文摘
- •
A polarization dependent damage performance anisotropy in type I doubler KDP crystals was investigated.
- •
The measured pinpoints density as a function of the fluence is wavelength and polarization dependent.
- •
Neither fluence nor polarization has impact on the size distribution of pinpoints.
- •
Different categories of precursor and different mechanisms responsible for damage initiation exist in doubler KDP crystals.
