Laser Etching Aluminum

Application Details:

Laser marking of aluminum was accomplished using a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The large and small tags were both surface etched to create a light white mark and engraved to create a deeper, darker mark on the samples. The etched tags were process using approximately 16 watts of power, with a frequency of 25kHz, and at a speed of 25 inches per second, resulting in cycle times of 2.28 seconds and 1.59 seconds for the large and small tags, respectively. The engraved tags were also processed at approximately 16 watts of power and a frequency of 25kHz, but at a speed of 5 inches per second, resulting in cycle times of 6.84 seconds and 4.65 seconds for the large and small tags, respectively. To create the raster and vector logos, the samples were surface etched using 15 watts of power, with a frequency of 25kHz, and at a speed of 25 inches per second. The cycle times for processing the marks were 8.87 seconds for the vector logo and 8.43 seconds for the raster logo.

Fiber Laser Marking Kit

The i-Series Fiber Laser Marking Kit was specifically designed for maintenance-free OEM applications.  It delivers a diffraction limited (M2<1.05) laser beam directly to the worksite via a metal sheathed single mode fiber cable.

These compact service-free lasers are designed to operate under high shock, vibration and dust conditions, with relatively high humidity and temperatures. They do not require routine replacement parts or materials. Wall-plug efficiencies up to 50% result in a compact size, reduced utilities, and trouble-free air cooling.

Fiber-to-fiber architecture means a robust, monolithic design with no optics to align or maintain, no mechanics to stabilize, and with the focusable power and high power densities needed for the most demanding applications. One cable connection makes it easy to integrate into any laser marking and engraving system.
