Microcombs – chip-scale devices that generate and measure frequencies of light with exquisite accuracy – have transformed timekeeping and boosted optical
When NIST scientist Tasshi Dennis first encountered quantum physics as a student, he was skeptical it would ever amount to any practical applications. Little
Far-infrared (or terahertz/THz, ca. 25 to 300 micron wavelength) femtosecond pulsed laser and Fourier-transform infrared methods are employed to measure
PRIME (Platform for Realizing Integrated Molecule Experiments) aims to establish primary, quantum-based realizations for both the radiometric watt and kelvin
The small mass and force metrology project at NIST leverages the redefinition of the International System of Units (SI) to scale mass and force with electrical
The NIST Mass and Force Group disseminates the unit of mass, the kilogram, to the US measurement system through calibrations of customer weights and weight sets
