I-Lumispot Technology Co., Ltd., ngokusekelwe eminyakeni yocwaningo nentuthuko, ithuthukise ngempumelelo usayizi omncane nesisindo esincane esinama-pulsed laser enamandla angu-80mJ, imvamisa yokuphindaphinda engu-20 Hz kanye nobude obuphephile beso bomuntu obungu-1.57μm. Lo mphumela wocwaningo ufinyelelwe ngokukhuphula ukusebenza kahle kwengxoxo kwe-KTP-OPO nokuthuthukisa okukhiphayo kwemojula yelaser ye-pump diode laser. Ngokomphumela wokuhlolwa, le laser ihlangabezana nemfuneko ebanzi yokusebenza kwezinga lokushisa ukusuka ku -45 ℃ kuya ku-65 ℃ ngokusebenza okuhle kakhulu, ifinyelela ezingeni eliphakeme e-China.
I-Pulsed Laser Rangefinder iyithuluzi lokulinganisa ibanga ngenzuzo ye-laser pulse eqondiswe kokuqondisiwe , ngokufaneleka kwekhono lokuthola uhla lokunemba okuphezulu, ikhono eliqinile lokulwa nokuphazamiseka kanye nesakhiwo esihlangene. Umkhiqizo usetshenziswa kakhulu ekukaleni ubunjiniyela nakweminye imikhakha. Le pulsed laser rangefinding indlela isetshenziswa kakhulu ekusetshenzisweni kokulinganisa ibanga elide. Kulesi sitholi sebanga elide, kungcono kakhulu ukukhetha i-laser yesimo esiqinile enamandla amakhulu kanye ne-engeli encane yokuhlakazeka kwe-beam, kusetshenziswa ubuchwepheshe bokushintsha i-Q ukuze kukhishwe ama-nanosecond laser pulses.
Izitayela ezifanele ze-pulsed laser rangefinder zimi kanje:
(1) I-Human Eye-safe Laser Rangefinder:1.57um oscillator optical parametric oscillator kancane kancane ithatha isikhundla se-laser rangefinder evamile engu-1.06um kuningi lezinkambu zokuthola ububanzi.
(2) I-Miniaturized Remote Laser Rangefinder enosayizi omncane nesisindo esilula.
Ngokuthuthukiswa kokutholwa nokusebenza kwesistimu yokuthwebula, izitholi ze-laser ezikude ezikwazi ukukala okuqondiwe okuncane okungu-0.1m² ngaphezu kuka-20 km ziyadingeka. Ngakho-ke, kuyaphuthuma ukufunda i-laser rangefinder esebenza kahle kakhulu.
Eminyakeni yakamuva, i-Lumispot Tech yenze umzamo ocwaningweni, ekuklameni, ekukhiqizeni nasekudayiseni i-laser yesimo esiqinile ye-wavelength engu-1.57um ene-engeli encane yokuhlakazeka kwe-boam kanye nokusebenza okuphezulu kokusebenza.
Muva nje, i-Lumispot Tech, iklame i-laser epholile engu-1.57um ye-wavelength air ephephile enamandla aphezulu kanye nesakhiwo esihlangene, okubangelwa isidingo esingokoqobo phakathi kocwaningo lwe-minization yebanga elide le-laser rangefinder,.Ngemva kokuhlolwa, le laser ibonisa ububanzi. amathemba ohlelo lokusebenza, abe nokusebenza okuhle kakhulu, ukuguquguquka okuqinile kwemvelo ngaphansi kwebanga elibanzi lokushisa lokusebenza ukusuka -40 kuya ku-65 degree celsius,
Ngokusebenzisa isibalo esilandelayo, nenani elinqunyiwe lesinye isithenjwa, ngokuthuthukisa amandla okukhiphayo aphezulu nokunciphisa i-engeli yokuhlakaza ye-beam, ingathuthukisa ibanga lokulinganisa lesitholi sebanga. Njengomphumela, izici ezi-2: inani lamandla okukhipha isiqongo kanye ne-laser yesakhiwo esihlangene se-engeli ehlakazekayo esisebenza komoya siyingxenye ebalulekile enquma ikhono lokulinganisa ibanga lesitholi sendawo esithile.
Ingxenye ebalulekile yokuqaphela i-laser enobude begagasi obuvikeleke ngeso lomuntu yindlela ye-optical parametric oscillator (OPO), ehlanganisa inketho yekristalu engaqondile, indlela yokufanisa isigaba kanye nedizayini yesakhiwo se-OPO interiol. Ukukhethwa kwekristalu engaqondile kuncike ku-coefficient enkulu engaqondile, umkhawulo ophezulu wokumelana nomonakalo, izakhiwo ezinzile zamakhemikhali nezomzimba kanye namasu okukhula okuvuthiwe njll., ukufaniswa kwesigaba kufanele kuze kuqala. Khetha indlela yokumatanisa yesigaba engabalulekile ene-engeli enkulu yokwamukela kanye ne-engeli encane yokusuka; Isakhiwo somgodi we-OPO kufanele sicabangele ukusebenza kahle kanye nekhwalithi ye-beam esisekelweni sokuqinisekisa ukwethembeka.ijika elishintshayo le-KTP-OPO ye-wavelength ephumayo ene-engeli yokufanisa isigaba, lapho θ=90°, ukukhanya kwesignali kungakhipha iso lomuntu ngokuphephile. laser. Ngakho-ke, ikristalu eklanyelwe isikwa eceleni kolunye uhlangothi, ukufanisa i-engeli kusetshenziswa θ=90°，φ=0°, okungukuthi, ukusetshenziswa kwendlela yokufanisa ikilasi, lapho i-crystal coefficient engasebenzi engasebenzi kahle inkulu futhi ungekho umphumela wokuhlakazeka. .
