What is the power of a beam of light? If light is used in the manufacturing field, its highest accuracy can reach one percent of the diameter of a hair thread, which is why it is called the "brightest light", "most accurate ruler", and "fastest knife". From airplanes and ships to kitchens and electrical appliances, lasers are widely used as advanced processing tools in all aspects of equipment man...
Two photon polymerization is a potential method for nanofabrication of integrated nanomaterials based on femtosecond laser technology. The challenges faced in the field of 3D nanoprinting include slow layer by layer printing speed and limited material selection due to laser material interactions.In a new report in Progress in Science, Chenqi Yi and a team of scientists in the fields of technical s...
Today, VCSELs (vertical cavity surface-emitting lasers) are used in everything from computer mice to face-scanning hardware in smart phones. They are renowned for their ability to integrate seamlessly into semiconductor chips, VCSELs are still considered to be an active field of research, and many researchers believe there are still important applications waiting to be discovered.The laboratory of...
