Lumispot Technology Co., Ltd., yakavakirwa pamakore ekutsvagisa nekusimudzira, yakabudirira kugadzira diki uye huremu huremu pulsed laser ine simba re80mJ, kudzokorora frequency ye20 Hz uye yemunhu-yakachengeteka yewavelength ye1.57μm. Mhedzisiro iyi yekutsvagisa yakawanikwa nekuwedzera kugona kutaura kweKTP-OPO uye nekugadzirisa kubuda kwepombi sosi diode laser module. Zvinoenderana nemhedzisiro yebvunzo, iyi laser inosangana neyakakura yekushanda tembiricha inodiwa kubva -45 ℃ kusvika 65 ℃ nekuita kwakanaka, kusvika padanho repamusoro muChina.
Pulsed Laser Rangefinder iri chinhambwe chekuyera chiridzwa nemukana welaser pulse yakanangidzirwa kune chinangwa, iine mafaniro eiyo yakakwirira-chaiyo yekutsvagira kugona, yakasimba anti-kupindira kugona uye compact chimiro. Chigadzirwa chacho chinoshandiswa zvakanyanya mukuyera kweinjiniya uye mamwe minda. Iyi pulsed laser rangefinding nzira inonyanya kushandiswa mukushandiswa kwekuyera kureba. Mune ino kureba-rengefinder, zviri nani kusarudza solid-state laser ine simba rakawanda uye diki danda rekuparadzira angle, uchishandisa iyo Q-switching tekinoroji kuburitsa iyo nanosecond laser pulses.
Iwo akakodzera maitiro e pulsed laser rangefinder ndeaya anotevera:
(1) Yemunhu Ziso-yakachengeteka Laser Rangefinder:1.57um optical parametric oscillator zvishoma nezvishoma iri kutsiva chinzvimbo cheyakajairwa 1.06um wavelength laser rangefinder mune yakawanda yenzvimbo dzekuwana.
(2) Miniaturized Remote Laser Rangefinder ine diki-saizi uye chiedza-uremu.
Nekuvandudzwa kwekuona uye kufungidzira system performance, kure kure laser rangefinders inokwanisa kuyera zvinangwa zvidiki zve 0.1m² pamusoro pe20 km inodiwa. Naizvozvo, zvinokasira kudzidza iyo yepamusoro-inoshanda laser rangefinder.
Mumakore achangopfuura, Lumispot Tech yakaisa simba mukutsvagisa, dhizaini, kugadzirwa uye kutengeswa kweiyo 1.57um wavelength ziso-yakachengeteka solid state laser ine diki danda rekuparadzira kona uye kushanda kwakanyanya kwekushanda.
Nguva pfupi yadarika, Lumispot Tech, yakagadzira 1.57um ziso-yakachengeteka wavelength mhepo yakatonhodzwa laser ine yakakwirira yepamusoro simba uye compact chimiro, zvichibva mukudiwa kunoshanda mukati mekutsvagisa kweminization kure-kure laser rangefinder,.Mushure mekuyedza, iyi laser inoratidza yakafara. tarisiro yekushandisa, yaive neyakanakisa performanceace, yakasimba nharaunda inochinjika pasi pehupamhi hwekushanda tembiricha kubva -40 kusvika 65 degree celsius,
Kuburikidza neinotevera equation, nehuwandu hwakatarwa hweimwe referensi, nekuvandudza peak yekubuda simba uye kudzikisa danda rekuparadzira angle, inogona kuvandudza chinhambwe chekuyera cheiyo rangefinder. Nekuda kweizvozvo, izvo zviviri zvinhu: kukosha kwepeak yekubuda simba uye diki danda rekuparadzira kona compact chimiro laser ine mweya-yakatonhodzwa basa ndicho chikamu chakakosha chiri kusarudza kureba kuyerwa kugona kweiyo chaiyo rangefinder.
Chikamu chakakosha chekuziva iyo laser ine yeziso-yakachengeteka wavelength ndeye optical parametric oscillator (OPO) dhizaini, kusanganisira sarudzo yeisiri-mutsara crystal, chikamu chekufananidza nzira uye OPO interiol chimiro dhizaini. Sarudzo yeIsiri-mutsara crystal inotsamira pane hombe isiri-mutsara coefficient, yakakwirira kukuvara ressiance chikumbaridzo, yakagadzikana makemikari uye emuviri zvimiro uye hunyanzvi hwekukura nezvimwewo, kuenzanisa kwechikamu kunofanira kutora pamberi. Sarudza iyo isiri-yakakosha chikamu chekufananidza nzira ine hombe yekugamuchira angle uye diki yekusimuka kona; Iyo OPO mhango chimiro inofanirwa kutarisisa kugona uye danda remhando pahwaro hwekuona kuvimbika. shanduko yeKTP-OPO inobuda wavelength ine chikamu chekufananidza angle, kana iyo θ = 90 °, mwenje wechiratidzo unogona kunyatsoburitsa ziso remunhu rakachengeteka. laser. Nokudaro, kristaro yakagadzirwa inochekwa pamwe chete nerutivi rumwe, iyo angle inofananidzwa inoshandiswa θ = 90 °, φ=0 °, kureva, kushandiswa kwekirasi yekufananidza nzira, apo kristaro inoshanda isina mutsara coefficient ndiyo yakakura uye hapana kupararira. .
