Lumispot Technology Co., Ltd., ishingiye ku myaka y'ubushakashatsi n'iterambere, yateje imbere ubunini buto n'uburemere bworoshye pulsed laser ifite ingufu za 80mJ, inshuro zisubiramo za 20 Hz hamwe n'uburebure bw'amaso ya muntu bingana na 1.57 mm. Ibisubizo byubushakashatsi byagezweho mu kongera imikorere yikiganiro cya KTP-OPO no guhitamo umusaruro wa pompe ya diode laser module. Ukurikije ibisubizo byikizamini, iyi laser yujuje ubushyuhe bwakazi bukenewe kuva -45 ℃ kugeza 65 ℃ hamwe nibikorwa byiza, bigera kurwego rwo hejuru mubushinwa.
Gusunika Laser Rangefinder nigikoresho cyo gupima intera ukoresheje inyungu ya laser pulse yerekejwe ku ntego, hamwe nubushobozi bwubushobozi buhanitse bwo kugereranya, imbaraga zo kurwanya-kwivanga hamwe nuburyo bworoshye. Ibicuruzwa bikoreshwa cyane mubipimo byubuhanga nizindi nzego. Ubu buryo bwa pulsed laser rangefinding uburyo bukoreshwa cyane mugukoresha intera ndende. Muri ubu burebure burebure, nibyiza cyane guhitamo lazeri ikomeye-ifite ingufu nyinshi hamwe ninguni ntoya ikwirakwiza inguni, ukoresheje tekinoroji ya Q-ihindura kugirango isohore nanosekond laser pulses.
Inzira zifatika za pulsed laser rangefinder nizi zikurikira:
.
(2) Miniaturized Remote Laser Rangefinder ifite ubunini-buke n'uburemere.
Hamwe nogutezimbere imikorere ya sisitemu yo kwerekana no kwerekana amashusho, hasabwa kure ya laser rangefinders ishoboye gupima intego ntoya ya 0.1m² hejuru ya kilometero 20. Kubwibyo, birihutirwa kwiga cyane-laser laserfinder.
Mu myaka yashize, Lumispot Tech yashyize ingufu mubushakashatsi, gushushanya, gukora no kugurisha 1.57um yumurambararo wamaso yumutekano wa lazeri ikomeye kandi ifite urumuri ruto rukwirakwiza kandi rukora cyane.
Vuba aha, Lumispot Tech, yateguye 1.57um yumutekano wumuyaga wogukonjesha ikirere gikonjesha lazeri ifite imbaraga zo hejuru cyane hamwe nuburyo bworoshye, biva mubisabwa bifatika mubushakashatsi bwo kugabanya minisiteri ndende ya lazeri, .Nyuma yubushakashatsi, iyi laser yerekana ubugari ibyifuzo byo gusaba, bifite imikorere myiza, ihindagurika ryibidukikije munsi yubushyuhe bwakazi kuva kuri dogere 40 kugeza kuri 65,
Binyuze mu kugereranya gukurikira, hamwe nubunini buhamye bwibindi bikoresho, mugutezimbere imbaraga zisohoka no kugabanya inguni ikwirakwiza, irashobora kunoza intera yo gupima intera. Nkigisubizo, ibintu 2: agaciro kimbaraga zisohoka nimbaraga ntoya ikwirakwiza inguni igizwe na laser hamwe numurimo ukonjesha ikirere nigice cyingenzi kigena ubushobozi bwo gupima intera ya interineti yihariye.
Igice cyingenzi kugirango tumenye lazeri hamwe nuburebure bwumuntu wumuntu ni tekinike ya optique parametric oscillator (OPO), harimo guhitamo uburyo butari umurongo wa kirisiti, uburyo bwo guhuza ibyiciro hamwe nuburyo bwa OPO interiol. Guhitamo kutari umurongo wa kirisiti biterwa na coefficient nini itari umurongo, kwangirika kwinshi kwinshi, imiti ihamye ya chimique na physique hamwe nubuhanga bukuze bukuze nibindi, guhuza icyiciro bigomba gufata umwanya wambere. Hitamo uburyo budahwitse bwo guhuza uburyo bunini bwo kwemererwa no gutambuka gato; Imiterere ya cavit ya OPO igomba kuzirikana imikorere nubuziranenge bwibiti hashingiwe ku kwemeza kwizerwa.impinduka yo guhinduranya ya KTP-OPO isohoka yumurambararo hamwe na fonction angana, iyo θ = 90 °, urumuri rwibimenyetso rushobora gusohora neza ijisho ryumuntu neza laser. Kubwibyo, igishushanyo mbonera cya kirisiti cyaciwe kuruhande rumwe, inguni ihuye yakoreshejwe θ = 90 ° ，φ = 0 °, ni ukuvuga, gukoresha uburyo bwo guhuza ibyiciro, mugihe kristu ikora neza idafite umurongo nini nini kandi nta ngaruka zo gutatanya .
