A method for fabricating deep grating structures on a silicon carbide (SiC) surface by a femtosecond laser and chemical-selective etching is developed. Periodic lines corresponding to laser-induced structure change (LISC) are formed by femtosecond la
A method of multi-beam femtosecond laser irradiation combined with modified HF-HNO3-CH3COOH etching is used for the parallel fabrication of all-silicon plano-concave microlens arrays (MLAs). The laser beam is split by a diffractive optical element an
The effects of laser irradiation on erythrocyte deformability and related mechanism were investigated. Membrane attached hemoglobin (Hbm) is the determinant factor of erythrocyte deformability. After irradiation of 532 nm (30 mW, 20 minutes) or 632.8
Near infrared to ultraviolet (UV) and visible upconversion luminescence was observed in ZnO single crystalline under femtosecond laser irradiation. The optical properties of the crystal reveal that the UV and visible emission band are due to the exci
Fourier transform infrared spectroscopy (FTIR) was employed to study the human epidermis larynx carcinoma cell lines (Hep-2) which were irradiated by different doses of X-ray. The results show that (1) the irradiation of X-ray damages the structure o
The femtosecond laser induced void array inside Al2O3 crystals was discussed. The void array was formed spontaneously under the irradiation of a single beam of infrared femtosecond laser which was focused at a fixed point inside the Al2O3 crystal sam
Light dose plays an important role in the non-ablative photorejuvenation based on the theory of selective photothermolysis. However, present techniques for determining the light dose in clinical practice are still not accurate enough. We present a ne
Using the optical coherence tomography (OCT) images, the optical attenuation coefficients (\mu t) of human Laogong acupoint and non-acupoint tissues are measured after empty irradiation and 808-nm 100-mW irradiation for 10 min in vivo non-invasively.
Au nanoparticles were precipitated inside Au+-doped glass samples after irradiation by femtosecond laser or x-ray. Femtosecond laser and X-ray irradiation result in decreasing of anneal temperature and critical size for the precipitation of Au nanopa
