The laser drilling process involves the use of an infrared laser (of surgical grade at a wavelength about 1064 nm) to bore very fine holes (less than 0.2 millimeters or 0.005 inches in diameter) into a diamond to create a route of access to a black carbon crystal inclusion.
Concrete is usually cut with water (wet cutting), for cutting concrete with adequate water can significantly reduce the dust, keep the diamond blade cool and extend its life, and improve the cutting efficiency (for wet cutting can be deep and continuous).
