Laser processing is a relatively emerging non-contact processing method that utilizes the high energy of a beam of light to interact with materials and instantly vaporize or change their properties to achieve the expected manufacturing effect. It has gradually been promoted and applied in China in the past 20 years. Due to the different types, pulse widths, and wavelengths of laser generators, the...
Imagine being able to carry a 3D printer with you and quickly create low-cost objects, such as fastening bicycle wheels or parts needed for critical medical surgeries. Scientists from the Massachusetts Institute of Technology (MIT) and the University of Texas at Austin have combined silicon photonics and photochemical technology to successfully develop the first chip based 3D printer, taking a cru...
Scientists at the City University of New York use tiny nitrogen defects in the atomic structure of diamonds as "color centers" to write data for storage. This technology is published in the journal Nature Nanotechnology and allows for encoding multiple bytes of data into the same nitrogen defect at multiple optical frequencies, without confusing the information content.The common laser based techn...
Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
Recently, a joint research team composed of Sun Meizhi, associate researcher of the High Power Laser Physics Joint Laboratory of the Chinese Academy of Sciences Shanghai Institute of Optics and Precision Mechanics, and Tu Xiaoniu, associate researcher of the Chinese Academy of Sciences Shanghai Institute of Silicate, proposed a new configuration of cross Fabry Perot intracavity optical parametric ...
