Description
Adjustable Mode Laser
In sintering and welding spots of different sizes are often processed in sequence. Solutions for changing beam spot size requiring external moving bulk optics, such as zoom collimators, are slow, expensive, result in energy losses and are prone to optics contamination. The YLR-AM laser allows user to rapidly change beam spot size from single-mode to ~2x larger in diameter from the same laser without any bulk moving external optics. Multi-mode output is a round flat-top spot. Single-mode and multi-mode outputs are controlled independently, operating sequentially or superimposed in any time-dependent fashion. The YLR-AM laser offers user ability to switch between two spot sizes while maintaining approximately constant fluence.
