Latest Mode-locking Stories
Physicists have long chased an elusive goal: the ability to "freeze" and then study the motion of electrons in matter.
Whether surgeons slice with a traditional scalpel or cut away with a surgical laser, most medical operations end up removing some healthy tissue, along with the bad.
Researchers at MIT Media Lab are experimenting with giving a camera the ability to shoot pictures of objects that are not in its line-of-sight.
Ultrafast lasers, lasers that emit light pulses that are as short as a few femtoseconds, have enabled a wide-range of fundamental science and applications over the past two decades.
Researchers in applied physics have cleared an important hurdle in the development of advanced materials, called metamaterials, that bend light in unusual ways.
Researchers at Purdue University and the National Institute of Standards and Technology (NIST) have created a device small enough to fit on a computer chip that converts continuous laser light into numerous ultrashort pulses, a technology that might have applications in more advanced sensors, communications systems and laboratory instruments.
Current advanced femtosecond laser systems offer myriad possibilities to modify materials, from implementing new optical functionality to improving existing materials properties.
