Abstract

In this work, we demonstrate an improved approach to power balancing the OMEGA Laser System that can target a 200-ps temporal feature in a given pulse shape. This optimization is achieved while maintaining the average power balance over the entire pulse shape. To accomplish this, a 60-beam power balance model of the OMEGA Laser System has been developed that uses measured losses and gains at each amplification stage on the system as inputs. The model is used to adjust the gain on the appropriate saturated amplifier to compensate for known losses on the system.
