Tam sim no, iav sawv tawm raws li thaj chaw loj nrog tus nqi ntxiv thiab muaj peev xwm rau batch laser ua daim ntawv thov. Femtosecond laser thev naus laus zis yog ib qho kev txhim kho kev ua haujlwm sai heev nyob rau xyoo tas los no, nrog rau kev ua haujlwm siab heev thiab ceev, muaj peev xwm ntawm micrometer mus rau nanometer-theem etching thiab ua rau ntau yam khoom siv (xws li iav laser ua).
