The article discusses the methods of laser drilling. These methods include percussion drilling, mechanical trepanning, and optical trepanning. The percussion drilling uses pulsed lasers with laser spot approximately equal to the diameter of the hole while the mechanical trepanning utilizes tiny laser spot with diameter much smaller than the diameter of the hole. On the other hand, optical trepanning, uses stationary annular beam.
