Abstract

We show that electrostriction can dominate the nonlinear refraction in CS/sub 2/ for nanosecond pulses. We use this effect in a new cascaded limiter geometry to make an extremely high performance optical limiter. We adopt an approach that uses two quite different nonlinear processes in separate focal planes. In one focal plane, we place a reverse saturable absorber (RSA) material. To protect this, we place a cell of CS/sub 2/ in another focal plane. Due to the strong electrostriction in CS/sub 2/ for ns pulses, the limiter performs well.
