I-Lumispot Technology Co., Ltd., ngokusekelwe eminyakeni yocwaningo nentuthuko, ithuthukise ngempumelelo i-laser encane nesisindo esincane eshukunyiswayo enamandla angu-80mJ, imvamisa yokuphindaphinda engu-20 Hz kanye nobude be-wavelength obuphephile emehlweni abantu obungu-1.57μm. Lo mphumela wocwaningo ufezwe ngokwandisa ukusebenza kahle kwengxoxo ye-KTP-OPO kanye nokwenza ngcono umkhiqizo we-module ye-laser ye-diode yomthombo wephampu. Ngokusho komphumela wokuhlolwa, le laser ihlangabezana nezidingo zokushisa okubanzi zokusebenza kusukela ku--45 ℃ kuya ku-65 ℃ ngokusebenza okuhle kakhulu, ifinyelela ezingeni eliphakeme eShayina.
I-Pulsed Laser Rangefinder iyithuluzi lokulinganisa ibanga ngenxa yenzuzo ye-laser pulse eqondiswe kuthagethi, enezinzuzo zekhono lokuthola ububanzi elinembile kakhulu, ikhono elinamandla lokulwa nokuphazamiseka kanye nesakhiwo esincane. Umkhiqizo usetshenziswa kabanzi ekulinganisweni kobunjiniyela nakwezinye izinkambu. Le ndlela yokuthola ububanzi be-laser pulsed isetshenziswa kakhulu ekusetshenzisweni kokulinganisa ibanga elide. Kulesi sigaba sokuthola ububanzi bebanga elide, kungcono kakhulu ukukhetha i-solid-state laser enamandla aphezulu kanye ne-angle encane yokusabalalisa imisebe, kusetshenziswa ubuchwepheshe be-Q-switching ukukhipha ama-pulse e-laser e-nanosecond.
Izitayela ezifanele ze-pulsed laser rangefinder yilezi ezilandelayo:
(1) I-Laser Rangefinder ephephile emehlweni omuntu: i-oscillator ye-parametric ye-optical engu-1.57um ithatha indawo ye-rangefinder ye-laser rangefinder yendabuko engu-1.06um wavelength ezindaweni eziningi zokuthola ububanzi.
(2) I-Miniaturized Remote Laser Rangefinder enosayizi omncane futhi elula.
Ngokuthuthuka kokusebenza kohlelo lokuthola nokuthola izithombe, kudingeka ama-rangefinder e-laser akude akwazi ukulinganisa ama-target amancane angu-0.1m² ngaphezu kwamakhilomitha angama-20. Ngakho-ke, kuyaphuthuma ukutadisha i-rangefinder ye-laser esebenza kahle kakhulu.
Eminyakeni yamuva nje, i-Lumispot Tech ifake umzamo wokucwaninga, ukuklama, ukukhiqizwa kanye nokuthengiswa kwe-laser eqinile yesimo esiqinile engu-1.57um wavelength ene-angle encane yokusabalala kwemisebe kanye nokusebenza okuphezulu kokusebenza.
Muva nje, i-Lumispot Tech, iklame i-laser epholile emoyeni engu-1.57um ephephile emehlweni enamandla aphezulu kanye nesakhiwo esincane, okubangelwa isidingo esisebenzayo ocwaningweni lwe-laser rangefinder ende encishisiwe. Ngemuva kokuhlolwa, le laser ikhombisa amathuba amaningi okusetshenziswa, inamandla amahle kakhulu, iyakwazi ukuzivumelanisa nezimo zemvelo ngaphansi kobubanzi bokushisa kokusebenza obuvela ku--40 kuya ku-65 degrees celsius,
Ngalesi sibalo esilandelayo, ngenani elinqunyiwe lezinye izinkomba, ngokuthuthukisa amandla okukhipha okuphezulu nokunciphisa i-angle yokusabalala kwe-beam, kungathuthukisa ibanga lokulinganisa le-rangefinder. Ngenxa yalokho, izici ezimbili: inani lamandla okukhipha okuphezulu kanye ne-angle yokusabalala kwe-beam encane i-laser yesakhiwo esihlanganisiwe enomsebenzi opholile emoyeni yingxenye ebalulekile enquma ikhono lokulinganisa ibanga le-rangefinder ethile.
Ingxenye ebalulekile yokwenza i-laser ibe nobude be-wavelength obuphephile emehlweni omuntu inqubo ye-optical parametric oscillator (OPO), okuhlanganisa inketho yekristalu engeyona eqondile, indlela yokufanisa isigaba kanye nomklamo wesakhiwo se-OPO interiol. Ukukhetha ikristalu engeyona eqondile kuncike ku-coefficient enkulu engeyona eqondile, umkhawulo wokumelana komonakalo omkhulu, izakhiwo zamakhemikhali ezizinzile kanye nezindlela zokukhula ezivuthiwe njll., ukufaniswa kwesigaba kufanele kuthathe indawo yokuqala. Khetha indlela yokufanisa isigaba engeyona ebucayi ene-engeli enkulu yokwamukela kanye ne-engeli encane yokusuka; Isakhiwo se-cavity ye-OPO kufanele sicabangele ukusebenza kahle kanye nekhwalithi ye-beam ngokusekelwe ekuqinisekiseni ukuthembeka. Ijika lokushintsha le-wavelength yokukhipha ye-KTP-OPO ene-engeli yokufanisa isigaba, lapho i-θ=90°, ukukhanya kwesignali kungakhipha ngqo i-laser ephephile amehlo omuntu. Ngakho-ke, ikristalu eklanyelwe inqunywa ohlangothini olulodwa, ukufaniswa kwe-engeli kusetshenziswa i-θ=90°，φ=0°, okungukuthi, ukusetshenziswa kwendlela yokufanisa isigaba, lapho i-coefficient engeyona eqondile esebenza ngekristalu inkulu kakhulu futhi kungekho mphumela wokuhlakazeka.
