XRF-M Fiber Laser Series - NEW MODEL


The XRF-M is a Selectable Pulse Width (often referred to as a MOPA Fiber Laser). The XRF-M is part of the newest laser series that RMI offers. The lasers in this series mark 30% faster compared to previous generation lasers and are more reliable.

With power levels at 20, 30 and 60 Watts, the XRF-M Series Fiber Laser is a versatile laser marking system. The XRF MOPA fiber module is capable of marking on a wider range of materials than Fixed Pulse Width fiber lasers.

In the past, Fiber Lasers were favored for engraving metals and Diode Pump Solid State lasers were preferred for plastics. With 15 selectable pulse durations, the XRF-M is the best of both worlds. You can select longer pulses for the power to engrave metals and shorter pulses for sensitive plastics. The XRF-M can also create black, blue, green, red and other colors on steel.

Every XRF Series Laser is delivered with Symbol Writer Pro 2. The system supports multiple axis solutions. 3D engraving, serial and Ethernet communication. User configurable I/O make it easy to integrate with automation. Symbol Writer Pro 2 interfaces with text files, XLS spreadsheets and SQL databases.

XRF lasers are virtually maintenance free and are backed by RMI Laser’s industry leading warranty, and world class service and support.
