e laser damage anisotropy is thus generated by the anisotropy of the SRS threshold.
is tentative model also explains that the laser damage anisotropy is only observed at
certain irradiation conditions, those where the z-polarized SRS threshold is lower than
the damage threshold.
For LBO, available data on the properties of the color centers and their interaction
with phonons are less detailed, but the similarity of the laser damage observations and
the types of color centers may indicate an analogous explanation of the polarization-
dependent laser damage anisotropy in this material.
