Juyawar gargajiyaMai daidaita LiNbO3
Kwanan nan, wata ƙungiyar bincike a China ta buga takardar mallakar fasaha ta ƙirƙirar fasahar kulle mitar laser ta amfani da na'urar sarrafa LiNbO3. Babban tsarin haƙƙin mallakar fasaha shine sabon tsarin kulle mitar laser PDH (Pound Driver Hall) wanda ke juya hanyoyin gargajiya.
1. Wuraren da fasahar gargajiya ke fama da su:
Tsarin kulle mitar PDH na gargajiya galibi ana amfani da lithium niobate (LiNbO3)na'urar sarrafa na'urar lantarki (electro-optical modulator)don samar da madaurin gefen gani da ake buƙata. Wannan hanyar tana da manyan matsaloli guda uku: tsada mai yawa da tsari mai rikitarwa (yana buƙatar da'irori masu rikitarwa na direbobin RF), jin daɗin muhalli (canje-canjen zafin jiki da damuwa na iya haifar da aiki mara ƙarfi cikin sauƙi), da tasirin daidaita girman da ya rage (RAM), wanda zai iya haifar da karkatar da siginar kullewa kuma yana da tasiri sosai ga kwanciyar hankali na tsarin na dogon lokaci.
2. Sabbin hanyoyin magance matsaloli:
Ƙungiyoyin bincike na ƙasar Sin sun yi watsi da na'urar lantarki ta gargajiya gaba ɗaya. Babban ƙirƙira ya ta'allaka ne a cikin haɗin gwiwar ƙira na "mai ƙara haske na semiconductor (SOA amplifier) tare da mai canza mitar acousto-optic dual channel (AOM modulator)". Ka'idar ta musamman ita ce: bayan raba hasken laser iri, biyuMai daidaita AOMAna amfani da su don daidaitaccen canjin mita, sannan a saka waɗannan hasken guda biyu a cikin amplifier SOA a cikin yanayin jikewa mai yawa. Yana samar da siginar gefe da yawa da ake buƙata don kulle mitar PDH ta hanyar amfani da tasirin da ba na layi ba kamar haɗawar raƙuman ruwa huɗu (FWM) a cikinAmplifier SOA.
3. Fa'idodin aiki da suka zo ta hanyar:
Kwanciyar hankali: Na'urorin SOA (kamar marufin malam buɗe ido) an haɗa su da tsarin sarrafa zafin jiki kuma ba sa damuwa da matsalolin muhalli, suna kawar da tasirin RAM daga tsarin jiki da kuma cimma matsaya mai matuƙar daidaito na dogon lokaci (mafi kyau fiye da 5 × 10¹¹¹/rana).
Babban rabon sigina zuwa hayaniya: Ta hanyar sarrafa canjin mita na mai daidaita AOM guda biyu kai tsaye, yana yiwuwa a cimma daidaito daidai tsakanin mitar gefen da kewayon spectral kyauta (FSR) na ramin tunani, ta haka yana inganta rabon sigina zuwa hayaniyar siginar kuskure sosai.
Rage farashi da rage farashi: Amplifier na SOA yana kawar da masu amfani da wutar lantarki masu tsada da kuma da'irori masu rikitarwa, wanda ke buƙatar sauƙin tuƙi na wutar lantarki kawai. Wannan yana sa tsarin ya fi ƙanƙanta kuma ya fi araha, wanda hakan ke taimakawa wajen cimma ƙarancin kayan aiki da kuma amfaninsu.
4. Abubuwan da ake buƙata na aikace-aikace da kuma buƙatar kasuwa:
Wannan fasaha ta dace daidai da buƙatar manyan hanyoyin laser masu ƙarfi a cikin haɓaka fasahar quantum, kuma tana da fa'idodi masu yawa na amfani, gami da:
Agogon haske da aka ɗora a sarari da abin hawa (dole ne ya yi tsayayya da girgiza mai tsanani).
Na'urar auna nauyi ta Quantum da kuma na'urar auna zafin atom (wanda ake amfani da shi don binciken ƙasa da kuma kewayawa a ƙarƙashin ruwa).
Na'urar hangen nesa ta fiber optic da LiDAR.
A kasuwar da ake ciki a yanzu, musamman a fannin binciken kimiyya, masana'antar soja, da kuma harkokin sararin samaniya na kasuwanci, akwai karuwar bukatar na'urorin laser masu dorewa, masu rahusa, da kuma masu dorewa daga kamfanoni. Wannan fasahar mallakar fasaha ta kama wannan yanayin kasuwa daidai.
