Lumispot Technology Co., Ltd., zvichibva mumakore ekutsvaga nekugadzira, yakabudirira kugadzira laser diki uye ine huremu hwakareruka ine simba re80mJ, kudzokorora kwe20 Hz uye wavelength isingakuvadzi maziso emunhu ye1.57μm. Mhedzisiro iyi yekutsvagisa yakawanikwa nekuwedzera kushanda zvakanaka kweKTP-OPO uye kugadzirisa kubuda kwepombi source diode laser module. Zvichienderana nemhedzisiro yekuyedza, laser iyi inosangana nezvinodiwa pakushanda tembiricha kubva -45 ℃ kusvika 65 ℃ nekushanda kwakanaka, kusvika padanho repamusoro muChina.
Pulsed Laser Rangefinder chishandiso chekuyera daro nekuda kwe laser pulse yakanangana nechinangwa, ine kunaka kwekugona kuwana rangefinding nemazvo, kugona kwakasimba kwekudzivirira kupindira uye chimiro chakamanikana. Chigadzirwa ichi chinoshandiswa zvakanyanya mukuyera mainjiniya nedzimwe nzvimbo. Iyi nzira ye pulsed laser rangefinding inonyanya kushandiswa mukushandisa kuyera daro refu. Mune iyi long distance rangefinder, zviri nani kusarudza solid-state laser ine simba rakawanda uye small beam scatter angle, uchishandisa tekinoroji yeQ-switching kuti ibudise nanosecond laser pulses.
Mafambiro akakodzera e pulsed laser rangefinder ndeaya anotevera:
(1) Chishandiso cheLaser Rangefinder cheHuman Eye-safe: 1.57um optical parametric oscillator chiri kutsiva zvishoma nezvishoma nzvimbo yechinyakare che1.06um wavelength laser rangefinder munzvimbo zhinji dzekutsvaga ruzivo.
(2) Miniaturized Remote Laser Rangefinder ine saizi diki uye yakareruka.
Nekuvandudzika kwekushanda kwesystem yekuona nekutora mifananidzo, zvinodiwa ma "laser rangefinder" ari kure anokwanisa kuyera zvinangwa zvidiki zve 0.1m² kupfuura makiromita makumi maviri. Saka, zvakakosha kuti tidzidze "laser rangefinder" inoshanda zvakanyanya.
Mumakore achangopfuura, Lumispot Tech yakaedza kutsvaga, kugadzira, kugadzira, uye kutengesa laser yakasimba ye1.57um wavelength ine angle diki yekupararira kwemwaranzi uye mashandiro akakwirira.
Munguva pfupi yapfuura, Lumispot Tech yakagadzira laser inotonhorera yemhepo ye1.57um isingakuvadzi maziso ine simba repamusoro uye chimiro chakabatana, zvichibva pakudiwa kwekushandisa mukutsvaga kwe "long-distance laser rangefinder". Mushure mekuyedza, laser iyi inoratidza mikana yakawanda yekushandisa, ine mashandiro akanaka, inochinjika zvakanyanya nharaunda pasi pemhando dzakasiyana dzekushisa kubva -40 kusvika 65 degrees celsius,
Kuburikidza ne equation inotevera, nehuwandu hwakatarwa hwezvimwe zvinorehwa, nekuvandudza simba rekubuda kwepamusoro uye kuderedza kona yekupararira kwedanda, zvinogona kuvandudza daro rekuyera re rangefinder. Nekuda kweizvozvo, zvinhu zviviri: kukosha kwesimba rekubuda kwepamusoro uye kona yekupararira kwedanda diki, laser ine basa rakatonhodzwa nemhepo, ndiyo chikamu chakakosha chinosarudza kugona kwekuyera daro kwerangefinder chaiyo.
Chikamu chakakosha chekushandisa laser ine wavelength yakachengeteka maziso evanhu inzira ye optical parametric oscillator (OPO), kusanganisira sarudzo ye non-linear crystal, phase matching method uye OPO interiol structure design. Sarudzo ye Non-linear crystal inoenderana ne big non-linear coefficient, high damage resiance threshold, stable chemical and physical properties uye mature growth techniques etc., phase matching inofanira kutanga. Sarudza nzira ye non-critical phase matching ine large acceptance angle uye small departure angle; OPO cavity structure inofanira kufunga nezvekushanda zvakanaka uye beam quality zvichibva pakuona kuvimbika. Change curve ye KTP-OPO output wavelength ine phase matching angle, kana θ=90°, signal light inogona kuburitsa laser yakachengeteka maziso evanhu. Saka, crystal yakagadzirwa inochekwa parutivi rumwe, angle matching inoshandisa θ=90°，φ=0°, kureva kuti, kushandisa class matching method, apo crystal effective nonlinear coefficient ndiyo yakakura uye hapana dispersion effect.
