Overview

Laser Radiometry Lab develops, improves and maintains national standards for characterization of lasers, along with detectors and other optical and optoelectronic components used with lasers and in laser-based systems. These standards support applications of lasers in manufacturing, electronics, medicine, communications and other fields. Additionally, they are used to disseminate national scales of laser radiometric in UV to IR wavelength and...

  • Measurement of Ultrashort Optical Pulses

    We made a set of spectral phase interferometer (SPIDER) for femtosecond optical pulses measurement. With this instrument, spectral phase can be measured and pulse waveform can be reconstructed using Fourier-transform technique.

International Cooperation

  • International comparison of laser power and energy between NIST and NIM.  2012~2013, in progress.
