Ko te momo hou opūoko whakaahuaka kitea ngā tohu mārama ngoikore i roto i te roopu 2μm
I roto i ngā mara hou o te rangahau pūtaiao me ngā tono ahumahi, ko te hopu me te tātari tika i ngā tohu mārama ngoikore te mea nui ki te akiaki i te auahatanga hangarau. Ina koa i roto i te roopu waenga-infrared 2-micron (μm), ko te mimiti o ngā tapumati o ngā ngota hau, ngā āhuatanga pā o ngā laser hou, me ngā mōhiohio hohonu o ngā kiko koiora kei roto katoa i tēnei tohu whatu ngoikore engari he nui ngā mōhiohio. Heoi, ko te uaua ki te hopu i te tohu whatu ngoikore, te pehi i te pokanoa taiao, me te uaua o te whakaurunga pūnaha he arai huna tonu i roto i ngā tono rangahau pūtaiao me te hangarau.
I tēnei rā, ka kawea atu e mātou tētahi hua e tutuki ana i ngā whakaritenga o tēnei tono, ko te pūoko whakaahua kitenga mārama anarau momo R-PR-1G 2μm, e whakatapua ana hei "kaikorero" i roto i te mara o te kitenga tohu mārama waenga-whero.
Ko te R-PR-2μmkōwae kimi whakaahuahe mea auaha te whakauru i tētahi tere-teitei kua whakareihiaPūoko whakaahua InGaAsme te whakakaha haruru iti, he rite ki te "tino pūoro" i hangaia mō te ine whatu tika. Ko tana mahi tino pai e whakaatuhia ana i roto i te whānuitanga urupare whatu whānui o te 900-2300nm, ka taea te hipoki i ngā roopu waenga-infrared matua. Ahakoa ko te mimiti āhuatanga o ngā ngota wai i te rangi, ko ngā roangaru ahurei rānei e whakaputaina ana e ngā taiaho muka TM-doped me te Ho, ka taea katoa te hopu tika.
Ehara i te mea koinā anake, he rongonui te waeine whakaahua-whakaahua R-PR-2μm mō tōna kaha nui, tōna tairongo teitei me tōna papatahi pai o te kaha. Ahakoa ngā pāorooro waenga-infrared tino ngoikore o te taumata picosecond ka taea te tautuhi mārama māna, e whakarite ana i te tuku tohu kore-ngaro. I taua wā, ko tōna āhuatanga iti-haruru ka pehi i te pokanoa papamuri, ka whakarato i ngā kairangahau ki ngā raraunga mata parakore me te pono ake. He hanganga kiato te waeine, ka taea te aukati i te pokanoa hikohiko, ā, ka tautoko i te whakaurunga muka aratau-kotahi, i te whakaurunga hononga mokowā-kore rānei, me te putanga hononga SMA, e tino āwhina ana i te whakaurunga me te whakatinanatanga. Ko te mea nui ake ko te tautoko i te whakaritenga i runga i ngā hiahia motuhake o ngā kiritaki. Hei tauira, he mea whiriwhiri te mata whakaahua-whakaahua ngongo PIN kua hangaia, e whakaatu ana i tōna taumata teitei o te ngāwari me te urutau. Ahakoa he ngoikore te mārama, ka taea tonu te whai. Mā te waeine whakaahua-whakaahua R-PR-2μm ka kitea, ka taea te ine me te whakamahi i te mārama e kore e kitea i roto i te mahi.
