A team of researchers at the Chinese Academy of Sciences working with a colleague from ShanghaiTech University and another from Zhangjiang Laboratory, has developed a new way to make a laser with light in a wide range of ...
Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly different spiral shape, may ...
Physicists at The Australian National University (ANU) have developed extremely powerful microscopic lasers that are even smaller than the wavelength of the light they produce.
