Plasma guides maintain focus of lasers

In science fiction, firing powerful lasers looks easy—the Death Star can just send destructive power hurtling through space as a tight beam. But in reality, once a powerful laser has been fired, care must be taken to ensure ...

A sound boost to extreme laser performance

Diamond is a particularly interesting material for this type of laser for two key reasons. Its high thermal conductivity means it is possible to make miniature lasers that simultaneously have high stability and high power. ...

On-chip light source produces versatile range of wavelengths

Researchers have designed a new chip-integrated light source that can transform infrared wavelengths into visible wavelengths, which have been difficult to produce with technology based on silicon chips. This flexible approach ...

SLAC fires up electron gun for LCLS-II X-ray laser upgrade

Crews at the Department of Energy's SLAC National Accelerator Laboratory have powered up a new electron gun, a key component of the lab's upgrade of its Linac Coherent Light Source (LCLS) X-ray laser, and last night it fired ...

Nature-inspired antibacterial metals

From aviation to medicine, various sectors are increasingly using materials that mimic the lotus plant, whose leaves have self-cleaning properties. Thanks to the bumpy surface structure covered with tube-shaped wax crystals, ...

Researchers develop first supersymmetric laser array

A team of University of Central Florida researchers has overcome a long-standing problem in laser science, and the findings could have applications in surgery, drilling and 3-D laser mapping.
