Ngā āhuatanga matua o ngā laser

Ko te matuangā āhuatanga o ngā taiaho

Te whakatupuranga ongā taiahoKo te ariā o te "irahiko ohorere me te whakaohooho" i whakatakotoria e Einstein i te tau 1916 te turanga ā-tinana o te ao houpūnaha taiaho. Ka puta pea i te taunekeneke i waenga i ngā photon me ngā ngota e toru ngā momo tukanga whakawhiti: te mimiti whakaohooho, te tukunga ohorere, me te tukunga whakaohooho.

Ko ngā āhuatanga matua o ngā lasers ko:

1. Te ahunga pai: Nā te mea ko te hihi mārama anake e horapa ana i te tuaka o te kōhao whakakoi ka taea te hanga i te wiri me te whakanui tonu, he iti rawa te koki wehewehe o te putanga taiaho mai i te taiaho, ā, he tino pai te ahunga, ka waiho hei puna mārama whakarara pai.

2. Te kanapa teitei: Nā te pai o te ahunga, ka tino kukū te kaha o te taiaho ki te wāhi, ā, ka taea ai e ia te whai i te kaha tino teitei. Ko te kanapa whānui o te rā he tata ki te 100W/cm ². Ko te kaha o te mārama o te taiaho helium-neon me te kaha o te maha o ngā miriwati ka taea te rau ngā wā teitei ake i te kaha o te rā. He taiaho e mahi ana i roto i te pao

Ka taea e te āhua o te mārama te whai i te 107 ki te 1014 ngā wā teitei ake i tō te rā.

3. He pai te kotahi-tae: Nā te mea he rite tonu te auau o ngā photon i whakaputaina e te irahiko whakaoho, ā, he iti noa iho i te kōhao whakapūmau, ko te mārama anake o te roangaru kua whakaritea ka taea te wiri me te whakaputa. Nō reira, he tino pai te kotahi-tae o ngā laser.

4. He pai te ōritetanga: Ko te mārama noa e puta mai ana i te hihi ohorere he mārama kore ōritetanga, engari ko ngā āhuatanga o te mārama e tukuna ana e te hihi whakaohooho ka pai te ōritetanga o ngā reera. Mā ēnei āhuatanga matua e whā ka whakaratohia he tikanga tātaritanga hou me ngā hangarau tautuhi whakaahua mō te rongoā me te koiora.

Ngā tūponotanga o ngā taiaho me ngā mahi haumaru

Ko ngā kino ka pā mai i ngā taiaho ki te tinana tangata ka taea te wehewehe kia rua ngā wāhanga. Ko tētahi momo he kino tika, arā, ko te hihi mārama o ngā taiaho e nui ake ana i te paepae haumaru ka pā kino ki ngā kanohi, ki te kiri, ki te pūnaha io me ngā whekau o roto. Ko tētahi atu wāhanga ko ngā tūponotanga ā-korekore i puta mai i ngā āhuatanga pēnei i te hiko ngaohiko teitei, te haruru, ngā pouaka whakamatao pāmahana iti me ngā pūtake hiko. Nō reira, me mahi ngā mahi haumaru e rite ana: te aroturuki me te whakahaere i te pūnaha taiaho me te taiao mahi, me te tiaki whaiaro hoki.
