Kamar yadda babban iko Laser aikace-aikace ci gaba da fadada, Laser diode sanduna sun zama makawa a yankunan kamar Laser famfo, masana'antu sarrafa, likita kayan aiki, da kuma kimiyya bincike. Tare da mafi kyawun ƙarfin ƙarfin su, daidaitawa na yau da kullun, da ingantaccen ƙarfin lantarki, waɗannan na'urori sune tushen yawancin tsarin laser na zamani. Amma duk da haka a cikin yawancin alamun wasan kwaikwayo na mashaya diode na Laser, sau da yawa ana yin watsi da siga ɗaya amma yana da mahimmanci: kusurwar banbanta. Wannan labarin yana bincika halaye, asalin zahiri, da abubuwan da ke tattare da kusurwar banbance-banbance a cikin sandunan diode laser-da kuma yadda ƙirar gani za ta iya sarrafa ta yadda ya kamata.
1. Menene Matsalolin Banbanci?
Matsakaicin bambance-bambance yana kwatanta yadda katakon Laser ke yaduwa yayin da yake yaduwa a cikin sarari kyauta. Yana nuna girman girman katakon da ke fadadawa daga fuskar fitar da iska. A cikin sandunan diode na Laser, kusurwar bambance-bambancen yana nuna ƙaƙƙarfan asymmetry a cikin manyan kwatance guda biyu:
Fast Axis: daidai gwargwado zuwa saman mashaya. Yankin da ake fitarwa yana da kunkuntar (yawanci 1-2 µm), yana haifar da manyan kusurwoyi daban-daban, yawanci 30°-45° ko fiye.
Slow Axis: Daidai da tsayin sandar. Yankin fitar da hayaki ya fi fadi (daruruwan microns), yana haifar da ƙananan kusurwoyi daban-daban, yawanci kusan 5°-15°.
Wannan bambance-bambancen asymmetric babban ƙalubalen ƙira ne don haɗa tsarin da ya ƙunshi sandunan diode laser.
2. Asalin Jiki na rarrabuwa
An ƙaddara kusurwar banbance-banbance da farko ta hanyar tsarin waveguide da girman fuska mai fitar:
A cikin axis mai sauri, wurin fitar da iska yana da ƙanƙanta. Bisa ga ka'idar diffraction, ƙananan buɗe ido suna haifar da bambance-bambance mafi girma.
A cikin jinkirin axis, katako yana faɗaɗa tare da tsayin sandar a kan masu fitar da yawa, yana haifar da ƙaramin kusurwar bambance-bambance.
Sakamakon haka, sandunan diode na Laser a zahiri suna nuna babban bambance-bambance a cikin axis mai sauri da ƙarancin rarrabuwa a cikin jinkirin axis.
3. Yadda Divergence Angle Yana Shafar Tsarin Tsarin
① Babban Kuɗin Haɗawa da Ƙaƙwalwar Ƙarfafawa
Saboda girman asymmetry na ɗanyen katako, FAC (Fast Axis Collimation) da SAC (Slow Axis Collimation) dole ne a yi amfani da na'urorin gani. Wannan yana ƙara rikitar tsarin kuma yana buƙatar ingantaccen shigarwa da kwanciyar hankali na zafi.
② Ƙarfafa Haɗin Fiber Mai iyaka
Lokacin haɗa sandunan Laser zuwa filayen multimode, tsarin gani, ko ruwan tabarau na aspheric, babban bambance-bambancen axis na iya haifar da katako “cirewa,” rage haɓakar haɗin gwiwa. Bambance-bambance shine babban tushen asarar gani.
③ Ingancin Haske a cikin Module Stacking
A cikin ma'auni masu tarin yawa, bambance-bambancen da ba a sarrafa su ba zai iya haifar da jujjuyawar katako mara daidaituwa ko murdiya mai nisa, yana shafar daidaitaccen mai da hankali da rarraba zafi.
4. Yadda ake Sarrafa da Inganta bambance-bambance a Bars Diode Laser
Kodayake tsarin na'ura ya fi bayyana bambance-bambance, ana iya amfani da dabarun matakin-tsari da yawa don ingantawa:
①Amfani da ruwan tabarau na FAC
Ajiye ruwan tabarau na haɗuwa da sauri-axis kusa da fuskar da ke fitarwa yana danne katako kuma yana rage rarrabuwa a cikin axis mai sauri-wannan yana da mahimmanci a yawancin ƙira.
②Lens na SAC don ƙarin Siffar
Ko da yake jinkirin-axis bambance-bambancen ya fi ƙanƙanta, ana buƙatar yin siffa a cikin tsararraki ko hanyoyin hasken layi don cimma fitowar iri ɗaya.
③Haɗuwa da Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwararren Ƙwaƙwalwa
Yin amfani da tsararrun ruwan tabarau, ruwan tabarau na cylindrical, ko tsarin gani na gani na iya taimakawa wajen tsara katakon Laser da yawa zuwa haske mai haske, fitarwa iri ɗaya.
④Inganta Matsayin Na'ura Waveguide
Daidaita kaurin Layer mai aiki, ƙirar waveguide, da tsarin grating na iya ƙara daidaita bambance-bambancen axis mai sauri daga matakin guntu.
5. Gudanar da Bambance-bambance a cikin Aikace-aikacen Duniya na Gaskiya
①Laser Pump Sources
A high-ikon m-jihar ko fiber Laser tsarin, Laser diode sanduna zama famfo kafofin. Sarrafa rarrabuwar kawuna-musamman a cikin axis mai sauri-yana haɓaka haɓakar haɗin gwiwa da mai da hankali kan katako.
②Na'urorin likitanci
Don tsarin kamar maganin laser da cire gashi, sarrafa rarrabuwar kawuna yana tabbatar da isar da makamashi iri ɗaya da aminci, ingantaccen magani.
③Sarrafa Kayan Masana'antu
A Laser waldi da yankan, gyara rarrabẽwa na taimaka wa mafi girma iko yawa, mafi mayar da hankali, kuma mafi daidai, m aiki.
6. Kammalawa
Madaidaicin kusurwar sandar diode na Laser shine mahimmin wurin miƙa mulki-daga ƙananan sikelin guntu kimiyyar lissafi zuwa tsarin gani na ma'auni.
Yana aiki azaman duka alamar ingancin katako da iyakar ƙira don haɗawa. Kamar yadda buƙatun aikace-aikacen da sarkar tsarin ke ci gaba da haɓakawa, fahimta da sarrafa rarrabuwar kawuna ya zama babban cancanta ga masana'antun Laser da masu haɗawa iri ɗaya-musamman don haɓaka zuwa mafi girma ƙarfi, haske, da aminci.
