Njengoko izicelo ze-laser ezinamandla aphezulu ziqhubeka zisanda, imivalo ye-laser diode ibaluleke kakhulu kwimimandla efana nokumpompa ngelaser, ukusetyenzwa kwemizi-mveliso, izixhobo zonyango, kunye nophando lwezenzululwazi. Ngoxinaniso lwamandla lwazo olugqwesileyo, ukukala kwemodyuli, kunye nempumelelo ephezulu ye-electro-optical, ezi zixhobo zingundoqo weenkqubo ezininzi zelaser zanamhlanje. Ukanti phakathi kwezalathisi ezininzi zokusebenza ze-laser diode bar, iparameter enye ihlala ingahoywa kodwa ibaluleke kakhulu: i-divergence angle. Eli nqaku liphonononga iimpawu, imvelaphi yomzimba, kunye neempembelelo ze-angle yokuhlukana kwii-laser diode bar-kunye nendlela uyilo lwe-optical olunokuyilawula ngayo ngokufanelekileyo.
1. Yintoni i-engile yokuhlukana?
I-angle yokuhlukana ichaza indlela i-laser beam esasazeka ngayo njengoko isasazeka kwindawo ekhululekile. Ibonisa indlela umqadi owanda ngayo ukusuka kwindawo yokukhupha. Kwimivalo ye-laser diode, i-angle yokuhlukana ibonisa i-asymmetry eyomeleleyo kwiindlela ezimbini eziphambili:
I-Axis ekhawulezayo: I-Perpendicular kumphezulu webar. Ummandla okhutshwayo umxinwa kakhulu (ngokuqhelekileyo yi-1–2 µm), ekhokelela kwii-engile zokwahlukana okukhulu, rhoqo ngama-30°–45° okanye ngaphezulu.
I-Slow Axis: Ingqamene nobude bebha. Ummandla okhutshwayo ubanzi kakhulu (amakhulu ee-microns), okukhokelela kwii-engile zokwahlukana ezincinci, ngokuqhelekileyo malunga ne-5 ° -15 °.
Oku kuhlukana kwe-asymmetric ngumngeni omkhulu woyilo lokudityaniswa kwenkqubo ebandakanya imivalo ye-laser diode.
2. Imvelaphi yePhysical Divergence
I-angle yokuhlukana imiselwa ikakhulu sisakhiwo se-waveguide kunye nobukhulu becala lokukhupha:
Kwi-axis ekhawulezayo, indawo yokukhupha incinci kakhulu. Ngokwethiyori ye-diffraction, imingxuma emincinci ikhokelela kwiyantlukwano enkulu.
Kwi-axis ecothayo, umqadi uyanda ngobude bebha kwi-emitter ezininzi, okukhokelela kwi-angle encinci yokwahlukana.
Ngenxa yoko, imivalo ye-laser diode ngokwendalo ibonisa iyantlukwano ephezulu kwi-axis ekhawulezayo kunye nokwahlukana okuphantsi kwi-axis ecothayo.
3. Indlela iDivergence Angle ichaphazela ngayo uYilo lweNkqubo
① Iindleko eziPhakamileyo zokuDibanisa kunye nokuBunjwa kweBeam
Ngenxa ye-asymmetry ephezulu ye-beam eluhlaza, i-FAC (i-Fast Axis Collimation) kunye ne-SAC (i-Slow Axis Collimation) kufuneka isetyenziswe. Oku kwandisa ubunzima benkqubo kwaye kufuna ukuchaneka okuphezulu kofakelo kunye nokuzinza kwe-thermal.
② IFayibha eDityanisiweyo eNcinciweyo ngokuFanelekileyo
Xa udibanisa imivalo yelaser kwiintsinga zemultimode, iinkqubo zamehlo, okanye iilensi ze-aspheric, umahluko omkhulu okhawulezayo we-axis unokukhokelela kwi-beam "spillover," ukunciphisa ukusebenza kakuhle kokudibanisa. Ukwahlukana ngumthombo omkhulu welahleko yamehlo.
③ Umgangatho weBeam kwiModyuli yokuFakwa
Kwiimodyuli ezifakwe kwii-bar ezininzi, ukuhlukana okungalawulwa kakuhle kunokubangela ukugqithwa kwe-beam engalinganiyo okanye ukuphazamiseka kwendawo ekude, echaphazela ukuchaneka kokuchaneka kunye nokusabalalisa kwe-thermal.
4. Indlela yokulawula kunye nokuphucula iDivergence kwiiBar zeDiode zeLaser
Nangona iyantlukwano ichazwa kakhulu sisimo sesixhobo, iindlela ezininzi zenqanaba lenkqubo zinokusetyenziselwa ukufaneleka:
①Ukusetyenziswa kweeLensi zeFAC
Ukubeka i-lens ekhawulezayo yokudibanisa i-lens kufuphi ne-facet ekhuphayo ixinzelela umqadi kwaye inciphisa ukuhlukana kwi-axis ekhawulezayo-oku kubalulekile kuninzi loyilo.
②IiLensi ze-SAC zokuMila okoNgezelelweyo
Nangona iyantlukwano ecothayo ye-axis incinci, ukubunjwa kusafuneka kuluhlu okanye imithombo yokukhanya komgca ukufikelela kwimveliso efanayo.
③Ukudityaniswa kweBeam kunye noYilo lwe-Optical Shaping
Ukusebenzisa i-micro-lens arrays, iilensi ze-cylindrical, okanye i-optics eyakhiweyo inokunceda ukubumba imiqadi ye-laser emininzi ibe ngukukhanya okuphezulu, ukukhutshwa okufanayo.
④Isixhobo-Inqanaba leWaveguide Optionation
Ukulungelelanisa ubungqingqwa bomaleko osebenzayo, uyilo lwe-waveguide, kunye nezakhiwo zegrayiti zinokucokisa ngakumbi umahluko okhawulezayo we-axis ukusuka kwinqanaba le-chip.
5. Ukulawulwa kweDivergence kwi-Real-World Application
①Imithombo yeMpompo yeLaser
Kwiinkqubo eziphezulu zamandla aqinileyo okanye i-fiber laser, imivalo ye-laser diode isebenza njengemithombo yempompo. Ukulawula ukuhlukana-ngokukodwa kwi-axis ekhawulezayo-kuphucula ukudibanisa ukusebenza kakuhle kunye nokugxilwa kwe-beam.
②Izixhobo zonyango
Kwiinkqubo ezifana nonyango lwelaser kunye nokususwa kweenwele, ukulawula ukwahluka kuqinisekisa ukuhanjiswa kwamandla afanayo kunye nokhuseleko, unyango olusebenzayo ngakumbi.
③Ukwenziwa kweMathiriyeli yeShishini
Kwi-laser welding kunye nokusika, ukwahluka okuphuculweyo kunegalelo ekuxinaniseni kwamandla aphezulu, kugxilwe ngcono, kunye nokuchaneka ngakumbi, ukusebenza ngokufanelekileyo.
6. Isiphelo
I-angle ye-divergence ye-laser diode bar yindawo ebalulekileyo yokutshintsha-ukusuka kwi-micro-scale chip physics ukuya kwii-macro-scale optical systems.
Isebenza njengesalathisi somgangatho we-beam kunye nomda woyilo wokudibanisa. Njengoko iimfuno zesicelo kunye nobunzima benkqubo buqhubeka bukhula, ukuqonda kunye nokulawula ukuhlukana kuba yinto ephambili yobuchule kubenzi be-laser kunye nabahlanganisi ngokufanayo-ingakumbi ukuqhubela phambili kumandla aphezulu, ukukhanya, kunye nokuthembeka.
