SI Traceability of Force at the Nanonewton Level

January 1, 2001
Author(s)
David B. Newell, Jon R. Pratt, John A. Kramar, Douglas T. Smith, L Feeney, Edwin R. Williams
Although nanonewton force measurements are commonplace in industry, no National Measurement Institute supports a link to the International System of Units (SI) below one newton. The National Institute of Standards and Technology has launched a five-year

Single-frequency and Mode-locked Er/Yb Co-doped Waveguide Lasers

January 1, 2001
Author(s)
Berton Callicoatt, John B. Schlager, Kevin L. Silverman, Robert K. Hickernell, Richard P. Mirin, Norman A. Sanford, Joseph S. Hayden, Samuel D. Conzone, Robert D. Simpson
We present results for single-frequency and mode-locked Er/Yb co-doped waveguide lasers. The single-frequency DBR waveguide lasers have output power in excess of 80 mW with laser linewidth of 17 kHz. The passively mode-locked waveguide lasers produce

Small-Angle Neutron Scattering From Metal Ion-Containing PAMAMOS Dendrimer Networks

January 1, 2001
Author(s)
Robert A. Bubeck, Barry J. Bauer, P Dvornic, M J. Owen, S Reeves, P Parkham, L W. Hoffman
There is considerable interest in the development of nanocomposites based on dendrimers as host matrices. The intent is to take advantage of functionalized dendrimer interiors that can complex with an added constituent, resulting in nanocomposites for

Sources of Uncertainty in UV Radiation Measurements

January 1, 2001
Author(s)
Thomas C. Larason, Christopher L. Cromer
Increasing commercial, scientific, and technical applications involving ultraviolet (UV) radiation has led to the demand for improved understanding of the performance of instrumentaion used to measure this radiation. There has been an effort by