Ngokusekelwe ekucabangeni okubanzi kwalolu daba olungenhla, kuhlanganiswe nezinga lokuthuthukiswa kobuchwepheshe be-laser yasekhaya kanye nemishini yamanje, ikhambi lobuchwepheshe lokwenza ngcono yileli: I-OPO isebenzisa umklamo we-KTP-OPO wesigaba II ongeyona into ebalulekile yokufanisa isigaba sangaphandle; ama-KTP-OPO amabili aqondile esakhiweni se-tandem ukuthuthukisa ukusebenza kahle kokuguqulwa kanye nokuthembeka kwe-laser njengoba kuboniswe kuUmfanekiso 1Ngaphezulu.
Umthombo wephampu uwucwaningo oluzimele noluthuthukiswe nge-conductive cooled semiconductor laser array, enomjikelezo womsebenzi ongu-2% okungenani, amandla aphezulu angu-100W webha eyodwa kanye namandla okusebenza aphelele angu-12,000W. I-prism ye-angle engakwesokudla, isibuko esikhanyayo esiphelele kanye ne-polarizer kwakha i-polarization coupled output resonant cavity, kanti i-prism ye-angle engakwesokudla kanye ne-waveplate kuyajikeleziswa ukuze kutholakale umphumela ofunwayo wokuxhumanisa i-laser ongu-1064 nm. Indlela ye-Q modulation iwukuguquguquka kwe-Q okusebenzayo okucindezelwe okusekelwe kukristalu ye-KDP.

Umfanekiso 2: Imojula ye-bar array enomumo we-arc nge-self-development,
nenduku yekristalu ye-YAG phakathi.
IUmfanekiso 2yizinqwaba zebha ezimise okwe-arc, ezibeka izinduku zekristalu ze-YAG njenge-laser medium ngaphakathi kwemojuli, ngokuhlushwa okungu-1%. Ukuxazulula ukungqubuzana phakathi kokunyakaza kwe-laser eseceleni kanye nokusatshalaliswa okulinganayo kokukhishwa kwe-laser, kwasetshenziswa ukusatshalaliswa okulinganayo kwe-LD array nge-engeli yama-degrees angu-120. Umthombo wephampu ungama-wavelength angu-1064nm, amamojula amabili ebha yebha ye-array egobile angu-6000W ku-series semiconductor tandem pumping. Amandla okukhipha angu-0-250mJ anobubanzi be-pulse obungaba ngu-10ns kanye nemvamisa enzima engu-20Hz. kusetshenziswa i-cavity egoqiwe, kanti i-laser ye-wavelength engu-1.57μm ikhishwa ngemuva kwe-tandem KTP nonlinear crystal.
Igrafu 3Umdwebo olinganiselayo we-laser evunguzayo engu-1.57um wavelength
Igrafu 4: 1.57um wavelength imishini yesampula ye-laser eshaywayo
Igrafu 5:Umphumela ongu-1.57μm
Igrafu 6:Ukusebenza kahle kokuguqulwa komthombo wephampu
Ukuvumelanisa ukulinganisa amandla e-laser ukuze kulinganiswe amandla okukhipha ezinhlobo ezimbili zobude be-wavelength ngokulandelana. Ngokusho kwegrafu eboniswe ngezansi, inani lamandla eliphindaphindwayo laliyinani elimaphakathi elisebenza ngaphansi kwe-20Hz nesikhathi sokusebenza esingumzuzu owodwa. Phakathi kwazo, amandla akhiqizwa yi-laser ye-wavelength engu-1.57um anoshintsho oluhambisanayo nobudlelwano bamandla omthombo wephampu ye-wavelength engu-1064nm. Uma amandla omthombo wephampu elingana no-220mJ, amandla okukhipha e-laser ye-wavelength engu-1.57um akwazi ukufinyelela ku-80mJ, kanti izinga lokuguqulwa lifinyelela ku-35%. Njengoba ukukhanya kwesignali ye-OPO kukhiqizwa ngaphansi kwesenzo samandla athile okukhanya kwemvamisa eyisisekelo, inani layo lomkhawulo liphakeme kunenani lomkhawulo lokukhanya kwemvamisa eyisisekelo engu-1064 nm, futhi amandla okukhipha ayanda ngokushesha ngemva kokuba amandla okupompa edlula inani lomkhawulo we-OPO. Ubudlelwano phakathi kwamandla okukhipha i-OPO kanye nokusebenza kahle kwamandla okukhipha ukukhanya okujwayelekile okuyisisekelo kuboniswa esithombeni, lapho kungabonakala khona ukuthi ukusebenza kahle kokuguqulwa kwe-OPO kungafinyelela ku-35%.
Ekugcineni, kungafinyelelwa umphumela we-laser pulse ongu-1.57μm wavelength onamandla angaphezu kuka-80mJ kanye nobubanzi be-laser pulse obungu-8.5ns. I-engeli yokwehluka komsebe we-laser ophumayo nge-laser beam expander ingu-0.3mrad. Ukulingisa nokuhlaziya kukhombisa ukuthi ikhono lokulinganisa ububanzi be-pulsed laser rangefinder esebenzisa le laser lingadlula amakhilomitha angu-30.
