1.54μm / 1535nm Qhov muag -Safe Laser Teeb Source

Lub 1.54 μm microchip DPSS laser yog ib qho khoom siv - lub xeev laser nrog ib lub wavelength tshwj xeeb, nws lub qhov muag - nyab xeeb wavelength thiab compact tag nrho - khoom - xeev tsim. Cov yam ntxwv no ua rau nws tseem ceeb hauv ntau qhov chaw tseem ceeb:

I. Cov ntsiab lus zoo thiab cov ntsiab lus

Qhov muag kev nyab xeeb: Lub 1.54 μm wavelength ntog nyob rau hauv lub zog nqus dej. Feem ntau ntawm lub zog laser yog absorbed los ntawm aqueous lom zem thiab lo ntsiab muag nyob rau hauv lub anterior ib feem ntawm lub qhov muag ua ntej mus txog lub retina, zoo heev txo qhov kev pheej hmoo ntawm mus tas li retinal puas. Nws qhov siab tshaj plaws raug tso cai yog ntau qhov kev txiav txim siab ntau dua li ntawm 1064nm lasers, ua rau nws qib kev nyab xeeb zoo dua li lasers ze 1 μm.

Microchip DPSS Technology: Ib qho me me nti ua ke nrog lub laser siv lead ua (xws li Er: Yb: iav) thiab cov siv lead ua tsis sib xws (xws li PPLN) yog siv los ntawm lub laser diode kom ncaj qha tsim 1.54 μm laser teeb. Qhov kev tsim no ua rau lub tshuab me me, cov qauv muaj zog, kev ua haujlwm siab, thiab kev txij nkawm- ua haujlwm dawb.

II. Cov cheeb tsam tseem ceeb ntawm daim ntawv thov

1. Lidar thiab Ranging

Hauv kev cob qhia, kev tawm dag zog, thiab tsawg - ib puag ncig kev pheej hmoo, nws txo qis qhov kev pheej hmoo ntawm qhov muag raug mob rau cov neeg ua haujlwm thiab cov koom haum phooj ywg.

Kev Lag Luam thiab Kev Tshawb Fawb: Siv rau siab -kev ua lag luam muaj tseeb, kev soj ntsuam thaj chaw, thiab kev zam ntawm drone obstacles, muab kev nyab xeeb rau kev ua haujlwm hauv ib puag ncig nrog tib neeg.

Autonomous Tsav Tsheb: Raws li ib qho ntawm cov teeb pom kev zoo rau lidar, nws muaj peev xwm hauv kev sim pej xeem txoj kev thiab kev siv yav tom ntej uas qhov kev xav tau kev nyab xeeb ntawm qhov muag siab heev.

2. Pub dawb -Space Optical Communication

Tub Rog Kev Sib Txuas Lus: Siv rau kev ruaj ntseg cov ntaub ntawv txuas ntawm cov chaw nres tsheb hauv av, nkoj, lossis huab cua - mus rau - kev sib txuas lus hauv av. Lub 1.54 μm wavelength muaj cov yam ntxwv ntawm atmospheric kis tau tus mob zoo (attenuation yog qis dua 1.55 μm kev sib txuas lus wavelength, tab sis deb tshaj qhov pom lub teeb), thiab cov nqaj tsis tshua muaj kev cuam tshuam, muaj zog tiv thaiv kev cuam tshuam thiab cuam tshuam.

Civilian Emergency thiab Private Network Kev Sib Txuas Lus: Siv nyob rau hauv cov xwm txheej uas xav tau kev xa tawm sai, bandwidth siab, thiab qhov twg wireless xov tooj cua zaus txwv lossis tsis muaj.

3. Kev soj ntsuam ib puag ncig thiab Spectroscopy

Differential Absorption Lidar: Siv cov kab nqus cov pa roj xws li dej vapor thiab methane nyob ze 1.54 μm, nws remotely ntes thiab ntsuas qhov concentration ntawm cov khoom no nyob rau hauv cov huab cua, siv rau kev tshawb fawb huab cua, tshuaj xyuas cov pa hauv tsev cog khoom, thiab cov pa phem qhov chaw tracing.

