Kwitekhnoloji yelaser yanamhlanje, iimodyuli zokumpompa iidiode ziye zaba ngumthombo ofanelekileyo wepompo kwiilaser eziqinileyo kunye neefayibha ngenxa yokusebenza kwazo okuphezulu, ukuthembeka, kunye noyilo oluncinci. Nangona kunjalo, enye yezinto ezibalulekileyo ezichaphazela ukusebenza kwazo kwemveliso kunye nozinzo lwenkqubo kukufana kokusasazwa kwenzuzo kwimodyuli yepompo.
1. Yintoni iGain Distribution Uniformity?
Kwiimodyuli zokumpompa ii-diode, iibha ze-laser diode ezininzi zicwangciswe ngokwamaqela, kwaye ukukhanya kwazo kwepompo kuhanjiswa kwi-gain medium (njenge-Yb-doped fiber okanye i-Nd:YAG crystal) ngenkqubo ye-optical. Ukuba ukusasazwa kwamandla kokukhanya kwepompo akulingani, kukhokelela kwi-asymmetric gain kwi-medium, nto leyo ebangela oku kulandelayo:
①Umgangatho womqadi ophantsi wemveliso yelaser
②Ukunciphisa ukusebenza kakuhle kokuguqulwa kwamandla
③Uxinzelelo oluphezulu lobushushu kunye nobomi obuncitshisiweyo benkqubo
④Umngcipheko ophezulu womonakalo wamehlo ngexesha lokusebenza
Ke ngoko, ukufikelela kwindawo efanayo ekusasazweni kokukhanya kwepompo yinjongo ebalulekileyo yobugcisa kuyilo lwemodyuli yepompo kunye nokuveliswa kwayo.
2. Izizathu Eziqhelekileyo Zokusasazwa Kwenzuzo Engalinganiyo
①Iinguqu kwi-Chip Emission Power
Iitships ze-laser diode zibonisa utshintsho lwamandla ngokwemvelo. Ngaphandle kokuhlelwa okanye ukubuyiselwa ngokufanelekileyo, olu mahluko lunokukhokelela kumandla epompo angaguquguqukiyo kwindawo ekujoliswe kuyo.
②Iimpazamo kwiinkqubo zeCollimation kunye neFocusing
Ukungalungelelani okanye iziphene kwizakhi ze-optical (umz., iilensi ze-FAC/SAC, ii-microlens arrays, ii-fiber couplers) kunokubangela ukuba iindawo zomqadi ziphambuke kwindawo ekujoliswe kuyo, nto leyo edala iindawo ezishushu okanye iindawo ezifileyo.
③Iziphumo zeGradient yobushushu
Iileyiza ze-semiconductor zinovelwano kakhulu kubushushu. Uyilo olubi lwe-heatsink okanye ukupholisa okungalinganiyo kunokubangela ukushukuma kwe-wavelength phakathi kweetships ezahlukeneyo, okuchaphazela ukusebenza kakuhle kwe-coupling kunye nokuhambelana kwemveliso.
④Uyilo lweFiber Output olunganelanga
Kwizakhiwo zemveliso ze-fiber-core okanye ezidibanisa imisebe, ulwakhiwo olungafanelekanga lwe-core lunokubangela ukusasazwa kokukhanya kwepompo okungafaniyo kwi-gain medium.
3. Iindlela zokuphucula ukuFumana ukufana
①Ukuhlela iitshiphusi kunye nokufanisa amandla
Hlola ngokuchanekileyo kwaye uqokelele iitships ze-laser diode ukuqinisekisa amandla okukhupha afanayo kwimodyuli nganye, unciphise ubushushu obuphezulu bendawo kwaye ufumane iindawo ezishushu.
②Uyilo lwe-Optical oluLungileyo
Sebenzisa ii-optics ezingezizo ezomfanekiso okanye iilensi ezihambelanayo (umz., ii-microlens arrays) ukuphucula ukugqithana kwemitha kunye nokuchaneka kokugxila, ngaloo ndlela uthambise iprofayili yesibane sepompo.
③Ulawulo oluphuculweyo lobushushu
Sebenzisa izixhobo zokuqhuba ubushushu obuphezulu (umz., iCuW, idayimani yeCVD) kunye namaqhinga okulawula ubushushu afanayo ukunciphisa ukuguquguquka kobushushu be-chip-to-chip kunye nokugcina imveliso izinzile.
④Ukukhanya kwe-Homogenization yoBukhulu bokukhanya
Faka ii-diffusers okanye izinto ezibumba imiqadi ecaleni kwendlela yokukhanya kwepompo ukuze ufumane ukusasazwa kokukhanya okulinganayo ngaphakathi kwendawo yokuzuza.
4. Ixabiso Elisebenzayo kwiZicelo zeHlabathi lokwenyani
Kwiinkqubo zelaser eziphezulu—ezifana nokucubungula ngokuchanekileyo kwemizi-mveliso, ukutyunjwa kwe-laser yomkhosi, unyango, kunye nophando lwesayensi—uzinzo kunye nomgangatho wemitha ye-laser zibaluleke kakhulu. Ukusasazwa kwe-gain engalinganiyo kuchaphazela ngokuthe ngqo ukuthembeka kunye nokuchaneka kwenkqubo, ngakumbi kwezi meko zilandelayo:
①I-laser ezisebenzisa amandla aphezulu: Iphepha ukugcwala kwendawo okanye iziphumo ezingezizo ze-linear
②Ii-amplifiers ze-laser zefayibha: Zithintela ukwakheka kwe-ASE (Amplified Spontaneous Emission)
③Iinkqubo ze-LIDAR kunye ne-rangefinding: Ziphucula ukuchaneka kokulinganisa kunye nokuphindaphinda
④I-laser zonyango: Iqinisekisa ulawulo oluchanekileyo lwamandla ngexesha lonyango
5. Isiphelo
Ukufana kokusasazwa kwe-Gain kusenokungabi yeyona parameter ibonakalayo yemodule yepompo, kodwa kubalulekile ekunikezeni amandla ngokuthembekileyo kwiinkqubo ze-laser ezisebenzayo. Njengoko iimfuno zomgangatho we-laser kunye nozinzo ziqhubeka zisanda, abavelisi bemodule yepompo kufuneka baphathe“ulawulo lokufana"njengenkqubo ephambili—Ukucoca rhoqo ukukhethwa kweetshiphusi, uyilo lwesakhiwo, kunye namaqhinga obushushu ukuze kunikezelwe imithombo yelaser ethembekileyo nengaguquguqukiyo kwizicelo ezisezantsi.
