A high-throughput laser micro-machining platform has been developed using a programmable multi-spot modulated line beam capable of more than 30 times throughput-enhancement over a single-spot system.
While commercially available lasers have been rapidly expanding in energy and power, single-spot scanning systems cannot take full advantage of these advancements. The system provides high throughput and high-resolution micro-processing on a variety of surfaces (stainless steel, aluminum, and polymer).
This high productivity system is enabled by a high-power MEMS spatial light modulator called the Linear Planar Light Valve (Linear ™). The Linear PLV™ is a 1088-pixel device in a linear configuration capable of greater than 100 kHz 10-bit amplitude modulation. The Linear PLV™ supports pulse energies of ~1 mJ (1064 nm, 10 ps) and has been used at pulse widths down to 300 femtoseconds.
The Linear GLV® laser marking systems can resolve features as small as 10 µm with an edge placement resolution of 2.5 µm. Large area processing is done by scanning and stitching this line beam across the media using X-Y stages and a unique relay galvo scanner has been incorporated into the system to allow for faster scanning over a 15 x 15 mm area.
Katana EX provides customers with the flexibility of having a laser external to the Katana system. This opens the door to new possibilities with larger, higher power laser systems, or laser vendors preferred by the customer.
