Lumispot Technology Co., Ltd., raws li xyoo ntawm kev tshawb fawb thiab kev loj hlob, ua tiav ib qho me me thiab lub teeb yuag pulsed laser nrog lub zog ntawm 80mJ, repetition zaus ntawm 20 Hz thiab tib neeg lub qhov muag-kev nyab xeeb wavelength ntawm 1.57μm. Qhov kev tshawb fawb no tau ua tiav los ntawm kev nce kev sib tham ntawm KTP-OPO thiab optimizing cov zis ntawm lub twj tso kua mis qhov chaw diode laser module. Raws li cov txiaj ntsig kev xeem, lub laser no ua tau raws li qhov xav tau ntawm kev ua haujlwm kub ntawm -45 ℃ to 65 ℃ nrog kev ua tau zoo, mus txog qib siab hauv Suav teb.
Pulsed Laser Rangefinder yog qhov ntsuas qhov deb los ntawm qhov zoo ntawm laser mem tes taw qhia rau lub hom phiaj, nrog rau qhov zoo ntawm qhov muaj peev xwm nrhiav tau siab, muaj zog tiv thaiv kev cuam tshuam thiab cov qauv compact. Cov khoom siv dav siv hauv kev ntsuas engineering thiab lwm yam haujlwm. Qhov no pulsed laser rangefinding txoj kev yog feem ntau dav siv nyob rau hauv daim ntawv thov ntawm qhov ntev kev ntsuas. Nyob rau hauv qhov ntev-ntev rangefinder, nws yog qhov zoo dua los xaiv cov khoom siv lub xeev laser nrog lub zog siab thiab cov nqaj me me tawg lub kaum ntse ntse, siv Q-hloov tshuab los tso tawm cov nanosecond laser pulses.
Cov txheej txheem cuam tshuam ntawm pulsed laser rangefinder yog raws li hauv qab no:
(1) Tib neeg qhov muag-kev nyab xeeb Laser Rangefinder: 1.57um optical parametric oscillator yog maj mam hloov txoj hauj lwm ntawm cov tsoos 1.06um wavelength laser rangefinder nyob rau hauv feem ntau ntawm cov rangefinding teb.
(2) Miniaturized Tej thaj chaw deb Laser Rangefinder nrog me me thiab lub teeb-yuag.
Nrog rau kev txhim kho kev tshawb nrhiav thiab kev ua haujlwm ntawm cov duab, cov chaw taws teeb laser rangefinders muaj peev xwm ntsuas cov hom phiaj me me ntawm 0.1m² tshaj 20 km yuav tsum. Yog li ntawd, nws yog ib qho tseem ceeb kom kawm txog qhov ua tau zoo laser rangefinder.
Nyob rau hauv xyoo tas los no, Lumispot Tech tau siv zog rau kev tshawb fawb, tsim, tsim thiab muag ntawm 1.57um wavelength qhov muag-kev nyab xeeb lub xeev laser nrog me me beam tawg lub kaum ntse ntse thiab kev ua haujlwm siab.
Tsis ntev los no, Lumispot Tech, tsim ib qho 1.57um qhov muag-kev nyab xeeb wavelength cua txias laser nrog siab ncov lub zog thiab compact qauv, uas tshwm sim los ntawm cov tswv yim xav tau nyob rau hauv kev tshawb fawb ntawm minization ntev-ntev laser rangefinder,. Daim ntawv thov kev cia siab, muaj kev ua tau zoo heev, muaj zog ib puag ncig adaptability nyob rau hauv qhov dav ntawm kev ua haujlwm kub ntawm - 40 txog 65 degree celsius,
Los ntawm kev sib npaug hauv qab no, nrog rau qhov ruaj khov ntawm lwm yam kev siv, los ntawm kev txhim kho lub siab tshaj plaws tso zis zog thiab txo cov nqaj tawg lub kaum sab xis, nws tuaj yeem txhim kho qhov ntsuas qhov deb ntawm qhov rangefinder. Raws li qhov tshwm sim, 2 yam tseem ceeb: tus nqi ntawm lub siab tshaj plaws tso zis hluav taws xob thiab cov nqaj me me tawg lub kaum sab xis compact qauv laser nrog cua txias ua haujlwm yog qhov tseem ceeb ntawm kev txiav txim siab qhov kev ntsuas qhov deb ntawm qhov tshwj xeeb rangefinder.
Qhov tseem ceeb kom paub txog lub laser nrog tib neeg lub qhov muag-kev nyab xeeb wavelength yog optical parametric oscillator (OPO) txheej txheem, nrog rau kev xaiv ntawm non-linear siv lead ua, theem sib piv txoj kev thiab OPO interiol qauv tsim. Qhov kev xaiv ntawm Non-linear siv lead ua nyob ntawm qhov loj uas tsis yog-linear coefficient, kev puas tsuaj siab rau qhov pib, cov tshuaj lom neeg ruaj khov thiab lub cev muaj zog thiab cov txheej txheem kev loj hlob thiab lwm yam., theem sib txuam yuav tsum ua ntej. Xaiv cov theem tsis tseem ceeb sib piv nrog lub kaum sab xis txais loj thiab lub kaum sab xis me me; OPO kab noj hniav qauv yuav tsum coj mus rau hauv tus account efficiency thiab beam zoo nyob rau hauv lub hauv paus ntawm kev ntseeg tau. qhov hloov nkhaus ntawm KTP-OPO tso zis wavelength nrog theem sib piv lub kaum sab xis, thaum lub θ = 90 °, lub teeb liab teeb yuav raws nraim outputs tib neeg lub qhov muag zoo. laser. Yog li ntawd, tus tsim siv lead ua yog txiav nrog ib sab, lub kaum sab xis siv θ = 90 °, φ = 0 °, uas yog, kev siv cov chav kawm sib piv txoj kev, thaum siv lead ua zoo nonlinear coefficient yog qhov loj tshaj plaws thiab tsis muaj kev cuam tshuam. .
Raws li kev txiav txim siab zoo ntawm qhov teeb meem saum toj no, ua ke nrog kev txhim kho qib ntawm cov txheej txheem laser hauv tsev tam sim no thiab cov cuab yeej siv, qhov kev daws teeb meem zoo tshaj plaws yog: OPO txais yuav Class II tsis tseem ceeb theem-txhim kho sab nraud kab noj hniav dual-kab noj KTP-OPO tsim; 2 KTP-OPOs yog vertically xwm txheej nyob rau hauv ib tug tandem qauv los txhim kho conversion efficiency thiab laser kev ntseeg tau raws li qhia nyob rau hauvDaim duab 1Saum toj no.
Lub twj tso kua mis yog qhov kev tshawb nrhiav tus kheej thiab tsim cov khoom siv hluav taws xob txias semiconductor laser array, nrog rau lub voj voog ntawm 2% ntawm feem ntau, 100W lub zog siab tshaj plaws rau ib qho bar thiab tag nrho ua haujlwm lub zog ntawm 12,000W. Lub kaum sab xis prism, cov phiaj xwm txhua daim iav thiab cov polarizer tsim cov folded polarization ua ke tso zis resonant kab noj hniav, thiab lub kaum sab xis prism thiab waveplate yog tig kom tau qhov xav tau 1064 nm laser coupling tso zis.