Laser-Induced Breakdown Spectroscopy: Siv los ua qhov zoo siab hauv LIBS daim ntawv thov xav tau qhov chaw ua haujlwm zoo dua.

4. Kev tshawb fawb thiab kev sim

Laboratory Light Source: Raws li tus qauv teeb pom kev zoo ntawm lub qhov muag- nyab xeeb wavelength, siv rau kev sim kho qhov muag, ntsuas ntsuas ntsuas, thiab kev tshawb fawb ntawm huab cua kis tus yam ntxwv.

Kev Ntsuas thiab Kev Ntsuas: Siv los ntsuas thiab ntsuas qhov ua tau zoo ntawm lwm lub tshuab kho qhov muag (xws li lub koob yees duab infrared thiab cov khoom ntes).

5. Kev Kho Mob thiab Bioimaging (Kev Tshawb Fawb Kev Siv)

Optical Coherence Tomography: Hauv OCT thev naus laus zis, 1.54 μm wavelength tuaj yeem muab cov ntaub so ntswg tob tob (piv rau 1300nm qhov rais), haum rau dermatology lossis kev tshawb fawb ntawm qee cov ntaub so ntswg sib sib zog nqus.

Kev pab phais thiab kev kho mob: Nws nqus dej ua rau nws tsim nyog rau qee qhov kev phais cov nqaij mos.

Cov ntsiab lus
Cov ntawv thov tseem ceeb ntawm 1.54 μm microchip DPSS lasers yog tsom rau hauv cov khoom siv optoelectronic nrog cov kev xav tau siab heev rau qhov muag kev nyab xeeb, tshwj xeeb tshaj yog cov tub rog / kev ruaj ntseg laser ntau yam thiab dawb -qhov chaw sib txuas lus optical. Nws zoo kawg nkaus ua ke nrog kev ntseeg siab ntawm DPSS thev naus laus zis nrog qhov muaj kev nyab xeeb thiab zoo heev ntawm huab cua kis tau tus yam ntxwv ntawm 1.54 μm wavelength, ua rau nws nyiam lub teeb pom kev hauv cov ntawv thov kev tshaj lij.

Nws daim ntawv "microchip" ntxiv txhawb nqa miniaturization, kev siv hluav taws xob tsawg, thiab cov khoom siv ntau lawm, ua rau nws tuaj yeem ua ke rau hauv cov platforms niaj hnub xws li cov khoom siv portable, drones, thiab satellite kev sib txuas lus terminals.Cov lus teb no tau tsim los ntawm AI thiab tsuas yog siv rau kev siv xwb. Thov xyuas cov ntaub ntawv kom zoo.

Puas yog 1.54 μm thiab 1535nm tib yam khoom?

Qhov no yog ib lo lus nug uas tshaj lij thiab meej.

Cov lus teb yooj yim thiab ncaj qha yog: nyob rau hauv feem ntau cov kev siv thiab cov ntsiab lus ntawm cov khoom, yog, lawv xa mus rau tib yam. Txawm li cas los xij, nruj me ntsis hais lus, muaj qhov sib txawv me ntsis technically. Cov hauv qab no yog cov lus piav qhia ntxaws:

1. Qhov tseem ceeb taw tes rau tib lub wavelength band (√ Core sib xws)

Hauv thaj chaw ntawm lasers thiab fiber optic kev sib txuas lus, ob qho tib si 1.54 μm (micrometers) thiab 1535 nm (nanometers) xa mus rau lub wavelength ze ntawm C-band (paj band) nyob nruab nrab ntawm 1540 nanometers.

Kev sib raug zoo ntawm kev hloov pauv: 1 μm=1000 nm, yog li 1.54 μm=1540 nm.

