633nm iodine steady frequency laser frequency evaluation system research

Abstract

This project has developed a 633nm iodine steady frequency laser frequency evaluation system. The overall structure is mainly composed of the national length of the 633nm iodine steady frequency laser, new laser, frequency shooting monitoring and technical unit, and frequent evaluation system. Through design experiments, respectively In the three major measurement technology indicators of the three major measurement technical indicators of the peak frequency difference, the stability of the laser frequency, and the duplication of laser frequency, the experimental result was not certainty of the wavelength of the new system of 2.9 × 10 -11 to meet the relevant technical indicators.
