I-Lumispot Technology Co., Ltd., esekelwe kwiminyaka yophando kunye nophuhliso, iphuhlise ngempumelelo ubungakanani obuncinci kunye nesisindo sokukhanya kwe-laser ye-pulsed ene-80mJ, ukuphindaphinda ukuphindaphinda kwe-20 Hz kunye ne-wavelength ekhuselekileyo yamehlo yomntu ye-1.57μm.Esi siphumo sophando siphunyezwe ngokunyusa ukusebenza kakuhle kwencoko ye-KTP-OPO kunye nokwandisa imveliso yemodyuli yomthombo wempompo ye-diode laser.Ngokwesiphumo sovavanyo, le laser ihlangabezana nemfuneko yobushushu obusebenzayo ukusuka kwi -45 ℃ ukuya kuma-65 ℃ ngokusebenza okugqwesileyo, ukufikelela kwinqanaba eliphezulu eTshayina.
I-Pulsed Laser Rangefinder sisixhobo sokulinganisa umgama ngenzuzo ye-laser pulse ejoliswe ekujoliswe kuyo, kunye nokufaneleka kobuchule bokufumana uluhlu oluchanekileyo oluchanekileyo, amandla anamandla okuchasana nokuphazamiseka kunye nesakhiwo esihlangeneyo.Imveliso isetyenziswa ngokubanzi kumlinganiselo wobunjineli kunye neminye imimandla.Le ndlela yokufumana uluhlu lwe-laser ye-pulsed isetyenziswa kakhulu ekusetyenzisweni komlinganiselo womgama omde.Kolu luhlu lomgama omde, kukhethwa ngakumbi ukukhetha i-laser-state eqinile enamandla amakhulu kunye ne-angle encinci yokuchithwa kwe-boam, usebenzisa i-Q-switching iteknoloji ukuvelisa i-nanosecond laser pulses.
Iintsingiselo ezifanelekileyo ze-pulsed laser rangefinder zezi zilandelayo:
(1) I-Laser Rangefinder ye-Laser ekhuselekileyo yamehlo:1.57um i-oscillator yeparametric optical ngokuthe ngcembe ithathela indawo indawo yesiqhelo ye-1.06um wavelength laser rangefinder kuninzi lweenkalo zokufumana uluhlu.
(2) I-Miniaturized Remote Laser Rangefinder enobungakanani obuncinci kunye nobunzima obulula.
Ngophuculo lokuchongwa kunye nokusebenza kwenkqubo yomfanekiso, ii-remote laser rangefinders ezikwaziyo ukulinganisa iithagethi ezincinci ze-0.1m² ngaphezulu kwe-20 km ziyafuneka.Ke ngoko, kungxamisekile ukufunda i-laser rangefinder esebenza kakhulu.
Kwiminyaka yakutshanje, iLumispot Tech ibeke umzamo kuphando, uyilo, imveliso kunye nokuthengiswa kwe-1.57um wavelength iliso elikhuselekileyo le-laser yemeko eqinileyo ene-angle encinci yokuchithachitha kunye nokusebenza okuphezulu.
Kutshanje, iLumispot Tech, iyile i-1.57um eye-wavelength emoyeni epholileyo yelaser enamandla aphezulu aphezulu kunye nesakhiwo esibambeneyo, esiphuma kwimfuno ebonakalayo ngaphakathi kophando lwe-minization yomgama omde we-laser rangefinder, emva kovavanyo, le laser ibonisa ububanzi. Amathuba okusebenza, asebenza kakuhle, ukuguquguquka okuqinileyo kokusingqongileyo phantsi koluhlu olubanzi lobushushu bokusebenza ukusuka kwi-40 ukuya kuma-65 degrees celsius,
Ngokusebenzisa le equation ilandelayo, kunye nesixa esimiselweyo sesinye ireferensi, ngokuphucula amandla emveliso encopho kunye nokunciphisa i-angle yokuchithachitha umqadi, inokuphucula umgama wokulinganisa we- rangefinder.Ngenxa yoko, izinto ezi-2: ixabiso lencopho yemveliso yamandla kunye ne-angle encinci yokuchithachitheka kwe-angle i-compact compact laser enomsebenzi opholileyo ngomoya yinxalenye ephambili yokwenza isigqibo somlinganiselo womgama we-rangefinder ethile.
Inxalenye ephambili yokuqonda i-laser kunye ne-wavelength ekhuselekileyo yamehlo yomntu yi-optical parametric oscillator (OPO) ubuchule, kubandakanywa nokukhethwa kwekristale engabonakaliyo, indlela yokulinganisa isigaba kunye noyilo lwesakhiwo se-OPO interiol.Ukukhethwa kwe-crystal engabonakaliyo kuxhomekeke kwi-coefficient enkulu engabonakaliyo, i-ressiance threshold yomonakalo omkhulu, iikhemikhali ezizinzile kunye neempawu ezibonakalayo kunye nobuchule bokukhula obuvuthiweyo njl.Khetha indlela ehambelana nesigaba esingabalulekanga kunye ne-angle enkulu yokwamkelwa kunye ne-angle yokuhamba encinci;Isakhiwo somgodi we-OPO kufuneka sithathele ingqalelo ukusebenza kakuhle kunye nomgangatho we-beam kwisiseko sokuqinisekisa ukuthembeka.Ijiko lokutshintsha kwe-KTP-OPO ye-wavelength ephumayo kunye ne-angle ehambelana nesigaba, xa i-θ=90 °, ukukhanya komqondiso kunokukhupha ngqo iliso lomntu likhuselekile. laser.Ke ngoko, ikristale eyiliweyo inqunyulwe ecaleni kwelinye icala, i-angle ehambelanayo isetyenzisiwe θ=90 °，φ=0 °, oko kukuthi, ukusetyenziswa kwendlela yokulinganisa iklasi, xa i-crystal esebenzayo engahambelaniyo i-coefficient inkulu kwaye akukho siphumo sokusasazeka. .
