“…In our previous work, 1,2 we reported the results of international comparisons of reference standards used in the calibration of optical powermeters. Those reports describe the results that were obtained by use of open laser beams 1 and optical fiber cable 2 at 1302 and 1546 nm.…”

We describe the results of a comparison of reference standards between three National Metrology Institutes: the National Institute of Standards and Technology (NIST, USA), the National Metrology Institute of Japan/National Institute of Advanced Industrial Science and Technology (NMIJ/AIST, Japan), and the Federal Office of Metrology (METAS, Switzerland). Open-beam- (free field) and optical-fiber-based measurements at wavelengths of 1302 and 1546 nm are reported. Three laboratories' reference standards are compared by means of two temperature-controlled, optical trap detectors. Measurement results show the largest differences of less than 4.2 parts in 10(3), which is within the expanded (k=2) uncertainty for the laboratories' reference standards.

“…Their performance is primarily limited by inequivalence between electrical and optical heating, due to factors such as radiative and convective cooling of the optical receiver, and its limited diffusivity, which results in the formation of temperature gradients, and parasitic heating in the electrical heater leads [24]. Best performance can be achieved using calibrated cryogenic radiometers operating near liquid helium temperatures, which usually serve as the primary standards [25] and which nowadays provide uncertainties of less than a few parts in 10 4 . Non-cryogenic, portable power, and energy transfer standards hardly achieve accuracies below 1% [25][26][27].…”

Energy calibration of integrated path differential absorption lidars

The stringent requirements for energy reference measurement represent a challenging task for integrated path differential absorption lidars to measure greenhouse gas columns from satellite or aircraft. The coherence of the lidar transmitter gives rise to speckle effects that have to be considered for accurate monitoring of the energy ratio of outgoing on-and off-line pulses. Detailed investigations have been performed on various measurement concepts potentially suited for deployment within future satellite missions.

“…More than one type of detector or standard may be employed as a transfer standard for any given measurement. NIST Standards currently in use for this service include the C-Series Laser Calorimeters [4,6,7,8], and NIST Standard Diode Trap Detectors [9,10,11,12,13,14,15]. Historically, calibration services for laser power and energy meters have been provided by use of calorimeters that were electrically calibrated and directly traceable to SI units through electrical standards.…”

Congress to "assist industry in the development of technology ... needed to improve product quality, to modernize manufacturing processes, to ensure product reliability ... and to facilitate rapid commercialization ... of products based on new scientific discoveries." NIST, originally founded as the National Bureau of Standards in 1901, works to strengthen U.S. industry's competitiveness; advance science and engineering; and improve public health, safety, and the environment. One of the agency's basic functions is to develop, maintain, and retain custody of the national standards of measurement, and provide the means and methods for comparing standards used in science, engineering, manufacturing, commerce, industry, and education with the standards adopted or recognized by the Federal Government. As an agency of the U.S. Commerce Department's Technology Administration, NIST conducts basic and applied research in the physical sciences and engineering, and develops measurement techniques, test methods, standards, and related services. The Institute does generic and precompetitive work on new and advanced technologies. NIST's research facilities are located at Gaithersburg, MD 20899, and at Boulder, CO 80303. Major technical operating units and their principal activities are listed below.
