I have a question in regards to sapphire and lasers. How does sapphire hold up against lasers. I need to cut some semi transparent film with a laser. I'm using a backlight and a machine vision system to determine where I need to cut, and then use a laser to cut. The focused laser power is less the 2 watts. Do you think sapphire would not ablate with this power of laser?
I think the laser illumination with power 2W has not to influence on sapphire surfaces or volume in region 0.3 - 5 microns wave length. Of course, it will be depend from quality of surfaces of sapphire.
