Lumispot Technology Co., Ltd., kutengera zaka za kafukufuku ndi chitukuko, idapanga bwino kakulidwe kakang'ono ndi kuwala kopepuka kwa laser yokhala ndi mphamvu ya 80mJ, kubwereza pafupipafupi kwa 20 Hz ndi kutalika kotetezedwa ndi maso kwamunthu kwa 1.57μm. Zotsatira za kafukufukuyu zidatheka pakukulitsa luso la zokambirana la KTP-OPO ndikukulitsa zotulutsa za module ya laser diode laser. Malinga ndi zotsatira zoyeserera, laser iyi imakumana ndi kutentha kwakukulu kogwira ntchito kuyambira -45 ℃ mpaka 65 ℃ ndikuchita bwino kwambiri, kufika pamlingo wapamwamba ku China.
Pulsed Laser Rangefinder ndi chida choyezera mtunda ndi mwayi wa laser pulse yolunjika kwa chandamale, chokhala ndi luso lapamwamba lapamwamba lofufuza bwino, luso lamphamvu loletsa kusokoneza komanso kapangidwe kake. Chogulitsacho chimagwiritsidwa ntchito kwambiri poyezera uinjiniya ndi magawo ena. Njira yopezera ma pulsed laser iyi imagwiritsidwa ntchito kwambiri poyezera mtunda wautali. Pazida zazitali izi, ndikwabwino kusankha laser yolimba kwambiri yokhala ndi mphamvu zambiri komanso ngodya yaying'ono yobalalika, pogwiritsa ntchito ukadaulo wa Q-switching kuti utulutse ma nanosecond laser pulses.
Njira zoyenera za pulsed laser rangefinder ndi izi:
(1) Human Diso-Safe Laser Rangefinder:1.57um optical parametric oscillator pang'onopang'ono ikulowa m'malo mwa 1.06um wavelength laser rangefinder m'magawo ambiri opeza.
(2) Miniaturized Remote Laser Rangefinder yokhala ndi kukula kochepa komanso kopepuka.
Ndi kuwongolera kwa kuzindikira ndi kachitidwe kazithunzi, ma laser rangefinder akutali omwe amatha kuyeza tilingo tating'ono ta 0.1m² kupitilira 20 km amafunikira. Chifukwa chake, ndikofunikira kuti muphunzire za laser rangefinder yapamwamba kwambiri.
M'zaka zaposachedwa, Lumispot Tech yachita khama pakufufuza, kupanga, kupanga ndi kugulitsa laser ya 1.57um wavelength yotetezedwa ndi maso yokhala ndi ngodya yaying'ono yobalalitsa ndi magwiridwe antchito apamwamba.
Posachedwa, Lumispot Tech, adapanga laser yotetezedwa ndi maso ya 1.57um yoziziritsa mpweya yokhala ndi mphamvu yapamwamba komanso mawonekedwe ophatikizika, chifukwa chakufunika kofunikira pakufufuza kwa miniization mtunda wautali wa laser rangefinder,. ziyembekezo ntchito, anali performanceace kwambiri, amphamvu kusinthasintha chilengedwe pansi pa osiyanasiyana kutentha ntchito kuchokera - 40 mpaka 65 digiri celsius,
Kupyolera mu equation yotsatirayi, ndi kuchuluka kwachulukidwe kwa maumboni ena, powongolera mphamvu yotulutsa pachimake ndikuchepetsa ngodya yobalalitsa mitengo, imatha kukonza mtunda woyezera wa rangefinder. Zotsatira zake, zinthu ziwirizi: mtengo wamphamvu yotulutsa nsonga ndi mtengo wawung'ono wobalalitsa ngodya yophatikizika ya laser yokhala ndi ntchito yoziziritsidwa ndi mpweya ndiye gawo lofunikira pakusankha luso la kuyeza mtunda kwa zofufuza zenizeni.
Gawo lofunikira pakuzindikira laser yokhala ndi mawonekedwe otetezedwa ndi maso ndi njira ya optical parametric oscillator (OPO), kuphatikiza kusankha kwa kristalo wopanda mzere, njira yofananira gawo ndi kapangidwe ka OPO interiol. Kusankhidwa kwa Krustalo Yopanda mzere kumadalira kokwanira kwakukulu kopanda mzere, kuwonongeka kwakukulu kwa ressiance, kukhazikika kwamankhwala ndi zinthu zakuthupi komanso njira zakukulira, etc., kufananitsa gawo kuyenera kukhala patsogolo. Sankhani njira yofananira ndi gawo losafunikira lomwe lili ndi ngodya yayikulu yovomerezeka ndi ngodya yaying'ono yonyamuka; Kapangidwe ka OPO kamene kamayenera kuganiziridwa bwino ndi mtengo wamtengowo pamaziko otsimikizira kudalirika.kusintha kokhota kwa KTP-OPO kutulutsa kwakutali ndi mbali yofananira ndi ngodya, pomwe θ=90 °, kuwala kwa siginecha kumatha kutulutsa diso lamunthu motetezeka. laser. Chifukwa chake, kristalo yopangidwa imadulidwa mbali imodzi, kufananiza kwa ngodya kumagwiritsidwa ntchito θ = 90 °, φ=0 °, ndiko kuti, kugwiritsa ntchito njira yofananira kalasi, pomwe kristalo yogwira ntchito yopanda malire ndiyo yayikulu kwambiri ndipo palibe zotsatira zobalalika. .
