Broad Spectrum Capabilities for CW Laser Power Measurements at NIST

May 1, 2005
Author(s)
Joshua A. Hadler
Recent improvements for mid-level laser power measurements (1 μW to 1 W) have increased the range of calibrations available to customers of our CW laser power measurements. In this presentation we present an overview of our capabilities as well as recent

Intramural comparison of NIST laser and optical fiber power calibrations

March 1, 2004
Author(s)
John H. Lehman, Igor Vayshenker, David J. Livigni, Joshua A. Hadler
The responsivity of two optical detectors was determined by the method of direct substitution in four different NIST measurement facilities. The measurements were intended to demonstrate the determination of absolute responsivity as provided by NIST

New and Future Capabilities for CW Laser Power Measurements at NIST

January 1, 2003
Author(s)
Joshua A. Hadler
The CW Laser Radiometry project in the Optoelectronics Division at NIST is concerned with measuring steady-state laser, detector, and component properties such as laser power and energy, laser beam profile, detector spatial and angular responsivity