Ngokusekwe kuqwalaselo olubanzi lwalo mba ungentla, kudityaniswe nenqanaba lophuhliso lobuchule belaser yasekhaya yangoku kunye nezixhobo, isisombululo sobuchule sokuphucula kukuba: I-OPO yamkela iClass II engeyomfuneko-isigaba esihambelana necavity yangaphandle ye-KTP-OPO. uyiloI-2 KTP-OPOs zenzeke ngokuthe nkqo kwisakhiwo se-tandem ukuphucula uguqulo olusebenzayo kunye nokuthembeka kwelaser njengoko kubonisiweUmfanekiso woku-1Ngaphezulu.
Umthombo wempompo luphando oluzenzelayo kunye nophuhliso lwe-laser ye-semiconductor epholileyo epholileyo, kunye nomjikelo womsebenzi we-2% ubukhulu becala, amandla encopho ye-100W kwibha enye kunye namandla okusebenza ewonke e-12,000W.Iprism ene-engile yasekunene, iplani yesipili esibonakalisa yonke into kunye ne-polarizer zenza i-polarization egotyiweyo edityaniswe ne-resonant cavity, kunye ne-prism ye-right-angle kunye ne-waveplate zijikeleziswa ukuze kufumaneke isiphumo esifunekayo se-1064 nm laser coupling.Indlela yokumodareyitha ye-Q yinkqubo yoxinzelelo esebenzayo ye-electro-optical Q esekelwe kwikristale ye-KDP.

Umfanekiso wesi-2: Imodyuli yoluhlu lwebha ye-arc ngokuziphuhlisa,
ngentonga yekristale ye-YAG embindini.
IUmfanekiso wesi-2yi-arc-shaped bar stacks, ebeka ii-crystals ze-YAG njenge-laser medium ngaphakathi kwimodyuli, kunye noxinzelelo lwe-1%.Ukusombulula ukuchasana phakathi kwentshukumo ye-laser ye-lateral kunye nokusabalalisa i-symmetric ye-laser output, ukuhanjiswa kwe-symmetric ye-LD kwi-angle ye-120 degrees isetyenziswe.Umthombo wempompo yi-1064nm ubude be-wavelength, iimodyuli ezimbini ze-6000W ezigobileyo zebar kuthotho lwe-semiconductor tandem pumping.Amandla aphumayo ngu-0-250mJ kunye nobubanzi be-pulse malunga ne-10ns kunye ne-frequency enzima ye-20Hz.kusetyenziswa umngxuma osongiweyo, kwaye i-laser ye-wavelength ye-1.57m iphuma emva kwekristale ye-tandem ye-KTP engabonakaliyo.

Igrafu 5:1.57μm imveliso
Igrafu 6:Ukusebenza kokuguqulwa komthombo wempompo
Ukulungelelanisa i-laser energy measuremnt ukulinganisa amandla emveliso yeentlobo ezi-2 zamaza ngokulandelelanayo.Ngokwegrafu eboniswe ngezantsi, ukubuyiswa kwexabiso lamandla kwakuyixabiso eliqhelekileyo elisebenza phantsi kwe-20Hz kunye ne-1 min ixesha lokusebenza.Phakathi kwabo, amandla aveliswa yi-1.57um wavelenth laser anotshintsho olukhawulezileyo kunye nobudlelwane be-1064nm wavelength umthombo wempompo yamandla.Xa amandla omthombo wempompo alingana ne-220mJ, amandla aphumayo we-1.57um wavelength laser akwazi ukufezekisa i-80mJ, kunye nesantya sokuguqulwa ukuya kuma-35%.Kuba ukukhanya kophawu lwe-OPO kuveliswa phantsi kwesenzo soxinzelelo oluthile lwamandla okukhanya okuhamba rhoqo, ixabiso layo lomda liphezulu kunexabiso lomqobo le-1064 nm yokukhanya okusisiseko kokukhanya, kwaye amandla ayo aphumayo anyuka ngokukhawuleza emva kokuba amandla okumpompa edlula ixabiso le-OPO. .Ubudlelwane phakathi kwemveliso ye-OPO yamandla kunye nokusebenza kakuhle kunye nesiseko samandla okukhutshwa kokukhanya okubonakalayo kuboniswa kumzobo, apho kunokubonwa ukuba ukuguqulwa kobuchule be-OPO kunokufikelela kwi-35%.
Ekugqibeleni, i-1.57μm ye-wavelength laser pulse output enamandla angaphezu kwe-80mJ kunye ne-laser pulse wide ye-8.5ns inokufezekiswa.i-angle yokuhlukana ye-output laser beam ngokusebenzisa i-laser beam expander yi-0.3mrad.Ukulinganisa kunye nohlalutyo lubonisa ukuba umthamo wokulinganisa uluhlu lwe-pulsed laser rangefinder usebenzisa le laser unokugqithisa i-30km.
