Kev ua haujlwm siab ultrafast waferlaser tshuab
Siab zogultrafast lasersyog dav siv nyob rau hauv advanced manufacturing, ntaub ntawv, microelectronics, biomedicine, lub teb chaws tiv thaiv thiab tub rog teb, thiab cov kev tshawb fawb txog kev tshawb fawb tseem ceeb heev los txhawb lub teb chaws scientific thiab technology innovation thiab high-zoo kev loj hlob. Nyias nyiaslaser systemnrog nws qhov zoo ntawm lub zog nruab nrab, loj mem tes zog thiab zoo beam zoo muaj kev xav tau zoo hauv attosecond physics, cov khoom siv thiab lwm yam kev tshawb fawb thiab kev lag luam, thiab tau muaj kev txhawj xeeb los ntawm cov teb chaws thoob plaws ntiaj teb.
Tsis ntev los no, ib pab neeg tshawb fawb hauv Suav teb tau siv tus kheej tsim wafer module thiab regenerative amplification technology kom ua tau zoo (siab stability, siab zog, siab beam zoo, high efficiency) ultra-ceev wafer.lasertso zis. Los ntawm kev tsim ntawm lub regeneration amplifier kab noj hniav thiab tswj qhov kub thiab mechanical stability ntawm lub disc siv lead ua nyob rau hauv kab noj hniav, lub laser tso zis ntawm ib tug mem tes zog> 300 μJ, mem tes dav <7 ps, nruab nrab zog> 150 W yog tiav. , thiab qhov siab tshaj plaws-rau-lub teeb hloov dua siab tshiab tuaj yeem ncav cuag 61%, uas tseem yog qhov kev hloov kho qhov muag tau tshaj plaws tau tshaj tawm txog tam sim no. Cov kab teeb pom kev zoo M2<1.06@150W, 8h stability RMS <0.33%, qhov kev ua tiav no yog qhov tseem ceeb hauv kev ua haujlwm siab ultrafast wafer laser, uas yuav muab tau ntau dua rau kev siv lub zog ultrafast laser.
High repetition zaus, siab zog wafer regeneration amplification system
Cov qauv ntawm wafer laser amplifier yog pom nyob rau hauv daim duab 1. Nws muaj xws li ib tug fiber ntau qhov chaw, ib tug nyias slice laser taub hau thiab ib tug regenerative amplifier kab noj hniav. Ib qho ytterbium-doped fiber oscillator nrog lub zog nruab nrab ntawm 15 mW, nruab nrab wavelength ntawm 1030 nm, pulse dav ntawm 7.1 ps thiab qhov rov ua dua ntawm 30 MHz tau siv los ua cov noob qoob loo. Lub taub hau laser wafer siv lub tsev tsim Yb: YAG siv lead ua nrog txoj kab uas hla ntawm 8.8 hli thiab tuab ntawm 150 µm thiab 48-stroke twj tso kua mis. Lub twj tso kua mis siv lub xoom-phonon kab LD nrog 969 nm ntsuas phoo wavelength, uas txo cov quantum defect rau 5.8%. Cov qauv cua txias tshwj xeeb tuaj yeem ua kom txias lub wafer siv lead ua thiab ua kom muaj kev ruaj ntseg ntawm cov kab noj hniav. Lub regenerative amplifying kab noj hniav muaj Pockels hlwb (PC), Thin Film Polarizers (TFP), Quarter-Wave Phaj (QWP) thiab ib tug high-stability resonator. Isolators yog siv los tiv thaiv lub teeb pom kev zoo los ntawm kev thim rov qab-ua rau cov noob qoob loo. Ib qho kev sib cais cov qauv uas muaj TFP1, Rotator thiab Ib Nrab-Wave Phaj (HWP) yog siv los cais cov noob tawm tswv yim thiab cov pulses amplified. Cov noob mem tes nkag mus rau hauv lub regeneration amplification chamber ntawm TFP2. Barium metaborate (BBO) crystals, PC, thiab QWP ua ke los tsim ib qho kev hloov kho qhov muag uas siv lub zog hluav taws xob mus sij hawm ntev rau PC kom xaiv cov noob mem tes thiab nthuav tawm nws rov qab thiab tawm hauv kab noj hniav. Qhov xav tau mem tes oscillates nyob rau hauv kab noj hniav thiab yog amplified zoo thaum lub sij hawm mus ncig teb chaws propagation los ntawm finely kho lub compression lub sij hawm ntawm lub thawv.
Lub wafer regeneration amplifier qhia tau hais tias cov khoom siv tau zoo thiab yuav ua lub luag haujlwm tseem ceeb hauv high-end manufacturing fields xws li ultraviolet lithography, attosecond twj tso kua mis, 3C electronics, thiab lub zog tshiab tsheb. Nyob rau tib lub sijhawm, wafer laser thev naus laus zis yuav tsum tau siv rau lub zog loj lojcov khoom siv laser, muab kev sim tshiab txhais tau tias rau kev tsim thiab nrhiav kom zoo ntawm cov teeb meem ntawm nanoscale qhov chaw teev thiab femtosecond time scale. Nrog rau lub hom phiaj ntawm kev pabcuam cov kev xav tau loj hauv lub tebchaws, pab pawg ua haujlwm yuav txuas ntxiv tsom mus rau laser thev naus laus zis kev tsim kho tshiab, ntxiv kev tawg los ntawm kev npaj cov tswv yim muaj zog laser muaj zog, thiab ua kom muaj txiaj ntsig zoo rau kev tshawb fawb ywj pheej thiab txhim kho lub peev xwm ntawm cov cuab yeej laser hauv thaj chaw ntawm cov ntaub ntawv, lub zog, cov khoom siv high-end thiab lwm yam.
