Te whakaiti i tewhānui raina taiaho
He hononga tika te whānui o te rārangi o te taiaho ki te momo taiaho. Ka taea te whakaiti i te whānui o te rārangi taiaho mā te arotau i te hoahoa taiaho me te whakaiti i te awe o te haruru o waho i te mea ka taea. Ko te taahiraa tuatahi ko te whakatau ko tēhea te mea matua, te haruru kuantum, te haruru matarohia rānei, nā te mea ka pā tēnei ki ngā inenga e whai ake nei.
Ina teitei te mana o te kōhao-roto, he iti te ngaronga o te resonator, ā, he roa te wā haere-hoki o te resonator, ko te haruru kuantum o terēseri(ko te nuinga he haruru tukunga ohorere). Tērā pea ka puta te haruru tawhito i te ngoki ā-ringa. Ka taea te whakaiti i ngā rerekētanga mā te whakamahi i tētahi resonator laser poto kiato, engari i ētahi wā i roto i ngā resonator poto ake, ka taea e ngā rerekētanga roa te whakaputa i tētahi pānga kaha ake. Mā te hoahoa ā-ringa whaitake ka taea te whakaiti i te hononga i waenga i te resonator laser me te hihi o waho, me te whakaiti hoki i te pānga nekeneke wera. Tērā anō hoki ngā rerekētanga wera i roto i te reo whakanui, e puta mai ana i ngā rerekētanga o te mana papu.
Mō te pai ake o te mahi haruru, me whakamahi ētahi atu taputapu whakaū kaha, engari he pai ake te whakamahi i ngā tikanga mahi kore mahi i te tuatahi. Ko te whānuitanga o te rēhia totoka auau-kotahi memuka rēserihe maha ngā kilohertz, ā, i ētahi wā he iti iho i te 1KHz. Mā te whakamahi i te tikanga whakapūmau kaha, ka taea te whiwhi i te whānui rārangi he iti iho i te 1KHz. Ko te whānui rārangi o ngā taiaho taiaho kei roto i te awhe MHZ, ā, ka taea hoki te whakaiti ki te KHz, pērā i ngā taiaho taiaho kōhao o waho, inā koa mō ngā taiaho urupare whatu me te kōhao tohutoro tino tika.
He mea tika kia mōhiotia i ētahi wā, hepūtake mārama taiahokāore e hiahiatia hei whakaputa i tētahi whānui mārama whaiti rawa:
1. Ina roa te hononga, ka whakararuraru te pānga hononga (nā te ngoikore o te whakaata pirinoa) i te āhua o te hihi mārama. I roto i ngā whakaaturanga whakaata laser, ka taea e te pānga iraira te whakararuraru i te kounga o te mata whakahoki.
2. Ina tukuna te mārama i roto i ngā muka whatu hohe, kore rānei, ka puta ētahi raruraru i ngā whānui rārangi whaiti nā te marara Brillouin whakaohokia. I tēnei wā, me whakanui ake te whānui rārangi, hei tauira, mā te whakarerekē i te diode taiaho ki te iahiko, mā te whakamahi rānei i tētahi whakarerekē whatu hei whakateretere tere i te auau inamata. Ka whakamahia te whānui rārangi i ētahi atu āhuatanga. Ka whakamahia hoki te whānui rārangi hei whakaahua i te whānui o te pirau whatu.
