Nowadays, lasers that emit extremely short flashes can be found in many research laboratories, but they usually fill the entire room. Physicists have now successfully reduced this laser to the size of a computer chip. As they reported in the journal Science, their research can lay the foundation for extremely compact detectors.A team led by Qiushi Guo from the California Institute of Technology in...
The femtosecond laser emits ultra short optical pulses with a duration of less than one picosecond, reaching the femtosecond level (1fs=10-15s). The characteristics of femtosecond laser are extremely short pulse width and high peak intensity.Ultra short pulse trains can minimize residual heat, ensure precise material processing, and minimize incidental damage. Its high peak intensity can induce no...
Particle physicists have detected for the first time a new decay of the Higgs boson, revealing subtle differences predicted by the standard model and potentially pointing to new physics beyond it. The research results are published in the journal Physical Review Letters.The theoretically predicted Higgs boson since the 1960s was finally discovered in the European CERN laboratory in 2012. As a quan...
For centuries, people have known that light exhibits wave like behavior in certain situations. When light passes through certain materials, they can change the polarization of light waves (i.e. the direction of oscillation). The core components of optical communication networks, such as optical isolators or photodiodes, utilize this characteristic. This type of component allows light to propagate ...
BAE Systems Australia has successfully conducted experiments at the Osborne Naval Shipyard and Henderson Shipyard, using laser scanning technology to create 3D models of pipelines that will be installed on the currently under construction Hunter class frigates.A one week trial was conducted at the Zero Line Future factory in southern Adelaide and BAE Systems Australia's Henderson Shipyard, demonst...