Kutengera kuganiziridwa mozama kwa nkhani yomwe ili pamwambapa, kuphatikizidwa ndi kukula kwa njira ndi zida zapakhomo zapanyumba, njira yolimbikitsira ukadaulo ndi: OPO itengera Gulu lachiwiri losagwirizana ndi gawo lofananira lakunja kwapawiri-cavity KTP-OPO. kupanga; ma 2 KTP-OPO amachitika moyima munjira ya tandem kuti apititse patsogolo kusinthika komanso kudalirika kwa laser monga zikuwonetsedwa muChithunzi 1Pamwamba.
Pump source ndikudzifufuza nokha ndikupanga makina a laser okhazikika a semiconductor, okhala ndi ntchito yozungulira 2% kwambiri, mphamvu yayikulu ya 100W pa bar imodzi ndi mphamvu yonse yogwira ntchito ya 12,000W. Prism yakumanja, galasi lowonetsera zonse ndi polarizer imapanga polarization yopindika yolumikizana ndi zotuluka, ndipo prism yakumanja ndi ma waveplate amazunguliridwa kuti apeze zomwe akufuna 1064 nm laser coupling. Njira ya Q modulation ndi kukakamizidwa kwa electro-optical Q modulation kutengera kristalo wa KDP.

Chithunzi 2: The arc-shape bar array module kudzera pakudzitukumula,
ndi ndodo ya kristalo ya YAG pakati.
TheChithunzi 2ndi mipiringidzo yooneka ngati arc, kuyika ndodo za kristalo za YAG ngati sing'anga ya laser mkati mwa module, ndikuyika kwa 1%. Pofuna kuthetsa kutsutsana pakati pa kayendetsedwe ka laser lateral ndi kugawa kofanana kwa laser output, kugawa kofanana kwa gulu la LD pamtunda wa madigiri 120 kunagwiritsidwa ntchito. Gwero la mpope ndi 1064nm wavelength, ma module awiri a 6000W opindika opindika pamndandanda wakupopa kwa semiconductor tandem. Mphamvu zotulutsa ndi 0-250mJ ndi kugunda m'lifupi pafupifupi 10ns ndi ma frequency olemera a 20Hz. patsekeke apangidwe ntchito, ndipo 1.57μm wavelength laser ndi linanena bungwe pambuyo tandem KTP nonlinear kristalo.
Chithunzi 3Chojambula chowoneka bwino cha 1.57um wavelength pulsed laser
Chithunzi 4: 1.57um wavelength pulsed laser chitsanzo zida
Chithunzi 5:Kutulutsa kwa 1.57μm
Chithunzi 6:Kusintha kwachangu kwa gwero la mpope
Kusintha mphamvu ya laser measuremnt kuti muyese mphamvu yotulutsa mitundu iwiri ya kutalika kwa mafunde motsatana. Malinga ndi chithunzi chomwe chili pansipa, kuyambiranso kwa mtengo wamagetsi kunali mtengo wapakati pa 20Hz ndi mphindi imodzi yogwira ntchito. Pakati pawo, mphamvu yopangidwa ndi 1.57um wavelenth laser imakhala ndi kusintha kosinthika ndi ubale wa 1064nm wavelength pump source energy. Pamene mphamvu ya gwero la mpope ikufanana ndi 220mJ, mphamvu yotulutsa mphamvu ya 1.57um wavelength laser imatha kukwaniritsa 80mJ, ndi kutembenuka kufika 35%. Popeza kuwala kwa siginecha ya OPO kumapangidwa pansi pa mphamvu yamphamvu yamphamvu yowunikira pafupipafupi, mtengo wake ndi wapamwamba kuposa mtengo wa 1064 nm woyambira pafupipafupi, ndipo mphamvu yake yotulutsa imakula mwachangu mphamvu yopopayo ikapitilira kuchuluka kwa OPO. . Ubale pakati pa mphamvu ya OPO yotulutsa mphamvu ndi mphamvu ndi mphamvu zowunikira pafupipafupi zikuwonetsedwa pachithunzichi, pomwe zitha kuwoneka kuti kutembenuka mtima kwa OPO kumatha kufika 35%.
Pomaliza, 1.57μm wavelength laser pulse linanena bungwe ndi mphamvu yaikulu kuposa 80mJ ndi laser kugunda m'lifupi 8.5ns chingapezeke. mbali yosiyana ya mtengo wa laser wotulutsa kudzera mu chowonjezera cha laser ndi 0.3mrad. kuyeza ndi kusanthula kukuwonetsa kuti kuthekera kwa kuyeza kwamitundu yosiyanasiyana ya pulsed laser rangefinder pogwiritsa ntchito laser iyi kumatha kupitilira 30km.
