Latest Far-infrared laser Stories
University of Leeds researchers have taken the lead in the race to build the world’s most powerful terahertz laser chip.
Whether it is diagnostic imaging, analysis of unknown substances or ultrafast communication – terahertz radiation sources are becoming more and more important. At the Vienna University of Technology, an important breakthrough has been achieved.
Dr. Roberto Morandotti and his team at the INRS Énergie Matériaux Télécommunications Research Centre have developed a device that is critical to the use of terahertz (THz) sources for a variety of applications.
Researchers at Northwestern University have developed a simpler way to generate single-chip terahertz radiation, a discovery that could soon allow for more rapid security screening, border protection, high sensitivity biological/chemical analysis, agricultural inspection, and astronomical applications.
Terahertz radiation can penetrate numerous materialsâ€”plastic, clothing, paper and some biological tissuesâ€”making it an attractive candidate for applications such as concealed weapons detection, package inspection and imaging skin tumors.
Advance in metamaterials leads to a new semiconductor laser suitable for security screening, chemical sensing and astronomy.
MIT researchers have developed a new way to tune the frequency of lasers that operate in the terahertz spectrum - an important step toward airport scanners that could tell whether a vial in a closed suitcase contains aspirin, methamphetamines or an explosive.
Northwestern University researchers have achieved a breakthrough in quantum cascade laser output power, delivering 120 watts from a single device at room temperature.
Coherent Inc, a world leader in laser technology with headquarters in the USA, and the PTB have joined their expertise in Terahertz technology.
The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings.
