What is used to remove the material from a hole being drilled with a laser?
A) A jet of clean dry compressed air blasts the molten metal out of the hole.
B) Laser drilling is always done overhead so the molten metal will run out of the hole.
C) The intense heat vaporizes the spot with enough force to thrust the material out.
D) The laser is hot enough so that it passes through the molten metal until the hole is completed and then the molten metal drips out.

Question

The intense heat of the laser vaporizes the material, creating a vapor that expands rapidly and pushes the material out of the hole. This is known as "vaporization drilling." Option A is possible but not always the case, as some laser drilling processes may use different methods of removing debris. Option B is not accurate, as laser drilling can be done in any orientation. Option D is also not accurate, as the laser does not pass through the molten material but rather vaporizes it.
