A fagen manyan na'urori masu ƙarfi, sandunan Laser sune mahimman abubuwan haɗin gwiwa. Ba wai kawai suna aiki ne a matsayin mahimman raka'a na fitarwar makamashi ba, har ma sun haɗa da daidaito da haɗin kai na injiniyan optoelectronic na zamani.-samun su da sunan barkwanci: "injin" na tsarin laser. Amma menene ainihin tsarin sandar Laser, kuma ta yaya yake isar da dubun ko ma ɗaruruwan watts na fitarwa daga ƴan milimita kaɗan cikin girman? Wannan labarin yana bincikar gine-ginen ciki da sirrin injiniya a bayan sandunan Laser.
1. Menene Laser Bar?
Bar Laser babbar na'ura ce mai fitar da wutar lantarki da ta ƙunshi kwakwalwan kwamfuta na Laser diode da yawa waɗanda aka shirya a kaikaice akan madauri ɗaya. Duk da yake ka'idar aikinta ta yi kama da na laser semiconductor guda ɗaya, ma'aunin laser yana amfani da shimfidar masarrafa masu yawa don cimma ƙarfin gani mai ƙarfi da ƙarin ƙarancin tsari.
Ana amfani da sandunan Laser ko'ina a cikin masana'antu, likitanci, kimiyya, da sassan tsaro, ko dai azaman tushen laser kai tsaye ko azaman tushen famfo don laser fiber da lasers mai ƙarfi.
2. Tsarin Tsarin Laser Bar
Tsarin ciki na mashaya laser kai tsaye yana ƙayyade aikinsa. Da farko ya ƙunshi abubuwa masu zuwa:
①Emitters Array
Sandunan Laser yawanci sun ƙunshi emitters 10 zuwa 100 (cavities laser) waɗanda aka shirya gefe da gefe. Kowane emitter kusan 50 ne-150μm fadi kuma yana aiki azaman yanki mai cin gashin kansa, yana nuna mahadar PN, rami mai resonant, da tsarin jagora don samarwa da fitar da hasken laser. Duk da yake duk masu fitar da iska suna raba ƙasa ɗaya, yawanci ana sarrafa su ta hanyar lantarki a layi daya ko ta yankuna.
②Tsarin Layer Semiconductor
A tsakiyar mashaya Laser akwai tarin yadudduka na semiconductor, gami da:
- nau'in P-nau'in da nau'in nau'in nau'in epitaxial (wanda ke samar da haɗin PN)
- Layer mai aiki (misali, tsarin rijiyar quantum), wanda ke haifar da fitar da hayaki
- Waveguide Layer, yana tabbatar da sarrafa yanayin a gefe da na tsaye
- Bragg reflectors ko HR / AR coatings, wanda inganta shugabanci fitarwa na Laser
③Substrate da Tsarin Gudanar da thermal
Ana girma masu fitar da hayaki a kan madaidaicin siminkonductor (mafi yawancin GaAs). Don ingantacciyar ɓarkewar zafi, ana siyar da sandar Laser akan manyan ɗorawa masu ƙarfi kamar jan ƙarfe, W-Cu gami, ko lu'u-lu'u CVD, kuma an haɗa su tare da magudanar zafi da tsarin sanyaya aiki.
④Tsare-tsare Tsare-tsare da Haɗin Kai
Saboda manyan kusurwoyi daban-daban na fitattun katako, sandunan Laser yawanci sanye take da tsararrun ruwan tabarau (FAC/SAC) don haɗuwa da ƙirar katako. Don wasu aikace-aikace, ƙarin na'urorin gani-kamar ruwan tabarau na cylindrical ko prisms-ana amfani da su don sarrafa bambance-bambancen filin nesa da ingancin katako.
3. Mahimman Abubuwan Tsarin Tsarin Tsarin Tasirin Ayyuka
Tsarin sandar Laser yana taka muhimmiyar rawa wajen tantance kwanciyar hankali, inganci, da rayuwar sabis. Abubuwa masu mahimmanci sun haɗa da:
①Zane-zanen Gudanar da Zazzabi
Sandunan Laser sun ƙunshi babban ƙarfin ƙarfin ƙarfi da kuma tattara zafi. Ƙananan juriya na zafi yana da mahimmanci, ana samun su ta hanyar AuSn soldering ko indium bonding, haɗe tare da sanyaya microchannel don watsar da zafi iri ɗaya.
②Beam Siffar da Daidaitawa
Masu fitar da hayaki masu yawa galibi suna fama da rashin daidaituwa da rashin daidaituwar igiyar ruwa. Madaidaicin ƙirar ruwan tabarau da daidaitawa suna da mahimmanci don haɓaka ingancin katako mai nisa.
③Sarrafa damuwa da dogaro
Rashin daidaituwar kayan abu a cikin ma'aunin haɓakar zafin jiki na iya haifar da warping ko microcracks. Dole ne a tsara marufi don rarraba damuwa na inji daidai gwargwado da kuma tsayayya da hawan keke ba tare da lalacewa ba.
4. Abubuwan da ke gaba a cikin Laser Bar Design
Yayin da buƙatun ƙarfin ƙarfi, ƙarami, da mafi girman dogaro ke haɓaka, sifofin mashaya laser suna ci gaba da haɓakawa. Mahimman hanyoyin ci gaba sun haɗa da:
①Fadada Wavelength: Fadada zuwa 1.5μm da kuma tsakiyar infrared makada
②Miniaturization: Ba da damar amfani a cikin ƙananan na'urori da haɗin kai sosai
③Packaging Smart: Haɗa na'urori masu auna zafin jiki da tsarin amsa matsayi
④Maɗaukakin Maɗaukakin Maɗaukaki: Tsarukan da aka jera don cimma nasarar matakin-kilowatt a cikin ƙaramin sawun ƙafa
5. Kammalawa
Kamar yadda"zuciya”na babban iko Laser tsarin, da tsarin zane na Laser sanduna kai tsaye tasiri na gani, lantarki, da thermal yi na gaba ɗaya tsarin. Haɗa da yawa na emitters cikin tsari mai faɗi kawai millimeters ba kawai yana nuna kayan haɓakawa da fasahohin ƙirƙira ba, har ma yana wakiltar babban matakin haɗin gwiwa a yau.'s masana'antar photonics.
Neman gaba, yayin da buƙatun ingantaccen, amintattun hanyoyin laser na ci gaba da haɓaka, sabbin abubuwa a cikin tsarin mashaya Laser za su kasance babban direba don haɓaka masana'antar Laser zuwa sabon tsayi.
Idan ka'sake neman goyan bayan ƙwararru a cikin marufi na mashaya Laser, sarrafa zafi, ko zaɓin samfur, jin daɗin tuntuɓar mu. Mu'zo nan don samar da ingantattun mafita don dacewa da takamaiman bukatun aikace-aikacenku.
