The behavior of a He-Ne laser amplifier in the presence of an axial magnetic field has been studied experimentally by measuring Faraday rotation and gain for various values of input signal intensity. Two high-gain transitions in the 3.39-μ region were used for study-a J = 1 to J = 2 transition and a J = 1 to J = 1 transition. Theoretical expressions have been developed, which included the nonlinear effects of saturation strength signals. Experimental results clearly show saturation of Faraday rotation; in addition, for the J = 1 to J = 1 transition, a Faraday rotation reversal and a traveling-wave magnetic field dip are seen. These results match the theoretical predictions and provide a method for measuring the upper (3_s_2) level quadrupole moment decay rate.
