Abstract:Theoretical analysis of spectrum and frequency repetition of the double-model frequency stabilization He-Ne laser has been done, and the beat frequency experiment using 632 nm I2 frequency stabilization He-Ne laser has been carried out.The authors used the intercavity laser, and the double mode frequency stabilization to get the laser stabilized output through adjusting the two neighbor vertically polarized modes to the equal power reference point.Through the experiment, the authors analyzed the factors which affect the laser frequency repetition and stabilization, and measured the stabilized laser power and the frequency stabilization.The beat frequency experiment has shown that the frequency repetition can reach (1-2)×10-8 by frequency difference, and the laser stabilization can reach 10-10 by Allan variances.The experiments show that the stabilized laser can work well and can be used as frequency reference point.
