Pointing and tracking errors due to localized deformation in inter-satellite laser communication links

Optics Express, 2008
Instead of Zernike polynomials, ellipse Gaussian model is proposed to represent localized wave-front deformation in researching pointing and tracking errors in inter-satellite laser communication links, which can simplify the calculation. It is shown that both pointing and tracking errors depend on the center deepness h, the radiuses a and b, and the ...

One‐Step Synthesis of Size‐Controlled Copper Oxide Nanoparticles on Laser‐Induced Graphene Sensor for L‐Cysteine Detection

Advanced Electronic Materials, EarlyView.
Oxygen plasma treatment enhances polyimide hydrophilicity and promotes uniform anchoring of copper ion precursors. A one‐step laser process then generates CuO‐decorated nanoparticles on laser‐induced graphene (LIG) electrodes, enabling controlled nanoparticle growth via precursor concentration tuning.
