Abstract
A common method of shaping laser beams into patterns for product marking and machining involves the use of masks. These masks result in inefficient use of the available laser energy, causing increased fabrication time and cost. Simple patterns, such as rings and tophat profiles can be easily formed with multi-aperture beam integrators, thus utilizing nearly 100% of the laser energy. This paper discusses multi-aperture beam integrators for forming a continuously variable ring pattern on the target plane. Both on-axis and off-axis systems are discussed.
