A breakthrough in developing multi-watt terahertz lasers

Terahertz lasers could soon have their moment. Emitting radiation that sits somewhere between microwaves and infrared light along the electromagnetic spectrum, terahertz lasers have been the focus of intense study due to ...

Laser-powered rover to explore moon's dark shadows

A laser light shone through the dark could power robotic exploration of the most tantalizing locations in our solar system: the permanently-shadowed craters around the moon's poles, believed to be rich in water ice and other ...

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 ...