Hashingiwe ku gusuzuma mu buryo bunonosoye ikibazo cyavuzwe haruguru, uhujwe n’urwego rwiterambere rw’ubuhanga n’ibikoresho bya lazeri bigezweho, igisubizo cya tekiniki yo gutezimbere ni: OPO ifata icyiciro cya kabiri kitari icyiciro cya mbere gihuza icyuho cyo hanze cyitwa cavity KTP-OPO igishushanyo; 2 KTP-OPO ni vertike yibintu muburyo bwa tandem kugirango tunoze imikorere yo guhindura no kwizerwa kwa laser nkuko bigaragara muriIgishushanyo 1Hejuru.
Inkomoko ya pompe nubushakashatsi bwonyine kandi bwateje imbere imiyoboro ikonjesha ya semiconductor laser array, hamwe ninshingano yumusoro wa 2% byibuze, 100W power power kumurongo umwe nimbaraga zose zakazi zingana na 12,000W. Prism-iburyo-prism, planar byose-byerekana indorerwamo hamwe na polarizer ikora polarisiyose ikomatanyirijwe hamwe isohora resonant cavity, kandi prism-iburyo ya prism hamwe na flamplate irazunguruka kugirango ibone ibyifuzwa 1064 nm bya laser. Uburyo bwa Q modulation nuburyo bukoreshwa na electro-optique Q modulisiyo ishingiye kuri kristu ya KDP.

Igishushanyo 2: Arc-shusho yumurongo wumurongo module ukoresheje kwiteza imbere,
hamwe na YAG inkoni ya kirisiti hagati.
UwitekaIgishushanyo 2ni arc-imeze nkibibari, shyira inkoni ya YAG ya kristu nkibikoresho bya laser imbere muri module, hamwe na concentration ya 1%. Kugira ngo hakemurwe kwivuguruza hagati yimikorere ya lazeri no gukwirakwiza kugabana ibyasohotse, hakoreshejwe uburyo bwo gukwirakwiza LD umurongo ku mpande za dogere 120. Inkomoko ya pompe ni 1064nm yumurambararo, bibiri 6000W bigoramye umurongo wa bar bar module muburyo bwa semiconductor tandem pomping. Ingufu zisohoka ni 0-250mJ hamwe na pulse ubugari bwa 10ns hamwe numurongo uremereye wa 20Hz. umwobo wikubye ukoreshwa, hamwe na 1.57 mm ya lazeri ya laser isohoka nyuma ya tandem KTP idafite umurongo.
Igishushanyo cya 3Igishushanyo mbonera cya 1.57um yumurambararo wa pulsed laser
Igishushanyo cya 4: 1.57um yumurambararo wa pulsed laser sample ibikoresho
Igishushanyo 5:Ibisohoka 1.57 mm
Igishushanyo cya 6:Guhindura imikorere ya pompe
Guhuza ingufu za laser zipima gupima imbaraga zisohoka zubwoko 2 bwuburebure. Ukurikije igishushanyo cyerekanwe hepfo, gusubiramo agaciro k'ingufu byari impuzandengo yagaciro ikora munsi ya 20Hz hamwe na 1 min yo gukora. Muri byo, ingufu zitangwa na 1.57um ya wavelenth laser ifite impinduka zihuye nubusabane bwingufu za pompe 1064nm. Iyo ingufu ziva mumashanyarazi zihwanye na 220mJ, ingufu zisohoka ya 1.57um yumurambararo wa laser irashobora kugera kuri 80mJ, hamwe nigipimo cyo guhindura kigera kuri 35%. Kubera ko urumuri rw'ibimenyetso rwa OPO rutangwa hifashishijwe ibikorwa byubucucike bwurumuri rwibanze rwibanze, agaciro kayo karenze hejuru yumubare ntarengwa wa 1064 nm yumucyo wibanze, kandi ingufu zisohoka ziyongera vuba nyuma yingufu zo kuvoma zirenze agaciro ka OPO . Isano iri hagati yingufu za OPO zisohoka ningufu hamwe ningufu zingenzi zitanga ingufu zumucyo zerekanwa mubishushanyo, aho bigaragara ko imikorere yo guhindura OPO ishobora kugera kuri 35%.
Ubwanyuma, 1.57μm yumurambararo wa laser pulse isohoka ifite ingufu zirenga 80mJ hamwe nubugari bwa laser ya 8.5ns irashobora kugerwaho. impande zinyuranye zisohoka laser yamashanyarazi binyuze muri laser beam yagura ni 0.3mrad. kwigana no gusesengura byerekana ko ubushobozi bwo gupima intera ya pulsed laser rangefinder ukoresheje iyi laser irashobora kurenga 30km.
