The green and blue laser diode series provides higher beam quality

Summary:To filter out infrared light from the driving light source in the extreme ultraviolet lithography (EUVL) light source system, a rectangular grating structure needs to be fabricated on the surface of the collection mirror. However, the collection mirror grating usually undergoes deformation during the manufacturing process, resulting in a decrease in filtering efficiency. The process errors...

Introduction and application of a micro optical platform using metasurfacesMetasurfaces are artificial materials that excel in manipulating perception. Due to the fact that metasurfaces can reduce the size of lenses to one thousandth of traditional lenses, they have attracted great attention as optical components for miniaturization of next-generation virtual reality, augmented reality, and LiDAR ...

Due to advances in materials science by Stockholm researchers, changing the shape during flight to better handle airflow passing through its aircraft wings may be imminent. The trick involves the melting and drilling capabilities of lasers.Researchers from KTH Royal Institute of Technology in Stockholm, Sweden conducted experiments on paraffin. Using the 2D version of the material, they were able ...

RIKEN's two physicists have achieved extremely short laser pulses with a peak power of 6 terawatts (6 trillion watts) - roughly equivalent to the power generated by 6000 nuclear power plants. This achievement will contribute to the further development of attosecond lasers, for which three researchers were awarded the Nobel Prize in Physics in 2023. This study was published in the journal Nature Ph...

With the rise of clean energy and the enhancement of environmental awareness, thin film solar cells are gradually replacing traditional silicon-based solar cells as an efficient energy conversion device.However, to achieve efficient solar cell conversion rates, the key is to ensure that thin film solar cells have clear edges and maximize light absorption. In this regard, the unique advantages of h...
