Researchers led by Qing Hu and Zbig Wasilewski have now partially overcome this barrier by developing a QCL that produces light in the THz region with only a modicum of cooling. At 250 K, the new ...

A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning ...

Tunable terahertz wire laser Date: May 13, 2010 Source: Optical Society of America Summary: Terahertz (THz) radiation is one of the hottest areas of modern physics research.

A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning ...

Tiny terahertz laser could be used for imaging, chemical detection New design boosts the power output of the best-performing chip-scale terahertz laser by 80 percent.

"My group has been working on the generation of THz radiation by laser-induced filaments in air for almost 20 years," Aurélien Houard, senior author of the paper, told Phys.org.

A room-temperature semiconductor terahertz laser is portable, and since it can be fabricated in bulk on a wafer, it would be more economical than other types of terahertz lasers.

“Our laser opens up this spectral region, and in my opinion, will have revolutionary impact.” The team has now described the theoretical proof and demonstration of this widely tunable and compact ...

Terahertz generation benefits from laser know-how. 21 Jun 2007. Although many applications could potentially benefit from terahertz radiation, finding a convenient way to generate it has been ...

Sandia National Laboratory reports that its Terahertz Microelectronics Transceiver Grand Challenge is on track to enable a portable device that harnesses what it claims to be the world's first ...

Engineers from Harvard, MIT, and the US Army created this experimental terahertz laser setup in 2019. They are among the few to do so. Arman Amirzhan, Harvard SEAS ...

PORTLAND, Ore. &#151 What's claimed to be the world's first room-temperature terahertz laser harnesses the optical equivalent of heterodyning to bridge the terahertz gap. Today, a terahertz-gap exists ...
