Lub tes tuav laser vuam tshuab yog cov khoom siv hlau tseem ceeb ntawm cov khoom siv vuam siv tam sim no, thiab ntau thiab ntau lub chaw tsim khoom pib yuav ntau lub tes tuav laser vuam tshuab siv.Txawm li cas los xij, txawm hais tias cov cuab yeej nws tus kheej muaj kev ua tau zoo heev, ob lub ntsiab lus no yuav tsum tau them sai sai rau thaum siv lub tshuab xuas tes tuav laser vuam.Ob lub ntsiab lus yog dab tsi?Cia peb saib!
Ob lub ntsiab lus no yuav tsum tau muab sau tseg thaum siv lub tes tuav laser vuam tshuab:
1, mem tes waveform
Pulse waveform yog ib qho teeb meem tseem ceeb hauv tes tuav laser vuam tshuab, tshwj xeeb tshaj yog nyob rau hauv laser ntawv vuam;Thaum lub teeb ci qis qis mus txog cov khoom siv saum npoo av, qee lub zog ntawm cov hlau saum npoo yuav tawg thiab ploj, thiab cov coefficient ntawm kev xav yuav hloov nrog qhov kev hloov ntawm qhov kub thiab txias.Thaum lub sij hawm lub sij hawm mem tes, qhov kev xav ntawm cov hlau hloov tau zoo heev, thiab cov mem tes dav yog ib qho tseem ceeb ntawm laser vuam.
2, zog ceev
Lub zog ceev yog lwm qhov tseem ceeb hauv laser vuam.Nyob rau hauv lub zog siab ceev, cov khoom nto tuaj yeem ncav cuag qhov kub thiab txias hauv microseconds, ua rau ntau melting.Lub zog ceev ceev yog qhov tsim nyog rau kev tshem tawm cov ntaub ntawv, xws li drilling, segmentation thiab engraving.Rau siab zog ceev, qhov kub ntawm qhov chaw tuaj yeem ncav cuag qhov kub hauv milliseconds;Tom qab qhov saum npoo yog melted los ntawm tes tuav laser vuam tshuab, hauv qab txheej mus txog qhov melting point los tsim ib tug zoo fusion vuam.Yog li ntawd, nyob rau hauv lub insulator laser vuam, lub zog ceev yog 104 ~ 106Wcm2.Lub zog ceev ntawm qhov nruab nrab ntawm qhov chaw laser yog tsawg dhau los ua kom evaporate rau hauv qhov.Nyob rau hauv lub dav hlau ze ntawm lub laser tsom, lub hwj chim ceev yog symmetrical.Muaj ob hom defocusing: zoo defocusing thiab tsis zoo defocusing.
Cov saum toj no yog cov ntsiab lus tseem ceeb uas yuav tsum tau them sai sai rau thaum siv lub tes tuav laser vuam tshuab.Feem ntau, peb yuav tsum debug thiab paub meej tias ob lub ntsiab lus no ua ntej siv.Kev ua haujlwm raug cai tsuas yog ua tau tom qab kev debugging thiab kom ntseeg tau tias tsis muaj qhov yuam kev.
