- •
The damage induced by gamma rays to optical materials was highlighted and quantified, using laser techniques.
- •
Polarized light and the particularities of the laser light (monochromaticity, directionality and coherence) were used.
- •
The correlation between the damage and the gamma rays absorbed dose was made.
- •
The comparison between different types of optical materials and their dose related calibrations were made.
- •
The uncertainty associated to the technique was determined.
