Ablation is the removal or destruction of something from an object by vaporization, abrasion, erosive processes, or other means. The object may be fully ablated away. Examples of ablation as it is rel

A controlled arc-flash, produced in a flashtube. Even though the energy level used is fairly low (85 joules), the low-impedance, low-inductance circuit produces a flash of 24,000,000 watts. With an arc temperature of 17,000 K (16,700 °C), the radiation output is centered at 170 nanometers, in the far UV. The intense burst of radiation easily penetrates the shade #10 welding filter which shields the camera.
