The goal of this project is to extend and improve the measurements of the key climate record of the long-term balance between Earth absorption of solar energy
The goal of this project is to utilize NIST expertise in privacy, cybersecurity, machine learning, wireless technology, ranging, modeling, and hardware and
We seek to make the most accurate measurements of kilowatt-class (CW) lasers and are using radiation pressure to do so. Currently, the most accurate laser power
High-power continuous wave lasers have output powers from tens of watts to hundreds of kilowatts. Their applications are anywhere localized delivery of high
The NIST Laser Power and Energy Calibration Project develops and maintains the U.S. national standards for the characterization of laser power and energy
Laser-based manufacturing processes such as laser welding and laser powder bed fusion (metal additive manufacturing) depend critically on the absorption of
In laser powder bed fusion (LPBF) additive manufacturing the laser power levels are typically from 50 W to 1 kW. Power measurements in this range are typically
Accurate characterization of photonic equipment is important for optical communications, medical devices, semiconductor lithography, manufacturing and materials
The goal of this project is to develop single photon source and detector measurement and calibration capabilities to support the emerging quantum industry and
Imaging in the terahertz frequency range enables the detection of concealed weapons and other contraband (e.g., explosives under clothing) without the use of
Machine learning and artificial intelligence (AI) have advanced so rapidly that they can now outperform humans at many (or even most) tasks. However, the large
