Kubuchwepheshe besimanje be-laser, amamojula okumpompa ama-diode abe umthombo wephampu ofanele wama-solid-state kanye nama-laser fiber ngenxa yokusebenza kahle kwawo okuphezulu, ukwethembeka, kanye nomklamo ohlangene. Kodwa-ke, enye yezinto ezibalulekile ezithinta ukusebenza kwabo kokuphumayo nokuzinza kwesistimu ukufana kokusatshalaliswa kwenzuzo ngaphakathi kwemoduli yepompo.
1. Iyini i-Gain Distribution Uniformity?
Kumamojula wokupompa ama-diode, amabha amaningi e-laser diode ahlelwa ngohlelo, futhi ukukhanya kwawo kwepompo kulethwa endaweni yokuthola (njenge-Yb-doped fiber noma i-Nd:YAG crystal) ngesistimu yokubona. Uma ukusatshalaliswa kwamandla kwesibani sephampu kungalingani, kuholela enzuzweni ye-asymmetric phakathi nendawo, okuholela ku:
①Ikhwalithi ye-beam eyehlisiwe yokuphuma kwe-laser
②Kwehliswe ukusebenza kahle kokuguqulwa kwamandla sekukonke
③Ukwenyuka kwengcindezi yokushisa kanye nokunciphisa impilo yesistimu
④Ingozi ephezulu yokulimala kwe-optical ngesikhathi sokusebenza
Ngakho-ke, ukuzuza ukufana kwendawo ekusabalaliseni ukukhanya kwephampu kuyinjongo yezobuchwepheshe ebalulekile ekwakhiweni kwemojula yephampu nokukhiqiza.
2. Izimbangela Ezijwayelekile Zokusabalalisa Okungafani Okufanayo
①Ukwehluka Kwamandla Okukhishwa Kwe-Chip
Ama-chips e-laser diode akhombisa ukwehluka kwamandla. Ngaphandle kokuhlunga okufanele noma isinxephezelo, lo mehluko ungaholela ekushubeni kwephampu okungahambisani kuyo yonke indawo okuhlosiwe.
②Amaphutha Ezinhlelweni Zokuhlanganisa Nezokugxila
Ukungaqondani kahle noma amaphutha ezingxenyeni ezibonakalayo (isb., amalensi e-FAC/SAC, ama-microlens array, ama-fiber couplers) angabangela izingxenye ze-beam ukuthi ziphambuke kulokho okuhlosiwe, kudaleke izindawo ezishisayo noma izindawo ezifile.
③I-Thermal Gradient Effects
Ama-laser we-semiconductor azwela kakhulu izinga lokushisa. Idizayini ye-heatsink engalungile noma ukupholisa okungalingani kungabangela ukukhukhuleka kwe-wavelength phakathi kwama-chips ahlukene, kuthinte ukusebenza kahle kokuhlanganisa kanye nokuvumelana kokuphumayo.
④I-Fiber Output Design enganele
Ku-multi-core fiber noma izakhiwo ezihlanganisa i-beam, ukwakheka okuyinhloko okungalungile kungase futhi kubangele ukusabalaliswa kokukhanya kwephampu okungajwayelekile endaweni yokuzuza.
3. Amasu Okuthuthukisa Ukuzuza Ukufana
①Ukuhlunga kwe-Chip kanye Nokumatanisa Amandla
Khipha ngokuqondile kanye nama-chips e-laser diode yeqembu ukuze uqinisekise amandla okukhiphayo angaguquki ngaphakathi kwemojuli ngayinye, unciphise ukushisisa okwedlulele kwendawo futhi uthole izindawo ezishisayo.
②Idizayini Ye-Optical Elungiselelwe
Sebenzisa ama-optics angabonisi isithombe noma amalensi e-homogenizing (isb., ama-microlens array) ukuze uthuthukise ukugqagqana kwe-beam kanye nokunemba kokugxila, ngaleyo ndlela wenze isicaba sephrofayela yokukhanya kwephampu.
③Ukuphatha Okushisayo Okuthuthukisiwe
Sebenzisa izinto eziphezulu ze-thermal conductivity (isb, i-CuW, idayimane le-CVD) kanye namasu afanayo okulawula izinga lokushisa ukuze unciphise ukuguquguquka kwezinga lokushisa kwe-chip-to-chip nokugcina okukhiphayo okuzinzile.
④I-Light Intensity Homogenization
Hlanganisa ama-diffuser noma ama-elementi abumba i-beam eduze kwendlela yokukhanya yepompo ukuze uzuze ukusatshalaliswa kokukhanya kwendawo ngaphakathi kwendawo yokuthola.
4. Inani Elisebenzayo Kuzicelo Zomhlaba Wangempela
Ezinhlelweni ze-laser eziphezulu-njengokunemba kokucubungula kwemboni, ukuqokwa kwelaser yezempi, ukwelashwa, kanye nocwaningo lwesayensi-ukuzinza kanye nekhwalithi ye-beam yokuphuma kwe-laser kubaluleke kakhulu. Ukusatshalaliswa kwenzuzo okungeyona into efanayo kuthinta ngokuqondile ukwethembeka nokunemba kwesistimu, ikakhulukazi kulezi zimo ezilandelayo:
①Ama-laser anamandla aphezulu: Agwema ukugcwala kwendawo noma imiphumela engaqondile
②I-Fiber laser amplifiers: Icindezela i-ASE (Amplified Spontaneous Emission) ukwakha
③I-LIDAR nezinhlelo zokuthola ububanzi: Ithuthukisa ukunemba kokulinganisa nokuphindaphinda
④Amalaser ezokwelapha: Iqinisekisa ukulawulwa kwamandla okunembile ngesikhathi sokwelashwa
5. Isiphetho
Ukufana kokusabalalisa kwenzuzo kungase kungabi ipharamitha ebonakala kakhulu yemojula yephampu, kodwa kubalulekile ukuze kunikwe amandla ngokuthembekile amasistimu e-laser asebenza kahle kakhulu. Njengoba izimfuno zekhwalithi ye-laser nokuzinza ziqhubeka nokukhuphuka, abakhiqizi bemojula yepompo kufanele baphathe“ukulawula ukufana”njengenqubo ewumgogodla-Ukucwenga njalo ukukhetha kwe-chip, ukwakheka kwesakhiwo, namasu okushisa okuletha imithombo ye-laser enokwethenjelwa futhi engaguquguquki ezinhlelweni zokusebenza ezansi nomfula.
Unentshisekelo yokuthi sithuthukisa kanjani ukuzuza okufanayo kumamojula wethu wepompo? Xhumana nathi namuhla ukuze ufunde kabanzi mayelana nezixazululo zethu nokusekelwa kobuchwepheshe.
