Keyhole-structure and Stability in Laser-beam Penetration Into an Absorbing Liquid (Water)
레이저 빔의 흡수 액체 내 침투에 의해 생성된 키홀 구조와 안정성
Abstract
When a high-power laser beam is irradiated on the surface of material, it is well known that a cavity, called a keyhole induced by the pressure action of the vapor plume, is generated in the molten material. This paper describes the interaction between a pulsed CO
