Abstract

We have modeled the output of a feedback stabilized regenerative amplifier (regen). We solve the rate equations including upper- and lower-laser-level lifetimes explicitly. The complete regen dynamics including the losses due to the feedback stabilizer are modeled. We provide a prescription for determining the injection-pulse shape required to produce a given output-pulse shape from this region. The model shows excellent agreement to measured regen output. This model of the regen along with our code RAINBOW, completely describes the temporal dynamics of the OMEGA laser system allowing OMEGA users to specify on-target pulse shapes in advance.
