Dab tsi yog Daim Ntawv Thov Ntawm Visible Wavelength Lasers?

As one of the shortest visible wavelengths, 405 nm violet lasers stand out for their high energy density and excellent optical resolution, thanks to their short wavelength that enables focusing into extremely small spot sizes. Qhov no ua rau lawv thawj qhov kev xaiv rau siab -precision industrial detection thiab microfabrication scenarios.

Hauv kev tsim khoom semiconductor, 405 nm kab lasers tau dav siv los kuaj xyuas micro- qhov tsis xws luag ntawm wafer nto, kom ntseeg tau qhov zoo ntawm semiconductor chips thiab txhim kho cov khoom tsim tawm. Lawv kuj tau siv rau hauv 3D contour ntsuas ntawm precision Cheebtsam, xws li cov khoom siv tsheb thiab cov khoom siv hluav taws xob, muab cov ntaub ntawv loj loj rau cov kab ntau lawm.

Tshaj li kev tshawb nrhiav kev lag luam, 405 nm violet lasers tau siv ntau dua hauv kev kho mob, xws li dermatology thiab ophthalmology, rau lawv lub peev xwm los tsom rau cov ntaub so ntswg tshwj xeeb nrog kev puas tsuaj tsawg heev. Hauv kev lag luam thoob ntiaj teb kev lag luam, 405 nm laser modules yog nyob rau hauv kev thov siab ntawm cov tuam txhab semiconductor, precision ntsuas cov khoom lag luam, thiab cov tuam txhab kho mob.

450 nm xiav lasers tau txais kev nrov nrov vim lawv qhov siab nqus los ntawm hemoglobin thiab cov nyhuv thermal diffusion tsawg, ua rau lawv muaj ntau yam cuab yeej thoob plaws ntau qhov chaw. Hauv kev kho mob, lawv tau hloov kho qhov kev phais mob tsawg kawg nkaus - siv hauv kev kho hniav mos, cov txheej txheem otolaryngology, thiab kho pob txuv.

Piv txwv li, hauv kev phais hniav, 450 nm xiav lasers pab txiav cov pos hniav kom meej nrog cov ntshav tsawg thiab kho sai dua, txhim kho cov neeg mob kev paub zoo. Hauv dermatology, lawv tua pob txuv tau zoo- ua rau cov kab mob, muab cov tshuaj uas tsis yog -invasive rau inflammatory pob txuv.
Hauv cov ntawv thov kev lag luam, 450 nm xiav lasers yog siv rau siab - kev kos cim thiab kos rau ntawm cov ntaub ntawv xws li iav, ceramics, thiab plastics, xa cov qauv ntshiab, zoo yam tsis muaj kev puas tsuaj rau lub substrate. Tsis tas li ntawd, nrog rau kev txhim kho kev tiv thaiv thiab thev naus laus zis thev naus laus zis, 450 nm pom GaN DFB lasers tau raug tsim los rau dual - siv aerospace applications. Rau cov neeg lag luam thoob ntiaj teb, 450 nm laser cov khoom muaj peev xwm ua lag luam, tshwj xeeb tshaj yog nyob rau hauv cov cuab yeej kho mob thiab kev tiv thaiv thev naus laus zis.

532 nm ntsuab lasers, tsim los ntawm ntau zaus ob npaug rau thev naus laus zis raws li Nd:YAG crystals, paub txog lawv cov kab teeb pom kev zoo, kev ua haujlwm ruaj khov, thiab muaj zog tiv thaiv - muaj peev xwm cuam tshuam. Lawv tau siv dav hauv kev ua lag luam precision, xws li PCB kos npe, iav txiav, thiab micro-nano machining, kom ntseeg tau tias cov khoom siv tau zoo thiab cov khoom siv hluav taws xob tsawg tsawg. Hauv kev kho mob, 532 nm lasers yog siv nyob rau hauv ophthalmic surgeries, thiab pigmented daim tawv nqaij kev kho mob kab mob, nrog rau kev tshem tawm tattoo, vim lawv siab nqus los ntawm melanin thiab meej cov ntaub so ntswg.

Tshaj li cov ntawv thov kev lag luam thiab kev kho mob, 532 nm ntsuab lasers ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb tshawb fawb, xws li laser-induced fluorescence (LIF), particle duab velocimetry (PIV), thiab laser ultrasound, muab cov teeb pom kev zoo rau kev tshawb fawb.

Lawv kuj tau siv rau hauv cov khoom siv - xeev lidar systems, pab txhawb kev txhim kho kev tsav tsheb tsis muaj zog thiab kev soj ntsuam ib puag ncig. Hauv kev lag luam thoob ntiaj teb, 532 nm nanosecond thiab picosecond lasers tau tshawb nrhiav los ntawm cov tuam txhab tsim khoom, cov chaw tshawb fawb, thiab cov chaw kho mob.

Liab lasers nrog wavelengths ntawm 635 nm thiab 650 nm yog cov feem ntau pom lasers, paub txog lawv cov nqi qis, paub tab technology, thiab dav siv. Hauv kev tsim khoom, lawv tau siv dav rau qhov chaw, kev sib dhos, thiab qib hauv cov khoom siv laser, xws li laser npav tshuab, vuam tshuab, thiab tshuab engraving, hloov cov cuab yeej ntsuas ib txwm muaj xws li cov kav thiab daim duab peb sab los txhim kho kev ua haujlwm thiab raug.

Nyob rau hauv kev tsim tsheb, 635 nm liab lasers yog siv rau lub cev ib feem, kom ntseeg tau qhov tseeb ntawm cov txheej txheem sib dhos.

Nyob rau hauv lub neej niaj hnub, 635/650 nm liab lasers yog ubiquitous-los ntawm laser pointers thiab barcode scanners nyob rau hauv lub khw loj mus rau qib laser rau kev tsim kho thiab laser pointers rau kev kawm. Lawv kuj tau siv rau hauv kev tiv thaiv thiab kev siv tub rog, xws li cov khoom siv laser pom, thiab hauv kev saib xyuas ib puag ncig rau kev kuaj pom muaj kab mob.

Vim lawv cov nqi qis thiab ntau yam kev siv, 635/650 nm liab lasers muaj kev lag luam loj tshaj plaws nyob rau hauv lub ntiaj teb no pom laser lag luam, nrog rau muaj zog thov nyob rau hauv ob qho tib si kev lag luam thiab cov neeg siv khoom lag luam.
