Njengoba izinhlelo zokusebenza ze-laser ezinamandla aphezulu ziqhubeka nokukhula, amabha e-laser diode abe yinto ebalulekile ezindaweni ezifana nokupompa nge-laser, ukucubungula kwezimboni, imishini yezokwelapha, kanye nocwaningo lwesayensi. Ngenxa yobuningi bamandla awo obuhle kakhulu, ukusabalala kwe-modular, kanye nokusebenza kahle kwe-electro-optical okuphezulu, la madivayisi ayisisekelo sezinhlelo eziningi ze-laser zanamuhla. Kodwa phakathi kwezinkomba eziningi zokusebenza kwebha ye-laser diode, ipharamitha eyodwa ivame ukunganakwa kodwa ibaluleke kakhulu: i-angle yokuhlukana. Lesi sihloko sihlola izici, imvelaphi ebonakalayo, kanye nemiphumela ye-angle yokuhlukana kumabha e-laser diode—nokuthi ukwakheka kwe-optical kungayiphatha kanjani ngempumelelo.
1. Iyini i-Divergence Angle?
I-engeli yokuhlukana ichaza indlela umsebe we-laser osakazeka ngayo njengoba usakazeka endaweni ekhululekile. Ibonisa izinga umsebe okhula ngalo kusukela endaweni yokukhipha umoya. Kumabha e-laser diode, i-engeli yokuhlukana ibonisa ukungalingani okunamandla ngezindlela ezimbili eziyinhloko:
I-Axis Esheshayo: Iqonde ngqo ebusweni bebha. Indawo yokukhishwa komoya incane kakhulu (ngokuvamile i-1–2 µm), okuholela ema-engeli amakhulu okuhlukana, ngokuvamile i-30°–45° noma ngaphezulu.
I-Axis Ehamba Kancane: Ihambisana nobude bebha. Indawo yokukhishwa kwegesi ibanzi kakhulu (amakhulu ama-micron), okuholela kuma-engeli amancane okuhlukana, ngokuvamile azungeze u-5°–15°.
Lokhu kwehlukana okungalingani kuyinselele enkulu yokuklama yokuhlanganiswa kwesistimu okubandakanya imigoqo ye-laser diode.
2. Imvelaphi Ebonakalayo Yokwehlukana
I-engeli yokuhlukana inqunywa kakhulu yisakhiwo se-waveguide kanye nosayizi we-emission facet:
Ku-axis esheshayo, indawo yokukhishwa kwegesi incane kakhulu. Ngokusho kwenkolelo-mbono yokusabalalisa, izimbobo ezincane zibangela ukuhlukana okukhulu.
Ku-axis ehamba kancane, umsebe uyakhula ngobude bebha ku-emitters eziningi, okuholela ekhoneni elincane lokuhlukana.
Ngenxa yalokho, imigoqo ye-laser diode ngokwemvelo ibonisa ukuhlukahluka okuphezulu ku-axis esheshayo kanye nokuhlukahluka okuphansi ku-axis ehamba kancane.
3. Indlela i-Divergence Angle Ethinta Ngayo Ukwakheka Kwesistimu
① Izindleko Eziphezulu Zokubumbana Nokubumba Ama-Beam
Ngenxa yokungalingani okuphezulu kwe-raw beam, kumele kusetshenziswe i-FAC (Fast Axis Collimation) kanye ne-SAC (Slow Axis Collimation). Lokhu kwandisa ubunzima besistimu futhi kudinga ukunemba okuphezulu kokufakwa kanye nokuqina kokushisa.
② Ukusebenza Kahle Kokuxhumanisa I-Fiber Okulinganiselwe
Uma kuhlanganiswa imigoqo ye-laser ibe yimicu ye-multimode, izinhlelo ze-optical, noma amalensi e-aspheric, ukuhlukana okukhulu kwe-fast-axis kungaholela "ekuchithekeni komsebe," kunciphisa ukusebenza kahle kokuxhuma. Ukuhlukana kuwumthombo omkhulu wokulahleka kokukhanya.
