摘　　要：研制成一种互锁的无调制的塞曼He-Ne激光稳频器。稳频中心调谐在左右旋光差频曲线的最大斜率点上,以获得有较大的激光输出功率,环路能给出快速锁定,秒级频率稳定度优于2×10^(-10)。A novel bias frequency-lock techniqne is proposed to stabilize a dual frequency Zeeman He-Ne laser. The servocontrol loop gives a rapid frequency control of a longlive laser tube. No audio modulation applied to the cavity of the laser and the output of desirable single frequency laser beam can be tuned in maxium. The short term frequency stabihzation is superior to 2×10^-10.
