Njengoko usetyenziso lwe-laser enamandla aphezulu luqhubeka nokukhula, ii-laser diode bars ziye zaba yinto ebalulekileyo kwiindawo ezifana nokupompa nge-laser, ukucubungula imboni, izixhobo zonyango, kunye nophando lwesayensi. Ngenxa yobuninzi bazo bamandla, ukulinganiswa kwemodyuli, kunye nokusebenza kakuhle kwe-electro-optical, ezi zixhobo ziphambili kwiinkqubo ezininzi ze-laser zanamhlanje. Kodwa phakathi kwezalathisi ezininzi zokusebenza kwe-laser diode bar, ipharamitha enye idla ngokunganakwa kodwa ibaluleke kakhulu: i-divergence angle. Eli nqaku liphonononga iimpawu, imvelaphi yomzimba, kunye neziphumo ze-divergence angle kwii-laser diode bars—kunye nendlela uyilo lwe-optical olunokuyilawula ngayo ngempumelelo.
1. Yintoni i-Divergence Angle?
I-engile ye-divergence ichaza indlela umqadi we-laser osasazeka ngayo njengoko usasazeka kwindawo ekhululekileyo. Ibonisa ubungakanani bomqadi okhula ngayo ukusuka kwi-emission facet. Kwii-laser diode bars, i-engile ye-divergence ibonisa i-asymmetry enamandla kwiindlela ezimbini eziphambili:
I-Axis ekhawulezayo: Ithe nkqo kumphezulu webha. Ummandla wokukhupha umbane mxinwa kakhulu (ngesiqhelo yi-1–2 µm), nto leyo ekhokelela kwii-engile ezinkulu zokwahlukana, ezidla ngokuba yi-30°–45° nangaphezulu.
I-Axis ecothayo: Ihambelana nobude bebha. Ummandla wokukhupha umbane ubanzi kakhulu (amakhulu ee-microns), nto leyo ebangela ii-engile ezincinci zokwahlukana, ngokuqhelekileyo malunga ne-5°–15°.
Oku kwahluka okungalinganiyo ngumceli mngeni omkhulu woyilo lokudibanisa iinkqubo ezibandakanya iibha ze-laser diode.
2. Imvelaphi Yokwahluka Ngokwendalo
I-engile yokwahluka imiselwa ikakhulu yisakhiwo se-waveguide kunye nobungakanani be-emission facet:
Kwi-axis ekhawulezayo, indawo yokukhupha umbane incinci kakhulu. Ngokwethiyori ye-diffraction, ii-apertures ezincinci zibangela ukwahlukana okukhulu.
Kwi-axis ecothayo, umqadi uyakhula kubude bebha kwii-emitters ezininzi, nto leyo ebangela i-engile encinci yokwahlukana.
Ngenxa yoko, iibha ze-laser diode ngokwemvelo zibonisa umahluko ophezulu kwi-axis ekhawulezayo kunye nomahluko ophantsi kwi-axis ecothayo.
3. Indlela i-Divergence Angle echaphazela ngayo uyilo lwenkqubo
① Ixabiso Eliphezulu Lokubumbana Nokubumba Imisebe
Ngenxa yokungalingani okuphezulu kwe-raw beam, kufuneka kusetyenziswe i-FAC (Fast Axis Collimation) kunye ne-SAC (Slow Axis Collimation). Oku kwandisa ubunzima benkqubo kwaye kufuna ukuchaneka okuphezulu kokufakwa kunye nozinzo lobushushu.
② Ukusebenza kakuhle kweFiber Coupling
Xa kuhlanganiswa iibha zelaser kwiifayibha ze-multimode, iinkqubo ze-optical, okanye iilensi ze-aspheric, ukuhlukana okukhulu kwe-fast-axis kunokukhokelela "ekuchithekeni komsebe," kunciphisa ukusebenza kakuhle kwe-coupling. Ukuhlukana ngumthombo omkhulu wokulahleka kwe-optical.
③ Umgangatho weBeam kwiModule Stacking
Kwiimodyuli ezifakwe kwiibha ezininzi, ukwahluka okulawulwa kakubi kunokubangela ukugqithana kwemisebe okungalinganiyo okanye ukuphazamiseka kwendawo ekude, okuchaphazela ukuchaneka kokugxila kunye nokusasazwa kobushushu.
4. Indlela yokulawula nokuphucula ukuhlukahluka kweebha zeLaser Diode
Nangona ukwahluka kuchazwa kakhulu bulwakhiwo lwesixhobo, amaqhinga amaninzi kwinqanaba lenkqubo angasetyenziselwa ukuphucula:
①Ukusetyenziswa kweeLensi zeFAC
Ukubeka ilensi ye-fast-axis collimation kufutshane ne-emitting facet kuyayicinezela i-beam kwaye kunciphisa umahluko kwi-fast axis—oku kubalulekile kwiindidi ezininzi zoyilo.
②Iilensi ze-SAC zokuBumba okongezelelweyo
Nangona umahluko we-slow-axis umncinci, ukwakheka kusafuneka kwii-arrays okanye kwimithombo yokukhanya komgca ukuze kufezekiswe imveliso efanayo.
③Ukudibanisa imiqadi kunye noyilo lokubumba okukhanya
Ukusebenzisa ii-micro-lens arrays, ii-cylindrical lens, okanye ii-structured optics kunokunceda ekwakheni imisebe emininzi ye-laser ibe yimveliso ekhanyayo nefanayo.
④Ukulungiswa kwe-Waveguide yeLevel-Level yesixhobo
Ukulungisa ubukhulu be-active layer, uyilo lwe-waveguide, kunye nezakhiwo ze-grating kunokuphucula ngakumbi umahluko we-fast-axis ukusuka kwinqanaba le-chip.
5. Ulawulo lokwahluka kwii-Applications zeHlabathi lokwenyani
①Imithombo yePump yeLaser
Kwiinkqubo ze-laser eziqinileyo okanye ezinefayibha ezinamandla aphezulu, iibha ze-laser diode zisebenza njengemithombo yepompo. Ukulawula umahluko—ingakumbi kwi-axis ekhawulezayo—kuphucula ukusebenza kakuhle kwe-coupling kunye nokugxila kwe-beam.
②Izixhobo zonyango
Kwiinkqubo ezifana nonyango lwelaser kunye nokususwa kweenwele, ukulawula umahluko kuqinisekisa ukuhanjiswa kwamandla okufanayo kunye nonyango olukhuselekileyo nolusebenzayo ngakumbi.
③Ukucubungula Izinto Zoshishino
Kwi-laser welding and cutting, umahluko owenziwe kakuhle unegalelo ekuxineni kwamandla aphezulu, ekugxileni okungcono, nasekucutshungulweni okuchanekileyo nokusebenzayo.
6. Isiphelo
I-engile yokwahluka kwe-laser diode bar yindawo ebalulekileyo yotshintsho—ukusuka kwi-micro-scale chip physics ukuya kwiinkqubo ze-macro-scale optical.
Isebenza njengesalathisi somgangatho wemitha kunye nomda woyilo lokudibanisa. Njengoko iimfuno zesicelo kunye nobunzima benkqubo ziqhubeka zikhula, ukuqonda nokulawula umahluko kuba yinxalenye ebalulekileyo yabenzi be-laser kunye nabahlanganisi ngokufanayo—ingakumbi ekuqhubekeni ukuya kumandla aphezulu, ukukhanya, kunye nokuthembeka.
