Previously we found 5% loss on single pass measurement ( of laser power), new crystal was used to build a new SHG.

Saw a spot on the corner while the crystal was still mounted on the block, but it is hard to judge if it is a defect or reflection.

Remove the crystal from the block, some indium was stuck in the middle of the crystal.

Found some cracks and chip in the middle section of the crystal under the microscope.
