Kubuchwepheshe be-laser besimanje, amamojula okupompa ama-diode abe ngumthombo ofanele wephampu yama-laser aqinile kanye ne-fiber ngenxa yokusebenza kwawo kahle, ukuthembeka, kanye nomklamo ohlangene. Kodwa-ke, esinye sezici ezibalulekile ezithinta ukusebenza kwawo kokukhipha kanye nokuqina kohlelo ukufana kokusatshalaliswa kwenzuzo ngaphakathi kwemojula yephampu.
1. Kuyini i-Gain Distribution Uniformity?
Kumamojula okupompa ama-diode, imigoqo eminingi ye-laser diode ihlelwe ngendlela efanayo, futhi ukukhanya kwayo kwephampu kulethwa endaweni yokuzuza (njenge-fiber efakwe i-Yb noma i-Nd:YAG crystal) ngohlelo lwe-optical. Uma ukusatshalaliswa kwamandla kokukhanya kwephampu kungalingani, kuholela ekuzuzeni okungalingani endaweni yokuzuza, okuholela ku:
①Ikhwalithi yokukhanya kwe-laser ewohlokile
②Ukunciphisa ukusebenza kahle kokuguqulwa kwamandla
③Ukucindezeleka okwandayo kokushisa kanye nokuphila kwesikhathi esinciphile kwesistimu
④Ingozi ephezulu yokulimala kwamehlo ngesikhathi sokusebenza
Ngakho-ke, ukufeza ukufana kwendawo ekusabalalisweni kokukhanya kwephampu kuyinjongo ebalulekile yobuchwepheshe ekwakhiweni nasekukhiqizweni kwemojula yephampu.
2. Izimbangela Ezivamile Zokusatshalaliswa Kwenzuzo Engalingani
①Izinguquko ku-Chip Emission Power
Ama-chip e-laser diode abonisa ukushintshashintsha kwamandla ngokwemvelo. Ngaphandle kokuhlunga noma ukunxephezela okufanele, lokhu kungafani kungaholela ekuqineni kwephampu okungalingani kuyo yonke indawo eqondiwe.
②Amaphutha Ezinhlelweni Zokuhlanganisa Nokugxila
Ukungalungi kahle noma amaphutha ezingxenyeni ze-optical (isb., amalensi e-FAC/SAC, ama-microlens arrays, ama-fiber couplers) kungabangela ukuthi izingxenye zomsebe ziphambuke kulokho okuhlosiwe, okudala izindawo ezishisayo noma izindawo ezifile.
③Imiphumela ye-Thermal Gradient
Ama-laser e-semiconductor azwela kakhulu ekushiseni. Ukwakheka kwe-heatsink okungekuhle noma ukupholisa okungalingani kungabangela ukukhukhuleka kwe-wavelength phakathi kwama-chip ahlukene, okuthinta ukusebenza kahle kokuxhumanisa kanye nokungaguquguquki kokukhipha.
④Umklamo Wokukhipha I-Fiber Onganele
Ezindaweni zokukhipha i-fiber enezinsika eziningi noma ezihlanganisa imisebe, ukwakheka okungalungile kwensika kungabangela nokusatshalaliswa kokukhanya kwephampu okungafani endaweni yokuzuza.
3. Amasu Okuthuthukisa Ukuzuza Ukufana
①Ukuhlunga Ama-Chip Nokufaniswa Kwamandla
Hlola ngokunembile futhi uqoqe ama-chip e-laser diode ukuqinisekisa amandla okukhipha ahambisanayo ngaphakathi kwemojuli ngayinye, unciphise ukushisa okwedlulele kwendawo futhi uthole izindawo ezishisayo.
②Umklamo Obonakalayo Olungiselelwe
Sebenzisa ama-optics angewona ama-imaging noma amalensi e-homogenizing (isb., ama-microlens arrays) ukuze uthuthukise ukugqagqana kwemisebe kanye nokunemba kokugxila, ngaleyo ndlela wehlise iphrofayili yokukhanya kwephampu.
③Ukuphathwa Okuthuthukisiwe Kokushisa
Sebenzisa izinto zokushisa eziphezulu (isb., i-CuW, i-CVD diamond) kanye namasu okulawula izinga lokushisa afanayo ukuze unciphise ukushintshashintsha kwezinga lokushisa kusuka ku-chip kuya ku-chip futhi ugcine umkhiqizo ozinzile.
④Ukuhlanganiswa Kokukhanya Okunamandla
Faka ama-diffuser noma izinto ezibumba imisebe endleleni yokukhanya kwephampu ukuze ufinyelele ukusatshalaliswa kokukhanya okulinganayo ngaphakathi kwendawo yokuzuza.
4. Ukubaluleka Okusebenzayo Ezicelweni Zomhlaba Wangempela
Ezinhlelweni ze-laser ezisezingeni eliphezulu—njengokucubungula kwezimboni ngokunemba, ukuqokwa kwe-laser yezempi, ukwelashwa kwezokwelapha, kanye nocwaningo lwesayensi—ukuzinza kanye nekhwalithi yokukhanya kokukhishwa kwe-laser kubaluleke kakhulu. Ukusatshalaliswa kokuzuza okungalingani kuthinta ngqo ukuthembeka nokunemba kohlelo, ikakhulukazi ezimweni ezilandelayo:
①Ama-laser anamandla aphezulu okushaya umoya: Agwema ukugcwala kwendawo noma imiphumela engeyona eye-linear
②Ama-amplifiers e-laser yefayibha: Acindezela ukwakheka kwe-ASE (Amplified Spontaneous Emission)
③Izinhlelo ze-LIDAR kanye nokuthola ububanzi: Zithuthukisa ukunemba kokulinganisa kanye nokuphindeka
④Ama-laser ezokwelapha: Iqinisekisa ukulawulwa kwamandla okunembile ngesikhathi sokwelashwa
5. Isiphetho
Ukufana kokusabalalisa kwenzuzo kungase kungabi yipharamitha ebonakala kakhulu yemojuli yepompo, kodwa kubalulekile ekunikezeni amandla ngokuthembekile izinhlelo ze-laser ezisebenza kahle kakhulu. Njengoba izidingo zekhwalithi ye-laser kanye nokuqina ziqhubeka nokukhula, abakhiqizi bemojuli yepompo kumele baphathe"ukulawula ukufana"njengenqubo eyinhloko—ukucwenga njalo ukukhethwa kwama-chip, ukwakheka kwesakhiwo, kanye namasu okushisa ukuze kuhlinzekwe imithombo ye-laser ethembekile futhi ehambisanayo ezinhlelweni zokusebenza ezingezansi.
Unesifiso sokwazi ukuthi sithuthukisa kanjani ukufana kwe-gain kumamojula ethu epompo? Xhumana nathi namuhla ukuze ufunde kabanzi ngezixazululo zethu kanye nokusekelwa kobuchwepheshe.
