The optical damage threshold of ?-BaB2O4, ?-BaB2O4, LiB4O7 and CsLiB6O10
was experimentally studied. It was observed that the damage dimensions
in studied crystals linearly depend on the laser irradiation intensity.
The resistance against laser irradiation is highest in LTB crystals and
decreases through BBO crystals to ABO crystals and is lowest in CLBO crystals.
The appearance of optical anisotropy under powerful light illumination
was observed at the power density of two orders smaller than damage threshold.
At the powerful beam propagation along the optical axis of studied crystals
the observed shape of damages possess the view of stars with the rays parallel
to the symmetry elements of the crystals.
Key words: optical damage, borate crystals.