Ngokusekelwe ekucatshangelweni okuphelele kwalolu daba olungenhla, kuhlanganiswe nezinga lokuthuthuka lendlela yokusebenza ye-laser yasekhaya kanye nezinto zokusebenza, isisombululo sobuchwepheshe sokuthuthukisa yilesi: I-OPO yamukela isigaba sesibili esingabalulekile esimatanisa umgodi wangaphandle we-dual-cavity KTP-OPO. ukuklama; ama-KTP-OPO angu-2 enzeke mpo esakhiweni se-tandem ukuze kuthuthukiswe ukusebenza kahle kokuguqulwa nokuthembeka kwe-laser njengoba kuboniswe ku-Umfanekiso 1Ngenhla.
Umthombo wephampu wucwaningo oluzicwaningayo futhi oluthuthukisiwe lwe-laser ye-semiconductor epholile epholile, enomjikelezo womsebenzi ongu-2% okungenani, amandla aphezulu angu-100W webha eyodwa kanye namandla okusebenza angu-12,000W. Iprism ye-engeli yesokudla, i-planar all-reflective mirror kanye ne-polarizer yakha i-polarization egoqiwe ehambisana nokuphumayo kwe-resonant cavity, kanye ne-prism ye-engeli engakwesokudla ne-waveplate kuyazungezwa ukuze kutholwe okukhiphayo okudingwayo kwe-laser engu-1064 nm. Indlela yokushintshashintsha kwe-Q iwukuguquguquka okucindezelwe okusebenzayo kwe-electro-optical Q okusekelwe kukristalu lwe-KDP.

Umfanekiso 2: Imodyuli yebha emise okwe-arc ngokuzithuthukisa,
ngenduku yekristalu ye-YAG phakathi.
IUmfanekiso 2izitaki zebha ezimise okwe-arc, ezibeka izinti zekristalu ye-YAG njengendawo ephakathi ye-laser ngaphakathi kwemojuli, ngokugxila okungu-1%. Ukuze kuxazululwe ukungqubuzana phakathi kokunyakaza kwe-laser yangemuva kanye nokusatshalaliswa kwe-symmetric kokuphuma kwe-laser, kwasetshenziswa ukusabalalisa okulinganayo kwamalungu afanayo e-LD nge-engeli engu-120 degrees. Umthombo wephampu ungu-1064nm wavelength, amamojula amabili we-array egobile angu-6000W ochungechungeni lokumpompa kwe-semiconductor tandem. Amandla okukhiphayo angu-0-250mJ anobubanzi beshayela obungaba ngu-10ns kanye nemvamisa esindayo engu-20Hz. kusetshenziswa umgodi ogoqiwe, futhi i-laser ye-wavelength engu-1.57μm iphuma ngemva kwekristalu ye-tandem ye-KTP engaqondile.
Igrafu 3Umdwebo wohlangothi we-1.57um wavelength pulsed laser
Igrafu 4:1.57um wavelength pulsed laser isampula imishini
Igrafu 5:1.57μm okukhiphayo
Igrafu 6:Ukusebenza kahle kokuguqulwa komthombo wephampu
Ukujwayela i-laser energy measuremnt ukuze kukale amandla okukhiphayo ezinhlobo ezi-2 zamaza amaza ngokulandelanayo. Ngokwegrafu eboniswe ngezansi, ukubuyiselwa kwevelu yamandla kwakuyinani elimaphakathi elisebenza ngaphansi kuka-20Hz neminithi elingu-1 lesikhathi sokusebenza. Phakathi kwazo, amandla akhiqizwe yi-laser ye-wavelenth engu-1.57um anoshintsho olusheshayo nobudlelwano be-1064nm wavelength umthombo wamandla wephampu. Uma amandla omthombo wephampu elingana no-220mJ, amandla okukhiphayo e-laser engu-1.57um wavelength akwazi ukuzuza u-80mJ, ngezinga lokuguqulwa elifika ku-35%. Njengoba ukukhanya kwesignali ye-OPO kukhiqizwa ngaphansi kwesenzo sokuminyana kwamandla athile wokukhanya okuvamisile okuyisisekelo, inani layo le-threshold lingaphezulu kwevelu ye-threshold engu-1064 nm yokukhanya okuyisisekelo kwefrikhwensi, futhi amandla ayo okukhiphayo akhula ngokushesha ngemva kokuba amandla okupompa edlula inani le-OPO threshold value. . Ubudlelwano phakathi kwamandla okukhiphayo kwe-OPO nokusebenza kahle ngamandla ayisisekelo okukhipha ukukhanya kwefrikhwensi kuboniswa esibalweni, lapho kungabonwa khona ukuthi ukusebenza kahle kokuguqulwa kwe-OPO kungafinyelela ku-35%.
Ekugcineni, ukuphuma kwe-laser ye-wavelength engu-1.57μm enamandla amakhulu kuno-80mJ kanye nobubanzi be-laser pulse obungu-8.5ns kungafinyelelwa. i-engeli ehlukanisiwe ye-laser beam ephumayo nge-expander ye-laser beam ngu-0.3mrad. ukulingisa nokuhlaziya kubonisa ukuthi amandla okulinganisa ububanzi be-pulsed laser rangefinder esebenzisa le laser angadlula ama-30km.
