【摘要】 <正> 一、引 言 众所周知,兰姆凹陷稳频是以原子跃迁中心频率v₀为参考标准的;而纵向塞曼稳频是利用塞曼分裂的左、右旋圆偏振光的频率曲线的交点为稳定点的。因此,这两种稳频激光器内都必须充入²⁰Ne气体才能保证有单一的频率稳定点而实现高精度的稳频。而在横向塞曼稳频He—Ne激光器（以下简称为STZL）中,其稳频的参考点是由外加的参考更多还原

【Abstract】 In a 653 nm frequency-stabilized transverse Zeeman He-Ne laser(STZL),by the use of natural Ne instead of isotopic Ne,the intramode beat frequency taning curve is inverted V shape.The lock-in of intramode beat frequency is realized with a frequency stabilizer which can lock both frequency and phase and distingnish the slope sign of tunning curve.The frequency fluctuation achieved 5×10-11 over an integration perio drr.nge of 1-10 sec.This is almost as same as that of STZL filled with isotopic Ne(3×10-11) The advantage of this new method is to descrease the manufacture cost of STZL so that the necessary cocdiclion of with use of it has been provided.更多还原
