RMI Laser Offers New 20-Watt DPSS Laser Marking System
Laser marking system.
Lafayette, CO — RMI Laser has introduced the U-20, a 20-watt, Q-switched Laser Marking System for high volume throughput. It is suitable for large batches when marking areas range from 4 to 12-in.2 The U-20 can be used on all metals, most plastics, composites, ceramics, and a wide variety of other material substrates.

The U-20 has a built-in, diode-pumped ND: YVO4 laser source, which provides nearly twice the peak power of the company's previous marking system (from 120kW to 200kW), while maintaining superior beam quality.

The innovative system performs fast engraving from 0.001 to 0.004-in. and vector marking at very high speeds, making it especially suitable for marking-on-the-fly (MOTF). Due to the very short pulse duration (<10 nanoseconds), the heat level is kept to a minimum during operation, making the U-20 well-suited for heat-sensitive materials or processes.

The extended focal plane depth enables the laser to mark around curves or on curved surfaces without distortion or degradation; it also provides higher/darker contrast in much less time. The unit is excellent for cutting thin metals and for surface laser markings on extremely durable metals like titanium or tool steel, and/or on austenitic super alloys such as Inconel®.

Included in the standard system are the marker head, controller, laptop computer, focusing diode, 163mm F-Theta lens, Z-axis lab jack, mounting stand, laser safety goggles, and the company's proprietary SymbolWriter-Pro software.
