Nowadays, the mainstream of far field beam smoothing technology adopted by foreign high power laser drivers is smoothing by spectral dispersion (SSD) based upon sinusoidal frequency modulation.
The critical factor causing the arc length fluctuation to affect the input heat power to the anode proves to be the phenomenon of the current dispersion in plasma arc itself.
