Iron Triangle releases fiber Bragg gratings and arrays based on multi-core fibers

The Chinese Academy of Sciences reduced the volume of the deep ultraviolet laser by 90% and achieved 193 nm vortex beam output for the first time. Professor Xuan Hongwen described "loading truck equipment into the car trunk". This technology enables a 30% reduction in the size of lithography features, breaking through the bottleneck of the 2-nanometer process. In the next three years, laser power ...

In a groundbreaking scientific study published in Volume 13 of the Scientific Report, researchers reported on the results of Young's double slit interference experiment using oscillating vortex radiation under a photon counting system. The experiment involves using a spiral oscillator to emit second harmonic radiation in the ultraviolet range. Using an ultra narrow bandpass filter in the low curre...

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...

It is reported that recently researchers from the Chinese Academy of Sciences have achieved the highest power output of 193 nm and 221 nm lasers using lithium borate (LBO) crystals. This achievement lays the foundation for the further application of the laser in deep ultraviolet (DUV) spectroscopy.The laser in DUV spectroscopy has many applications in science and technology, such as defect detecti...

Cinemas are in a developmental stage. Their roles are changing and the rules are being rewritten. Many people have proposed a way to make cinemas a truly unique place by providing audiences with a higher quality experience. It is along this route that UCI Cinemas continues to move forward. In recent days, it has officially launched a 4K laser projector and had a special date with the new MCU movie...
