Detailed Description
The short video is of a post laser ablation crater using a nanosecond 193nm laser ablation system of a glass slide using a 210 micron spot diameter and 250 shots. It shows a flat bottom crater indicative of a homogenized laser beam, though the measured diameter of the crater appears to be 25 microns smaller the diameter set. The 3D crater image was created using a Keyence 3D digital microscope.
