Yuav Ua Li Cas Xaiv Cov Khoom Laser Zoo?

Txij li thaum lub sij hawm tshwm sim ntawm lub ntiaj teb thawj laser nyob rau hauv 1960,Laserstau nkag mus rau hauv ntau yam xws li kev tsim khoom, kev tshawb fawb tshawb fawb, kev kho mob, thiab lub neej txhua hnub. Hauv ntau daim ntawv thov, qhov tsis muaj ntawm lub laser ncaj qha txiav txim siab tus neeg siv qhov kev xaiv ntawm lub teeb laser. JTBYShield tau muab tso ua ke ib co parameter txhais ntawm cov pa lasers thiab piav luv luv lawv ntawm no rau koj siv. Peb cia siab tias yuav pab koj nrhiav tau cov khoom laser uas haum koj lub sijhawm luv tshaj plaws.

1. Tso zis zog

Zoo li hluav taws xob hluav taws xob, lub teeb tawm los ntawm lub laser kuj yog lub zog, tab sis nws tshwm nyob rau hauv daim ntawv ntawm lub teeb lub zog. Yog li ntawd, lub zog tso zis ntawm lub laser yog tib yam li cov zis hluav taws xob ntawm lub tshuab hluav taws xob cog hluav taws xob. Nws yog lub cev kom muaj nuj nqis uas ntsuas lub zog laser tawm ib lub sijhawm. Cov ntsuas ntsuas feem ntau yog milliwatt (mW), watt (W), kilowatt (kW), thiab lwm yam.

2. Lub zog ruaj khov

Lub zog ruaj khov sawv cev rau qhov tsis muaj zog ntawm laser tso zis hluav taws xob nyob rau hauv ib lub sij hawm ntawm lub sij hawm, uas feem ntau muab faib ua RMS stability thiab ncov-rau-peak stability.
Dab tsi yog qhov txawv ntawm RMS stability thiab peak-rau-peak stability?
RMS stability: qhov piv ntawm lub hauv paus txhais tau tias square ntawm tag nrho cov piv txwv ntawm lub hwj chim qhov tseem ceeb thaum lub sij hawm xeem lub sij hawm mus rau qhov nruab nrab lub hwj chim tus nqi, piav qhia txog cov degree ntawm dispersion ntawm lub tso zis hwj chim los ntawm qhov nruab nrab hwj chim tus nqi. Ntawm CNI laser lub vev xaib, lub zog laser ruaj khov yog RMS ruaj khov hauv 4 teev.
Peak-rau-peak stability: qhov feem pua ​​​​ntawm qhov sib txawv ntawm tus nqi siab tshaj plaws thiab qhov tsawg kawg nkaus tus nqi ntawm cov zis hluav taws xob thiab qhov nruab nrab lub hwj chim tus nqi, uas sawv cev rau qhov sib txawv ntawm cov zis hluav taws xob hauv ib lub sijhawm.

3. Beam quality factor (M2 factor)
Lub beam zoo tshaj plaws yog txhais raws li qhov piv ntawm cov khoom ntawm lub laser beam duav vojvoog thiab lub beam deb-field divergence lub kaum sab xis rau cov khoom ntawm lub hom phiaj zoo tagnrho beam duav vojvoog thiab lub hom phiaj divergence lub kaum sab xis, uas yog.

Yuav ua li cas ntsuas qhov superiority ntawm beam zoo yam?
Beam zoo yuav cuam tshuam rau cov nyhuv tsom ntawm lub laser thiab qhov chaw faib khoom hauv thaj tsam deb. Nws yog ib qho parameter siv los qhia qhov zoo ntawm lub laser beam. Qhov ze dua qhov tseeb laser beam zoo tshaj plaws yog rau 1, qhov ze ntawm lub beam zoo yog mus rau lub beam zoo tagnrho, thiab qhov zoo ntawm lub beam zoo yuav yog. zoo. CNI laser semiconductor-pumped solid-state laser beam zoo yam yuav ua tau zoo dua 1.1.

4. Lub teeb Spot (transverse hom)
Qhov chaw ruaj khov kev faib tawm ntawm ib qho kev hla ntu perpendicular mus rau laser propagation kev taw qhia yog hu ua transverse hom. Qhov chaw laser sawv cev rau transverse hom faib. Lub transverse hom faib yog simulated los ntawm CCD array kom tau txais ib co beam yam ntxwv ntawm lub laser, raws li qhia nyob rau hauv daim duab. Cov hauv qab no qhia txog qhov xwm txheej ntawm TEM00 Gaussian beam.