Zvichibva pakuongororwa kwakazara kwenyaya iri pamusoro apa, pamwe chete nedanho rekuvandudzwa kwehunyanzvi hwemazuva ano hwe laser nemidziyo, mhinduro yehunyanzvi yekuvandudza ndeye: OPO inoshandisa dhizaini yeClass II non-critical phase-matching external cavity dual-cavity KTP-OPO; ma KTP-OPO maviri akagadzirwa ne vertical in a tandem structure kuti avandudze kushanda kwekushandura uye kuvimbika kwe laser sezvakaratidzwa muMufananidzo 1Pamusoro.
Pombi inobva papombi ndiyo inodzitsvagurudza yoga uye yakagadzirwa ne conductive cooled semiconductor laser array, ine duty cycle ye2%, simba guru re100W re single bar uye simba rose rekushanda re12,000W. Prism ye right-angle, planar all-reflective mirror uye polarizer zvinoumba folded polarization coupled output resonant cavity, uye right-angle prism ne waveplate zvinotenderedzwa kuti zviwane 1064 nm laser coupling output inodiwa. Nzira ye Q modulation i pressurized active electro-optical Q modulation yakavakirwa paKDP crystal.

Mufananidzo 2: Module yebar array yakaita searc shaped via self-development,
netsvimbo yekristaro yeYAG pakati.
IyoMufananidzo 2ndiyo mitsetse yemabhawa yakaita searc, ichiisa YAG crystal rods se laser medium mukati memodule, ine huwandu hwe1%. Kugadzirisa kusawirirana kuripo pakati pekufamba kwelaser lateral uye symmetric distribution ye laser output, kwakashandiswa symmetric distribution yeLD array pakona ye120 degrees. Pombi inobva 1064nm wavelength, maviri 6000W curved array bar modules mu series semiconductor tandem pumping. Simba rekubuda i0-250mJ ine pulse width yeinenge 10ns uye heavy frequency ye20Hz. panoshandiswa folded cavity, uye 1.57μm wavelength laser inobuda mushure me tandem KTP nonlinear crystal.

Kugadzirisa chiyero chesimba relaser kuti chiyere simba rekubuda kwemhando mbiri dzewavelength zvakateerana. Zvichienderana negirafu inoratidzwa pazasi, simba rekudzoka kwesimba raive avhareji yekushanda pasi pe20Hz nenguva yekushanda yeminiti imwe. Pakati pazvo, simba rinogadzirwa ne1.57um wavelenth laser rine shanduko inotevera nehukama hwesimba repampu yewavelength ye1064nm. Kana simba repampu rakaenzana ne220mJ, simba rekubuda re1.57um wavelength laser rinokwanisa kusvika 80mJ, nechiyero chekushandura kusvika 35%. Sezvo chiedza cheOPO chinogadzirwa pasi pesimba rehumwe huremu hwechiedza chefrequency, kukosha kwaro kwemuganho kwakakwira kupfuura kukosha kwemuganho we1064 nm fundamental frequency light, uye simba rayo rekubuda rinowedzera nekukurumidza mushure mekunge simba rekupomba rapfuura kukosha kwemuganho weOPO. Hukama huripo pakati pesimba reOPO rinobuda uye kushanda zvakanaka nesimba re frequency light rinobuda zvakanaka hunoratidzwa mumufananidzo, umo zvinogona kuonekwa kuti kushanda zvakanaka kweOPO kunogona kusvika 35%.
Pakupedzisira, kugona kuburitsa pulse yelaser ye1.57μm wavelength ine simba rinodarika 80mJ uye upamhi hwelaser yepulse ye8.5ns kunogona kuwanikwa. Kona yekusiyana kwedanda relaser rinobuda kuburikidza nelaser beam expander i0.3mrad. Kuenzanisa nekuongorora zvinoratidza kuti kugona kuyera range kwepulsed laser rangefinder inoshandisa laser iyi kunogona kudarika 30km.
