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...
Light can calculate functions during propagation and interaction with structured materials, with fast speed and low energy consumption. The use of all optical neural networks for general computing requires an optical activation layer with nonlinear dependence on the input. However, existing optical nonlinear materials either have slow speeds or very weak nonlinearity at the level of natural light ...
According to a report in Nature on June 26th, a team from Stanford University in the United States has developed a titanium sapphire laser on a chip. Whether in terms of scale efficiency or cost, this achievement is a huge progress. Image source: Nature websiteTitanium sapphire lasers are indispensable in many fields such as cutting-edge quantum optics, spectroscopy, and neuroscience, but they ...
