Kwitekhnoloji ye-laser yanamhlanje, iimodyuli zokumpompa i-diode ziye zaba ngumthombo ofanelekileyo wempompo ye-solid-state kunye ne-fiber lasers ngenxa yokusebenza kwazo okuphezulu, ukuthembeka, kunye noyilo oludibeneyo. Nangona kunjalo, enye yezinto ezibalulekileyo ezichaphazela ukusebenza kwazo kwemveliso kunye nokuzinza kwenkqubo kukufana kokusasazwa kwenzuzo ngaphakathi kwimodyuli yempompo.
1. Yintoni iGain Distribution Uniformity?
Kwiimodyuli zokupompa i-diode, imivalo emininzi ye-laser diode ihlelwe ngokulandelelana, kwaye ukukhanya kwempompo yabo kuhanjiswe kwindawo yokuzuza (njenge-Yb-doped fiber okanye i-Nd: YAG crystal) ngokusebenzisa inkqubo ye-optical system. Ukuba ukuhanjiswa kwamandla ombane wepompo akulingani, kukhokelela kwinzuzo ye-asymmetric phakathi, okukhokelela ekubeni:
①Umgangatho we-beam othotyiweyo wemveliso ye-laser
②Ukunciphisa ukuguqulwa kwamandla okusebenza kakuhle
③Ukonyuka koxinzelelo lwe-thermal kunye nokunciphisa ixesha lokuphila kwenkqubo
④Umngcipheko ophezulu wokulimala kwamehlo ngexesha lokusebenza
Ke ngoko, ukufezekisa ukufana kwendawo ekuhanjisweni kokukhanya kwempompo yeyona njongo ibalulekileyo yobuchwephesha kuyilo lwemodyuli yempompo kunye nokuveliswa.
2. Izizathu eziqhelekileyo zokusasazwa kweNzuzo engafaniyo
①Ukwahluka kwi-Chip Emission Power
Iichips ze-laser diode ngokwendalo zibonisa ukwahluka kwamandla. Ngaphandle kokuhlelwa okufanelekileyo okanye imbuyekezo, lo mahluko unokukhokelela kuxinzelelo lwempompo olungahambelaniyo kwindawo ekujoliswe kuyo.
②Iimpazamo kwiiNkqubo zokuHlanganisa kunye nokuJolisa
Ukungalungelelani okanye iziphene kumacandelo okukhanya (umzekelo, iilensi ze-FAC/SAC, ii-microlens arrays, i-fiber couplers) zinokubangela ukuba iinxalenye ze-beam ziphambuke kwindawo ekujoliswe kuyo, ukudala iindawo ezitshisayo okanye iindawo ezifileyo.
③Iimpembelelo ze-Thermal Gradient
Iilaser zeSemiconductor zinovelwano kakhulu kubushushu. Uyilo olulambathayo lweheatsink okanye ukupholisa okungalinganiyo kunokubangela ukukhukuliseka kwamaza phakathi kweetships ezahlukeneyo, okuchaphazela ukusebenza kakuhle kokudibanisa kunye nokungaguquguquki kwemveliso.
④Uyilo lweMphumo yeFayibha enganelanga
Kwi-multi-core fiber okanye i-beam-edibanisa i-output structures, ukucwangciswa kwesiseko esingafanelekanga kunokukhokelela ekuhanjisweni kokukhanya kwempompo okungafaniyo kwindlela yokuzuza.
3. Iindlela zokuPhucula ukufumana ukuFaniswa
①Ukuhlela iChip kunye nokuTshaniswa kwamandla
Isikrini ngokuchanekileyo kunye neqela le-laser diode chips zokuqinisekisa amandla aphumayo angaguqukiyo ngaphakathi kwimodyuli nganye, ukunciphisa ukufudumeza kwendawo kunye nokufumana iindawo ezishushu.
②Uyilo oluLungileyo lwe-Optical
Sebenzisa ii-optics ezingabonisi mfanekiso okanye iilensi ze-homogenizing (umzekelo, ii-microlens arrays) ukuphucula ukugqithelana kwe-beam kunye nokugqalisela ukuchaneka, ngaloo ndlela uthambisa iprofayile yokukhanya kwempompo.
③Ulawulo lwe-Thermal olongezelelweyo
Sebenzisa izinto eziphezulu ze-thermal conductivity (umzekelo, i-CuW, i-CVD diamond) kunye nezicwangciso ezifanayo zokulawula ubushushu ukunciphisa ukuguquguquka kwe-chip-to-chip kunye nokugcina imveliso ezinzileyo.
④Ukunyanzeliswa kokukhanya kwe-Homogenization
Dibanisa izinto zokusasaza imiqadi ecaleni kwendlela yokukhanya yempompo ukuze kuphunyezwe usasazo oluthe kratya lokukhanya ngaphakathi kwendawo yokufumana.
4. Ixabiso eliSebenzayo kwi-Real-World Application
Kwiinkqubo ze-laser eziphezulu-njengokuchaneka kwemveliso, ukutyunjwa kwelaser yasemkhosini, unyango lwezonyango, kunye nophando lwezenzululwazi-ukuzinza kunye nomgangatho we-beam ye-laser output iyona nto ibalulekileyo. Ukusasazwa kwenzuzo engaqhelekanga kuchaphazela ngokuthe ngqo ukuthembeka kwenkqubo kunye nokuchaneka, ngakumbi kwezi meko zilandelayo:
①I-laser-high-energy pulsed lasers: Inqanda ukugcwala kwendawo okanye imiphumo engabonakaliyo
②I-Fiber laser amplifiers: Icinezela ukwakhiwa kwe-ASE (iAmplified Spontaneous Emission)
③I-LIDAR kunye neenkqubo zokufumana uluhlu: Ukuphucula ukuchaneka komlinganiselo kunye nokuphindaphinda
④Iilaser zonyango: Iqinisekisa ulawulo lwamandla oluchanekileyo ngexesha lonyango
5. Isiphelo
Ukufana kokusabalalisa ukuzuza kungabi yiparameter ebonakalayo yemodyuli yempompo, kodwa kubalulekile ukunika amandla ngokuthembekileyo iinkqubo ze-laser eziphezulu. Njengoko iimfuno kumgangatho we-laser kunye nokuzinza ziqhubeka nokunyuka, abavelisi bemodyuli yempompo kufuneka baphathe“ulawulo olufanayo”njengenkqubo engundoqo-Ukukhetha rhoqo itshiphu, uyilo lolwakhiwo, kunye nezicwangciso ze-thermal ukuhambisa imithombo yelaser ethembeke ngakumbi kwaye engaguqukiyo kwizicelo ezisezantsi.
