A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the ...

The terahertz (THz) gap, a frequency band lying between the microwave and infrared regions of the electromagnetic spectrum where conventional technologies are inefficient in generating and detecting ...

CWRU is authorized to use radioactive material by the State of Ohio, which became an Agreement State on August 31, 1999. Radioactive material is extensively used in the several hundred biomedical ...

Scientists led by Strathclyde University have, for the first time, recreated a key property of outer space here on Earth. Using a special type of particle accelerator, the international team has ...

Eye injuries are of primary concern. The effect to the eye depends on various factors, including pupil size, pigmentation, laser pulse duration and repetition, and wavelength. Pierre Gougelman had the ...

The capability of synchrotron radiation to produce ultrabright emission has attracted considerable interest over the last half a century. To date, magnetic undulators with a period of several ...

Terahertz source: the work was done at the Laboratory for Laser Plasmas at Shanghai Jiao Tong University. (Courtesy: Laboratory for Laser Plasmas, Shanghai Jiao Tong University) Bright pulses of ...

Burns and other thermal effects are the predominant cause of laser radiation injury, either through direct contact or via accidental reflection. Some lasers are powerful enough that even a diffuse, or ...

COPENHAGEN — Low-level laser therapy (LLLT) ameliorated radiation dermatitis in a pilot trial conducted in 79 patients with breast cancer, known as the DERMIS trial. LLLT is a noninvasive modality ...

Despite decades of research and development into many aspects of radioactive materials, such as for power generation, defense and medical purposes much still remains unknown about radiation’s effects ...

The Laser Safety Program provides information on laser hazards and laser-related policies, procedures and recommendations for the safe use of lasers. Most of this information is based on the American ...
