OPTICAL LIMITING IN SEMICONDUCTOR-DOPED GLASSES

We report optical limiting at 527 nm in two Schott semiconductor-doped glasses OG530 and OG515. These two glasses show quite contrasting non linear optical behaviour. The glass OG515 shows strong clamping while OG530 shows no clamping in optical limiting inspite of having much lar ger nonlinear refractive index. Similarly OG530 exhibits saturation of absorption while OG515 does not.
