Kwizicelo ze-laser yemizi-mveliso, i-diode pumping laser module isebenza njenge "power core" yenkqubo ye-laser. Ukusebenza kwayo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kokucubungula, ubomi bezixhobo, kunye nomgangatho wokugqibela wemveliso. Nangona kunjalo, ngeentlobo ezahlukeneyo ze-diode pumping laser ezikhoyo kwimarike (ezifana neentlobo ze-end-pumped, side-pumped, kunye ne-fiber-coupled), umntu angazifanisa njani ngokuchanekileyo iimfuno ezithile zoshishino? Eli nqaku libonelela ngesicwangciso sokukhetha esicwangcisiweyo esisekelwe kwiiparameter zobugcisa kunye nohlalutyo olusekelwe kwimeko.
1. Chaza iiMfuno eziPhambili zeSicelo seShishini
Ngaphambi kokukhetha imodyuli yelaser yokupompa idiode, kubalulekile ukucacisa iiparameter eziphambili zemeko yesicelo:
① Uhlobo Lokucubungula
- Ukucubungula okuqhubekayo okunamandla aphezulu (umz., ukusika/ukuwelda isinyithi esityebileyo): Beka phambili uzinzo lwamandla (>1kW) kunye nokukwazi ukusasaza ubushushu.
- Umatshini wokulungisa izinto ochanekileyo (umz., ukubhola/ukugrumba izinto ezibuthathaka): Ifuna umgangatho ophezulu we-beam (M² < 10) kunye nolawulo oluchanekileyo lwe-pulse (inqanaba le-nanosecond). – Ukucubungula ngesantya esiphezulu (umz., ukuwelda ithebhu yebhetri ye-lithium): Ifuna amandla okuphendula ngokukhawuleza (isantya sokuphindaphinda kuluhlu lwe-kHz). ② Ukuguquguquka kwendalo – Iindawo ezinobungozi (umz., ubushushu obuphezulu, uthuli, ukungcangcazela okufana nemigca yemveliso yeemoto): Ifuna inqanaba eliphezulu lokhuseleko (IP65 okanye ngaphezulu) kunye noyilo olumelana nokutsha. ③ Iingqwalasela zeendleko zexesha elide Izixhobo zoshishino zihlala zisebenza iiyure ezingama-24 ngosuku, ngoko ke kubalulekile ukuvavanya ukusebenza kakuhle kwe-electro-optical (>30%), imijikelo yolondolozo, kunye neendleko zenxalenye eseleyo.
2. Izalathisi Zokusebenza Eziphambili Zichaziwe
① Amandla okuphuma kunye nomgangatho weBeam
- Uluhlu lwaMandla: Iimodyuli zelaser zokupompa idiode yomgangatho wezoshishino zihlala ziqala kwi-100W ukuya kwi-10kW. Khetha ngokusekelwe kubukhulu bezinto (umz., ukusika intsimbi engama-20mm kufuna ≥3kW).
- Umgangatho weBeam (M² Factor):
- M² < 20: Ifanelekile ukucutshungulwa ngokurhabaxa (umz., ukucocwa komphezulu).
- M² < 10: Ifanelekile ukuwelda/ukusika ngokuchanekileyo (umz., intsimbi engatyiwayo eyi-0.1mm). – Qaphela: Amandla aphezulu adla ngokuphazamisa umgangatho wemitha; cinga ngoyilo lokumpompa olusebenzisa i-side-pumped okanye olusebenzisa i-hybrid ukuze luphuculwe. ② Ukusebenza kakuhle kwe-Electro-Optical kunye noLawulo lobushushu – Ukusebenza kakuhle kwe-Electro-Optical: Ichaphazela ngokuthe ngqo iindleko zamandla. Iimodyuli ezinokusebenza kakuhle okungaphezulu kwama-40% ziyathandwa (umz., iimodyuli ze-laser zokumpompa i-diode zisebenza kakuhle ngokuphindwe ka-2-3 kunezo zisetyenziswa ngezibane zemveli).
- Uyilo Lokupholisa: Ukupholisa ulwelo lwe-Microchannel (ukusebenza kakuhle kokupholisa >500W/cm²) kulungele ngakumbi ukusebenza ixesha elide, umthwalo omninzi kunokupholisa umoya.
③ Ukuthembeka kunye nexesha lokuphila
- I-MTBF (Ixesha Eliphakathi Phakathi Kokusilela): Iindawo zoshishino zifuna iiyure ezingaphezu kwama-50,000.
- Ukumelana nongcoliseko: Umngxuma obonakalayo ovaliweyo uthintela ukutshiza kwesinyithi kunye nokungena kothuli (umgangatho we-IP67 ungcono nangakumbi).
④ Ukuhambelana kunye nokukhula
- Ujongano loLawulo: Inkxaso yeenkqubo zoshishino ezifana ne-EtherCAT kunye ne-RS485 yenza kube lula ukuhlanganiswa kwimigca yemveliso ezenzekelayo.
- Ukwandiswa kweModular: Inkxaso yoqwalaselo oluhambelanayo lweemodyuli ezininzi (umz., ukubekwa kwe-6-in-1 stacking) ivumela ukuphuculwa kwamandla ombane okungenamthungo.
⑤ Ubude beWave kunye nePlulse Characters
- Ukulinganisa ubude bamaza:
- 1064nm: Iqhelekile ekucutshungulweni kwesinyithi.
- 532nm/355nm: Ifanelekile ukucutshungulwa ngokuchanekileyo kwezinto ezingezizo ezesinyithi ezifana neglasi kunye neeseramikhi.
- Ulawulo lwePulse:
- Imo ye-QCW (Quasi-Continuous Wave) ifanelekile kwiindlela ezisebenzisa amandla aphezulu, ezisebenzisa amaza aphantsi (umz., ukukrola okunzulu).
- Ukuphindaphinda okuphezulu (inqanaba le-MHz) kufanelekile kumakishwa ngesantya esiphezulu.
3. Ukuphepha Iingxaki Zokukhetha Eziqhelekileyo
- Ingxaki 1: “Okukhona amandla ephezulu, kokukhona ngcono” – Amandla agqithisileyo anokubangela ukutsha kwezinto. Linganisa amandla kunye nomgangatho wemitha.
- Ingxaki 2: “Ukungazinaki iindleko zolondolozo lwexesha elide” – Iimodyuli ezingasebenzi kakuhle zinokubangela amandla aphezulu kunye neendleko zolondolozo ngokuhamba kwexesha, zigqithise ukonga kokuqala.
- Ingxaki 3: “Imodyuli yobukhulu obunye ifanela zonke iimeko” – Ukuchaneka kunye nokucubungula okuqinileyo kufuna uyilo olwahlukileyo (umz., uxinaniso lwe-doping, ulwakhiwo lwepompo).
