The crack propagation and surface formation mechanism of single crystalline diamond by a nanosecond pulsed laser
In this article, the surface formation mechanism of single crystalline diamond (SCD) by a nanosecond pulsed laser is performed, where surface cracking, phase transformation, and typical surface morphology are involved. The nanometric surface characteristics of the ablated micro-grooves on the diamon...
