Principles of supersymmetry have been used to boost the performance of an array of solid-state lasers. The work was led by Mercedeh Khajavikhan at the University of Central Florida in the US. Her team ...

Recently, the research groups led by Prof. Zhang Qingli and Prof. Jiang Haihe from Hefei institutes of Physical Science ...

Researchers have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating.

“The optical stamping process allows this problem to be circumvented,” said Sönke Vogel from the Micro and Nano Structuring ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

Terahertz radiation is used for security checks at airports, for medical examinations and also for quality checks in industry. However, radiation in the terahertz range is extremely difficult to ...
