NIST extends laser power- and energy-meter calibration to ultraviolet wavelengths

Excimer-laser users requiring accurate, traceable laser power and energy measurements can take advantage of a new calibration service offered by the National Institute of Standards and Technology (NIST, Boulder, CO). Developed by NIST scientists Rodney W. Leonhardt and David J. Livigni, the system can calibrate power and energy meters for use with 248-nm krypton fluoride excimer-laser beams. The instrument consists of standard isoperibol calorimeters with a fused-silica beamsplitter. The divided

Developed by NIST scientists Rodney W. Leonhardt and David J. Livigni, the system can calibrate power and energy meters for use with 248-nm krypton fluoride excimer-laser beams. The instrument consists of standard isoperibol calorimeters with a fused-silica beamsplitter. The divided beam is sent to the meter under test and to the calorimeters, which provide the standard. The resulting calibration has an uncertainty of only 2%.
