摘要： This disclosure provides a device for heating to generate a uniform molten pool, including: a source unit for generating an energy beam; a beam expanding/reducing unit positioned in an energy path of the energy beam for adjusting the diameter of the energy beam; a flat-top conical lens set positioned in the energy path and including at least two flat-top axicons, with the beam expanding/reducing unit positioned between the source unit and the flat-top conical lens set; and a focusing lens positioned in the energy path, with the flat-top conical lens set between the beam expanding/reducing unit and the focusing lens, and the energy beam being focused by the focusing lens. This disclosure generates a uniform molten pool to prevent vaporization splash due to overheating of the material during melting.

摘要： A laser processing device includes a laser emitter, an optical processor, a gas deflector and a gas source. The optical processor is furnished on optical path of the laser beam for guiding the laser beam to transmit along a looped processing path. The gas deflector has an optical channel, a looped gas channel and a looped gas outlet. The looped gas outlet is connected to the looped gas channel. The looped gas channel surrounds the optical channel, and a section of the looped gas channel close to the looped gas outlet is furnished in inclined position. The gas source is furnished on the gas deflector and is communicated with the looped gas channel for providing a gas flow to flow into the looped gas channel. The gas flow is guided by the looped gas channel.
