Paper Abstract

A new method for the design of reverse saturable absorbing (RSA) dye concentration gradient (CG) limiters is developed and applied to produce three new designs. The radiation transport equation and the divergence behavior cI Gaussian beams are solved together analyticaly for the dye concentration gradient and the fluence distribution in the sample. It is demonstrated that the fluence distribution for a given CG can be found which is independent of the dye kinetics. A new figure ofmerit for gradient RSA limiters is defmed and used to compare designs. These new designs are shown to be significantly better than a constant fluence design. These designs are useful for initiating numerical nonlinear beam propagation studies.
