Sub-micron machining of semiconductors - Femtosecond surface ripples on GaAs by 2 μm laser light
In recent years, a major interest in surface as well as bulk property modification of semiconductors using laser irradiation has developed. A.Kar et al. [1][2] and E.Mazur et al. [3] have shown introduction and control of dopants by long-pulse laser irradiation and increased absorption due to femtosecond irradiation respectively. With the development of mid-IR sources, a new avenue of irradiati...
متن کاملLaser-ultrasonic surface wave dispersion measurements on surface-treated metals.
Surface acoustic wave (SAW) velocity spectroscopy has been long considered to be one of the leading candidates for nondestructive characterization of surface-treated metals because of its ability to probe the material properties at different penetration depths depending on the inspection frequency. We developed a high-precision laser-ultrasonic technique to study the feasibility of SAW dispersi...
متن کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولLaser-induced plasmonic colours on metals
Plasmonic resonances in metallic nanoparticles have been used since antiquity to colour glasses. The use of metal nanostructures for surface colourization has attracted considerable interest following recent developments in plasmonics. However, current top-down colourization methods are not ideally suited to large-scale industrial applications. Here we use a bottom-up approach where picosecond ...
متن کاملLaser-induced periodic annular surface structures on fused silica surface
We report on the formation of laser-induced periodic annular surface structures (LIPASS) on fused silica irradiated with multiple femtosecond laser pulses. This novel morphology emerges after the disappearance of the conventional laser induced periodic surface structures (LIPSS), under successive laser pulse irradiation. It is independent of the laser polarization and universally observed for d...
