Laser tu, tseem hu ua laser tshem tawm cov ntaub ntawv los yog laser ablation, yog ib qho kev tu siab heev uas siv lub siab - lub zog laser beam kom irradiate nto ntawm ib tug workpiece, ua rau nto kab mob xws li xeb, coatings, thiab roj kom evaporate los yog tev tawm tam sim ntawd. Cov thev naus laus zis no yog tus cwj pwm los ntawm kev ua tsis yog- abrasive, tsis yog -kev sib cuag, tsis yog - puas tsuaj rau substrate, thiab ib puag ncig tus phooj ywg.
Xyoo 1965, Nobel laureate Arthur Schawlow tau tshawb pom tias tus number case vaporized thiab ploj mus thaum cov ntawv luam tawm tau irradiated nrog lub laser pulsed, thawj lub tswv yim ntawm "laser erasure." Xyoo 1969, SM Bedair thiab lwm tus tau sim siv lasers kom tshem tawm cov pa oxygen thiab sulfur paug los ntawm cov khoom siv nickel. Xyoo 1973, Asmus pab pawg tshawb fawb tau tshaj tawm cov kev sim ntawm laser ntxuav cov duab kos duab. Nyob rau hauv 1987, Zapka tau thov rau thawj patent ntawm laser tu nyob rau hauv lub teb chaws Yelemees, thiab nyob rau hauv tib lub xyoo, cov kev tshawb fawb pab pawg neeg ntawm Soviet kws tshawb fawb Petrov luam tawm thawj daim ntawv lees paub ntawm laser tu microparticles. Laser tu tshuab tau siv rau hauv kev lag luam xws li chip manufacturing, xeb tshem tawm hauv cov dav hlau thiab nkoj, kho cov khoom qub, kho pwm, thiab kev tsim tsheb thauj mus los.
