The ZEUS laser at the University of Michigan recently achieved a breakthrough of doubling the peak power of the strongest laser in the United States through its first 2 quadrillion watt experiment. Although this instantaneous power only lasts for 25 attosecond (one billionth of a second), it exceeds the total power of the global power grid by more than a hundred times.Karl Krushelnick, director of...
The optical properties of photonic crystals are closely related to their lattice constants, which are usually required to be in the same order of magnitude as the operating wavelength. In a crystal material, the photonic crystal structure is formed by the periodic arrangement in space of units whose dielectric constant is different from that of the crystal itself, and whose lattice constant depend...
Application backgroundLaser swing welding technology was born out of the urgent demand for welding quality and efficiency in modern manufacturing industry. Traditional welding technology has shortcomings in precision, strength, and complex structures, which has led to the rapid application of laser welding in various fields. However, it still has defects such as pores and cracks, and has limitatio...
With the help of on-chip accelerator technology, researchers at Stanford University are getting closer to manufacturing a miniature electron accelerator that can have various applications in industrial, medical, and physical research.Scientists have proven that silicon dielectric laser accelerators can now be used to accelerate and limit electrons, thereby producing concentrated high-energy electr...