Ntxiv rau qhov tseem ceeb hloov pauv hom (TEM00), muaj lwm hom, raws li qhia hauv qab no:

5. Spot Diameter
Rau kev ntsuas ntawm qhov chaw txoj kab uas hla, feem ntau yog trepanation txoj kev, riam ntug txoj kev, laser profile analyzer (CCD) ntsuas, thiab lwm yam.

Txoj kev Trench qhov:Txij li thaum nws yog ib qho nyuaj rau ua tiav concentricity ntawm lub qhov thiab cov nqaj nyob rau hauv kev sim, qhov tseeb yog ib qho nyuaj rau lav.
Laser profile analyzer (CCD) kuaj:Nws tuaj yeem ua kom qhov tseeb ntawm qhov ntsuas ntsuas. Qhov chaw txoj kab uas hla hauv software interface tuaj yeem muab cov txiaj ntsig ntawm plaub txoj kev ntsuas (saib daim duab 3), uas feem ntau siv ib qho yog 13.5% ntawm tus nqi siab tshaj (1 / e2) yog txoj kev ciam teb. Txawm hais tias txoj kev sim no muaj qhov raug siab, rau lub zog lasers siab, CCD muaj qhov tshwm sim saturation. Yog tias siv lub attenuator, nws tuaj yeem ua rau beam distortion.
Riam ntug txoj kev:Nws yog ib txoj hauv kev zoo tshaj plaws rau kev ntsuas qhov chaw txoj kab uas hla ntawm high-power lasers. Siv lub riam ntug txoj hauj lwm tswj x1 qhov twg lub teeb lub zog ntawm lub laser yuav tsum tau ntsuas dhau los ntawm riam ntug ntug thiab tso nyiaj rau 10% ntawm tag nrho cov hwj chim. Siv lub riam ntug txoj hauj lwm tswj x2 qhov twg lub teeb lub zog ntawm lub laser yuav tsum tau ntsuas dhau los ntawm riam ntug nyiaj rau 90% ntawm tag nrho cov hwj chim. Spot diameter=1.561 ×|x1- x2|(qhov twg 1.561 yog tus nqi haum).

Riam Ntug Method rau Ntsuas Spot Diameter

Puas yog lub teeb me me?
Thaum ntsuas qhov chaw txoj kab uas hla ntawm lub teeb pom kev nrog tus pas ntsuas lossis tib neeg lub qhov muag, vim li cas lub laser qhov chaw txoj kab uas hla tau loj dua qhov ntsuas uas siv lub tshuab ntsuas qhov profile?
Qhov no yog vim lub zog laser muaj zog thiab muaj zog, thiab yuav diverge mus rau ib qho twg thaum nws ua rau cov khoom. Thaum siv qhov chaw ntsuas qhov ntsuas qhov ntsuas, qhov chaw ntawm qhov chaw ntawm qhov siab tshaj plaws (13.5%) taw tes yog feem ntau siv los ntsuas qhov tshwm sim, yog li qhov ntsuas tau txais yuav me me.

6. Laser Modulation
Laser modulation siv lub teeb ua tus cab kuj thauj cov teeb liab mus rau lub teeb thiab ua tiav cov teeb liab kis tau tus mob raws li daim ntawv thov. Feem ntau, kev hloov pauv tau muab faib ua cov qauv sab nraud thiab sab hauv kev hloov kho. Sab nrauv modulation yog hais txog kev hloov kho tshuab lossis acoustic-optical modulation ua sab nraum lub laser; internal modulation yog hais txog lub hwj chim-tsav modulation. Sab hauv kev hloov pauv tau muab faib ua TTL kev hloov pauv thiab kev hloov pauv analog, raws li pom hauv daim duab. Yellow CH1 yog qhov hluav taws xob input waveform, thiab xiav CH2 yog modulated optical waveform.

TTL kev hloov kho: Thaum qib siab thiab qis (0V lossis 5V) DC lub teeb liab ntawm qee zaus yog nkag mus rau sab nraud laser, lub teeb raug kaw thaum qis qis siab, thiab lub zog tag nrho yog tso tawm. thaum lub siab siab. Lub siab amplitude tsis tuaj yeem hloov kho.
Analog modulation: Lub waveform thiab amplitude ntawm lub teeb liab input tuaj yeem hloov kho dawb, thiab lub zog hluav taws xob laser hloov linearly nrog cov teeb liab analog voltage input.
