Highly stable iodine stabilized frequency helium neon laser

Reference source for iodine stabilized frequency system, primary stabilized frequency helium neon laser

The NEO-92SI-NF launched is a small-sized portable iodine stabilized He Ne laser on the market. Developed by the National Institute of Metrology (NMIJ) and the National Institute of Industrial Technology (AIST) in Japan, it meets all the requirements of the 1992 and 1997 agreements and licenses of the Committee on Metrology (CIPM). NEO-92SI-NF serves as a reference source for iodine frequency stabilization systems and is a primary frequency stabilization laser that stabilizes the wavelength of He Ne lasers to the iodine absorption peak through iodine absorption.
