    Changchun Institute of Optics Proposes New Stress-Induced Nano-Shaping Method Using Direct Laser Writing

    A team led by Academician Zhang Xuejun at the Changchun Institute of Optics, Fine Mechanics and Physics published a paper in Laser & Photonics Reviews, proposing direct writing of amorphous silicon thin films with femtosecond lasers below the ablation threshold, using residual stress from solid-phase transformation to form controllable nanoscale surface topography.
