko te tapeke o ngā momo ka taea e te taiaho te whakauru ka whakawhirinaki ki te wā aratau roa ∆ν me te whānui o te whiwhinga o te reo whiwhinga. Ko te iti o te wā aratau roa, ko te nui ake o te whānui whiwhinga o te reo, ā, ko te nui ake o ngā momo āhua roa ka taea te tautoko. I tetahi atu taha, ko te iti iho.
3. Taiaho Āhua-tonu (taiaho QCW): He momo mahi motuhake i waenga i ngā taiaho ngaru tonu (CW) me ngā taiaho pāorooro. Ka tutuki i a ia te putanga mana tere teitei mā roto i ngā pāorooro roa ā-wā (te nuinga o te huringa mahi ≤1%) me te pupuri tonu i te mana toharite iti. Ka whakakotahi i te pumau o ngā taiaho tonu me te painga mana tihi o ngā taiaho pāorooro.
Mātāpono hangarau: Ka utaina e ngā taiaho QCW ngā kōwae whakarerekētanga i roto i te tonurēserihe ara iahiko hei tapahi i ngā taiaho tonu ki ngā raupapatanga pātere huringa mahi teitei, kia taea ai te whakawhiti ngāwari i waenga i ngā aratau tonu me ngā aratau pātere. Ko tōna āhuatanga matua ko te tikanga "pahū poto, whakamatao roa". Ka whakaitihia e te whakamatao i roto i te āputa pātere te kohikohi wera me te whakaiti i te mōrearea o te whakarerekētanga wera o te rauemi.
Ngā Painga me ngā Āhuatanga: Whakaurunga Aratau-rua: Ka whakakotahi i te mana teitei o te aratau pā (tae atu ki te 10 ngā wā o te mana toharite o te aratau tonu) me te tino whai huatanga me te pumau o te aratau tonu.
He iti te whakamahinga pūngao: He pai te whai huatanga o te hurihanga hiko-whatu, ā, he iti te utu whakamahinga mō te wā roa.
Kounga hihi: Mā te kounga hihi teitei o ngā taiaho muka ka tautoko i te miihini moroiti tika.