Zvichienderana nekutarisisa kwakadzama kwenyaya iri pamusoro, yakasanganiswa nedanho rekusimudzira yeazvino laser tekinoroji uye zvishandiso, iyo optimization tekinoroji mhinduro ndeiyi: Iyo OPO inotora Kirasi II isiri-yakakosha chikamu-inofananidzira yekunze mhango dual-cavity KTP-OPO. design; iyo 2 KTP-OPOs inoitika yakatwasuka mune tandem chimiro chekuvandudza shanduko inoshanda uye kuvimbika kwelaser sezvakaratidzwa mu.Mufananidzo 1Pamusoro.
Pombi sosi ndiyo yekuzvitsvagisa uye yakagadziridzwa conductive yakatonhorera semiconductor laser array, ine basa kutenderera kwe2% zvakanyanya, 100W peak simba rebhari imwechete uye yakazara kushanda simba re12,000W. Iyo yekurudyi-ekona prism, planar yese-ino ratidza girazi uye polarizer inoumba yakapetwa polarization yakasanganiswa inobuda resonant cavity, uye yekurudyi-ekona prism uye waveplate inotenderedzwa kuti iwane inodiwa 1064 nm laser coupling inobuda. Iyo Q modulation nzira ndeye yakamanikidzwa inoshanda electro-optical Q modulation yakavakirwa paKDP crystal.

Mufananidzo 2: Iyo arc-shaped bar array module kuburikidza nekuzvisimudzira,
ine YAG crystal tsvimbo pakati.
TheMufananidzo 2ndiyo arc-shaped bar stacks, kuisa iyo YAG crystal tsvimbo seye laser medium mukati memodule, ine kusungirirwa kwe1%. Kugadzirisa kupokana pakati pe lateral laser movement uye symmetric kugovera kwe laser kubuda, symmetric kugovera kweLD array pakona ye120 degrees yakashandiswa. Iyo pombi sosi ndeye 1064nm wavelength, maviri 6000W curved array bar modules mune akatevedzana semiconductor tandem kupomba. Simba rinobuda 0-250mJ ine pulse upamhi hunosvika gumi uye inorema frequency ye20Hz. mhango yakapetwa inoshandiswa, uye iyo 1.57μm wavelength laser inobuda mushure metandem KTP nonlinear crystal.
Girafu 3Iyo dimensional dhizaini ye1.57um wavelength pulsed laser
Girafu 4:1.57um wavelength pulsed laser sampuli michina
Girafu 5:1.57μm kubuda
Girafu 6:Iko kutendeuka kushanda zvakanaka kwepombi sosi
Kugadzirisa iyo laser simba measuremnt kuyera simba rekubuda remhando mbiri dzewavelength zvichiteerana. Zvinoenderana negirafu inoratidzwa pazasi, kudzoserwa kwesimba kukosha kwaive kukosha kweavhareji kushanda pasi pe20Hz ine 1 min yekushanda nguva. Pakati pavo, iyo simba inogadzirwa ne1.57um wavelenth laser ine shanduko inotenderera nehukama hwe1064nm wavelength pombi sosi simba. Kana simba repombi sosi rakaenzana ne 220mJ, simba rekubuda kweye 1.57um wavelength laser rinokwanisa kuwana 80mJ, nehuwandu hwekushandura hunosvika 35%. Sezvo iyo OPO chiratidzo chemwenje ichigadzirwa pasi pekuita kweimwe simba density yeyakakosha frequency mwenje, kukosha kwayo kwechikumbaridzo kwakakwira kupfuura kukosha kwechikumbaridzo che1064 nm fundamental frequency light, uye simba rayo rekubuda rinowedzera nekukurumidza mushure mekunge simba rekupomba rapfuura kukosha kweOPO. . Hukama huri pakati peOPO inobuda simba uye kushanda nesimba neiyo yakakosha frequency light output energy inoratidzwa mumufananidzo, kubva paunogona kuonekwa kuti kutendeuka kweOPO kunogona kusvika ku35%.
Pakupedzisira, 1.57μm wavelength laser pulse kubuda nesimba rakakura kupfuura 80mJ uye laser pulse wide ye8.5ns inogona kuwanikwa. iyo divergence angle yekubuda kwelaser beam kuburikidza nelaser beam expander ndeye 0.3mrad. simulations uye ongororo inoratidza kuti chiyero chekuyera kugona kweiyo pulsed laser rangefinder uchishandisa iyi laser inogona kudarika 30km.
