Researchers have demonstrated that a strange type of quantum particle called the anyon, believed to exist in only two dimensions, can also be created in one
For more than three decades, the National Institute of Standards and Technology (NIST) has calibrated the wavelengths of lasers used in industry, academia, and
The purpose of this project is to develop and refine spectroscopic techniques based on nonlinear optics for the study of novel materials. Measurements that isolate the nonlinear response are often better able to uncover physical processes that, in the linear response, are subtle and hard to isolate
The design of the super-continuum solar simulator is shown below. Light is produced from 450 nm to 2400 nm in sub-nanosecond pulses at a repetition rate of 80 MHz. The total irradiance is sufficient to illuminate a 1 cm 2 cell at more than 1-sun. Initial tests have confirmed that solar cells respond
NIST has been a world leader in lasers since the technology's development in the early 1960s, a tradition continued when NIST scientist John L. Hall shared the 2005 Nobel Prize in physics for his part in the invention of the optical frequency comb. The output of a comb is a brief broadband pulse
Over the past several years, we have focused on bolometric detection of THz radiation. Our initial work on cryogenic detectors has been extended to antenna-coupled bolometers operating at room temperature. These detectors provide a rugged, low-cost alternative for homeland security applications; e.g
