PROGRESS IN DUAL FREQUENCY HeNe LASER AND APPLICATION

S. Zhang, Y. Li, X. Zong
Abstract:
Recent important progress in Dual frequency He-Ne lasers is reported, including two methods and experimental results to avoid mode competition and generate the frequency difference covering of 1~40 MHz, and the principle and the experiments of making a birefringence dual frequency laser itself be a displacement sensor with l/8 resolution, 8mm measurement range, and the function of selfcalibration.
