Abstract: Usually,a frequency stabilized He-Ne laser is used as a light source in an accurate measurements.This paper introduces a small frequency-stabilized He-Ne laser。The laser has small size,can be used in bad enviroment.To obtain long lifetime and better frequency stabilization,the structure of the laser is improved to increase cathod area,protect the has pollution,select the suitable materials and processing.
