A zamani Laser fasahar, diode famfo kayayyaki sun zama manufa famfo tushen ga m-jihar da fiber Laser saboda su high dace, AMINCI, kuma m zane. Koyaya, ɗayan mahimman abubuwan da ke shafar aikin fitar da su da kwanciyar hankali na tsarin shine daidaituwar rarraba riba a cikin tsarin famfo.
1. Menene Haɗin Rarraba Rarraba?
A cikin na'urori masu yin famfo diode, ana shirya sandunan diode laser da yawa a cikin tsararru, kuma ana isar da hasken famfo su cikin matsakaicin riba (kamar Yb-doped fiber ko Nd: YAG crystal) ta hanyar tsarin gani. Idan rarraba wutar lantarki na fitilun famfo ba daidai ba ne, yana haifar da ribar asymmetric a cikin matsakaici, yana haifar da:
①Ƙarƙashin ingancin fitilun Laser
②Rage ingantaccen canjin makamashi gabaɗaya
③Ƙara yawan damuwa na thermal da rage yawan tsarin rayuwa
④Haɗarin lalacewa mafi girma yayin aiki
Don haka, samun daidaiton sararin samaniya a cikin rarraba hasken famfo shine muhimmin maƙasudin fasaha a ƙirar ƙirar famfo da masana'anta.
2. Dalilai na gama-gari na Rarraba Rashin Ribar Uniform
①Bambance-bambance a cikin Ƙarfin fitar da Chip
Chips diode Laser a zahiri suna nuna bambancin iko. Ba tare da daidaitaccen rarrabuwa ko ramuwa ba, waɗannan bambance-bambance na iya haifar da rashin daidaituwar famfo a cikin yankin da aka yi niyya.
②Kurakurai a Tsarukan Haɗuwa da Mayar da hankali
Kuskure ko lahani a cikin kayan aikin gani (misali, ruwan tabarau na FAC/SAC, tsararrun microlens, fiber couplers) na iya haifar da sassan katako don karkata daga abin da aka yi niyya, ƙirƙirar wurare masu zafi ko matattu.
③Tasirin Gindient Thermal
Semiconductor Laser suna da matukar kula da zafin jiki. Rashin ƙirar heatsink ko rashin daidaituwa na sanyaya na iya haifar da raƙuman ruwa tsakanin kwakwalwan kwamfuta daban-daban, yana shafar ingancin haɗin gwiwa da daidaiton fitarwa.
④Rashin isassun Fiber Output Design
A Multi-core fiber ko biam-hade fitarwa Tsarin, rashin daidai core layout kuma iya haifar da maras Uniform famfo haske rarraba a cikin riba matsakaici.
3. Dabaru don Inganta Samun Uniformity
①Rarraba Chip da Daidaita Wuta
Daidai allo da guntuwar diode laser na rukuni don tabbatar da daidaiton ƙarfin fitarwa a cikin kowane nau'in, rage yawan zafi na gida da samun wurare masu zafi.
②Ingantattun Zane-zane
Yi amfani da na'urorin gani marasa hoto ko ruwan tabarau masu haɗaka (misali, microlens arrays) don haɓaka juzu'in katako da daidaita daidaito, don haka daidaita bayanin martabar hasken famfo.
③Ingantattun Gudanar da Thermal
Yi amfani da kayan haɓakar zafin jiki mai girma (misali, CuW, CVD lu'u-lu'u) da dabarun sarrafa zafin jiki iri ɗaya don rage jujjuyawar zafin guntu-zuwa guntu da kiyaye ingantaccen fitarwa.
④Haɗin Ƙarfafa Haske
Haɗa masu watsawa ko abubuwa masu siffata katako tare da hanyar hasken famfo don cimma madaidaicin rarraba haske tsakanin matsakaicin riba.
4. Ƙimar Aiki a cikin Aikace-aikacen Duniya na Gaskiya
A high-karshen Laser tsarin-kamar madaidaicin sarrafa masana'antu, ƙirar laser soja, jiyya, da binciken kimiyya-kwanciyar hankali da ingancin katako na fitarwa na laser sune mafi mahimmanci. Rarraba ribar da ba ta Uniform ba tana tasiri kai tsaye ga amincin tsarin da daidaito, musamman a cikin yanayi masu zuwa:
①Laser mai ƙarfi mai ƙarfi: Yana guje wa jikewar gida ko tasirin da ba na kan layi ba
②Fiber Laser amplifiers: Yana hana ginawar ASE (Ƙarar Ƙaƙwalwar Kwatsam)
③LIDAR da tsarin gano kewayon: Inganta daidaiton aunawa da maimaitawa
④Laser na likita: Yana tabbatar da daidaitaccen ikon sarrafa kuzari yayin jiyya
5. Kammalawa
Samun daidaiton rarraba rarraba bazai zama mafi kyawun siga na ƙirar famfo ba, amma yana da mahimmanci don dogaro da dogaro da ingantaccen tsarin Laser. Kamar yadda buƙatun ingancin Laser da kwanciyar hankali ke ci gaba da hauhawa, dole ne masu masana'anta na famfo su bi da su"kula da uniformity”a matsayin ainihin tsari-akai-akai tace guntu zaɓi, tsarin tsari, da thermal dabarun sadar da mafi m da kuma m Laser kafofin zuwa ƙasa aikace-aikace.
Kuna sha'awar yadda muke haɓaka samun daidaituwa a cikin samfuran famfo ɗin mu? Tuntube mu a yau don ƙarin koyo game da mafita da tallafin fasaha.