③ Ikhwalithi Yomsebe Ekubekweni Kwemojuli
Kumamojula ahlanganisiwe anamabha amaningi, ukuhlukana okulawulwa kabi kungabangela ukugqagqana kwemisebe okungalingani noma ukuphambuka kwendawo ekude, okuthinta ukunemba kokugxila kanye nokusatshalaliswa kokushisa.
4. Indlela Yokulawula Nokuthuthukisa Ukwehlukana Kwama-Laser Diode Bars
Nakuba ukwehluka kuchazwa kakhulu yisakhiwo sedivayisi, amasu amaningana ezingeni lesistimu angasetshenziswa ukuze kwenziwe ngcono:
①Ukusetshenziswa kwamalensi e-FAC
Ukubeka ilensi ye-fast-axis collimation eduze kwe-emitting facet kucindezela umsebe futhi kunciphisa ukuhlukana kwe-fast axis—lokhu kubalulekile emiklamo eminingi.
②Amalensi e-SAC Okwakha Okwengeziwe
Nakuba ukuhlukana kwe-slow-axis kuncane, ukwakheka kusadingeka kuma-array noma emithonjeni yokukhanya komugqa ukuze kufezwe umphumela ofanayo.
③Ukuhlanganiswa kwe-Beam kanye ne-Optical Shape Design
Ukusebenzisa ama-micro-lens arrays, ama-cylindrical lens, noma ama-optics ahlelekile kungasiza ekwakheni imisebe eminingi ye-laser ibe umphumela okhanyayo nofanayo.
④Ukuthuthukiswa Komhlahlandlela Wamagagasi Wezinga Ledivayisi
Ukulungisa ukujiya kwezingqimba ezisebenzayo, ukwakheka kwe-waveguide, kanye nezakhiwo ze-grating kungathuthukisa kakhulu ukuhlukana kwe-fast-axis kusuka ezingeni le-chip.
5. Ukulawulwa Kokwehlukahlukana Kwezinhlelo Zokusebenza Zangempela
①Imithombo Yephampu Yelaser
Ezinhlelweni ze-laser eziqinile noma ze-fiber ezinamandla aphezulu, imigoqo ye-laser diode isebenza njengemithombo yokupompa. Ukulawula ukuhlukahluka—ikakhulukazi ku-axis esheshayo—kuthuthukisa ukusebenza kahle kokuxhumanisa kanye nokugxila kwe-beam.
②Amadivayisi Ezokwelapha
Ezinhlelweni ezifana nokwelashwa nge-laser kanye nokususwa kwezinwele, ukuphatha ukwehluka kuqinisekisa ukulethwa kwamandla okufanayo kanye nokwelashwa okuphephile nokuphumelelayo.
③Ukucubungula Izinto Zezimboni
Ekushiseni nasekusikeni nge-laser, ukuhlukahluka okulungiselelwe kunegalelo ekuqineni kwamandla aphezulu, ukugxila okungcono, kanye nokucubungula okunembe kakhudlwana nokusebenza kahle.
6. Isiphetho
I-engeli yokwehluka kwebha ye-laser diode iyindawo ebalulekile yokuguquka—kusuka ku-micro-scale chip physics kuya ezinhlelweni ze-macro-scale optical.
Isebenza njengesibonakaliso sekhwalithi ye-beam kanye nomngcele womklamo wokuhlanganiswa. Njengoba izidingo zohlelo lokusebenza kanye nobunzima besistimu kuqhubeka nokukhula, ukuqonda nokulawula ukuhlukahluka kuba yikhono eliyinhloko labakhiqizi be-laser kanye nabahlanganisi ngokufanayo—ikakhulukazi ekuthuthukeleni emandleni aphezulu, ukukhanya, kanye nokuthembeka.
