Mechanism study of deep self-modulation in He-Cd laser
In this paper, the mechanism of deep self-modulation 4416 A output in He-Cd laser at ion-wave characteristic frequency is roughly discussed. The output of self-modulation is produced through penning collision because the moving striation causes the fluctuation of metastable He atom density. Deep modulation means strong initial disturbance at the positive column near the anode, but there is no considerable amplification factor along the tube axis.
