Abstract
A kind of defects on the incident surfaces of fused silica optics are reported having the potential to initiate the damages on the exit surfaces in the final optical assembly in high power lasers. In this light, the new safe criterions for defects on the incident surfaces are proposed to avoid the detrimental modulation effects in downstream.
