    Sensitive detection of laser damage to Mo/Si multilayers by picosecond ultrasonics

    Picosecond ultrasonics is used to study the damage or degradation of Mo/Si multilayers caused by laser irradiation. Changes of surface phonon spectra in multilayers due to femtosecond laser damaging are observ...

    Fabrication of high-aspect-ratio sub-diffraction-limit microstructures by two-photon-absorption photopolymerization

    Micro-cell structures with side-walls as thin as 0.70 μm and aspect ratios as high as 6.7 are fabricated by single-layer writing through two-photon-absorption (TPA) photopolymerization. The use of a moderate-n...