Kev ua lag luam:

Hauv thaj chaw ntawm lidar, rangefinding, thiab kev siv tub rog, feem ntau yog siv lub "micrometer", xws li 1.54 μm lossis 1.55 μm, kom xa mus rau qhov "qhov muag- nyab xeeb wavelength."

Hauv kev sib txuas lus ntawm fiber ntau optic, nm yog siv los ua chav tsev nrog kev ua haujlwm siab heev, vim tias cov channel sib nrug ntawm DWDM systems tuaj yeem nqaim li 0.8 nm lossis 0.4 nm . 1530 nm -1565 nm yog qhov tseem ceeb ntawm C-band.

Yog li ntawd, thaum koj pom ib yam khoom uas sau tias 1.54 μm DPSS laser, nws cov zis wavelength tiag tiag yuav nyob nruab nrab ntawm 1530 nm thiab 1550 nm . 1535 nm tuaj yeem suav hais tias yog ib tus nqi wavelength tshwj xeeb hauv qhov ntau.

2. Kev sib txawv me ntsis (△ Qhov tseeb qhov sib txawv)

1.54 μm yog ib qho kev qhia dav dav. Nws dav sawv cev rau lub laser "ze 1540 nanometers." Vim muaj yam xws li Er (erbium) ion lub zog hloov pauv thiab siv lead ua doping, cov zis ntawm DPSS lasers feem ntau muaj qhov bandwidth me me (xws li ob peb nanometers), thiab qhov nruab nrab wavelength kuj yuav hloov me ntsis ntawm 1540 nm.

1535 nm yog qhov tseeb dua thiab meej tus nqi wavelength. Nws yuav txhais tau tias:

Lub laser yog tsim los kom nws cov zis wavelength yog xauv rau qhov tseeb heev point ntawm 1535 nm (piv txwv li, kom phim ib tug tshwj xeeb gas nqus kab rau sensing).

Nyob rau hauv fiber optic kev sib txuas lus DWDM systems, 1535 nm yog ib qho ntawm cov qauv raws.

3. Vim li cas lawv thiaj suav tau tias yog tib yam hauv cov ntsiab lus ntawm koj cov khoom (1.54 μm Microchip DPSS Laser)?

Zoo tib yam Eye Safety Mechanisms: Ob leeg 1540nm thiab 1535nm wavelengths poob rau hauv lub zog nqus dej, sib koom cov yam ntxwv tseem ceeb ntawm "qhov muag kev nyab xeeb." Cov qauv kev nyab xeeb (xws li IEC 60825) tau txiav txim siab rau ntau qhov kev sib tw, thiab cov qhab no yog ib qho ntawm cov kev nyab xeeb tshaj plaws.

Kev Ua Raws Li Kev Ua Haujlwm: Ob leeg yog tsim los ntawm tib lub cev lub cev - siv lub laser diode los tso cov erbium-doped (los yog erbium-ytterbium co-doped) nce nruab nrab (crystal lossis iav), ua lub teeb ze ntawm 1.55 μm los ntawm kev tawm dag zog. Tus tsim microchip tsuas yog ib daim ntawv ntim khoom xwb.

Kev sib tshooj ntau heev: Ob leeg 1540nm thiab 1535nm feem ntau yog siv rau hauv thaj chaw uas xav tau kev nyab xeeb thiab kev ntseeg siab, xws li laser ntau, LiDAR, thiab dawb -chaw kho qhov muag. Daim ntawv thov tshuab feem ntau tsis pom zoo rau qhov sib txawv ntawm ob peb nanometers.

Peb nyob nraum kev 1.54 μm microchip dpss laser manufacturers thiab lwm tus neeg nyob hauv Suav teb, tshwj xeeb hauv kev muab cov khoom zoo thiab cov kev pabcuam. Peb sov siab txais tos koj rau cov lag luam wholesale pheej yig 1.54 μm microchip dpss laser rau muag ntawm no los ntawm peb lub hoobkas. Tsis tas li, kev pabcuam customized muaj.
