The parts were marked using a 20-watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The samples were etched with the information provided by the customer.
154
The plastic door handlers were marked using a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The working distance from the bottom of the lens housing to the painting surface was set at 180 mm (including 5 mm focal offset).
188
Stainless steel parts were marked with a 20-watt q-switched fiber laser with a 160 mm focal length lens. The parts were deep engraved using 18 watts of power, a frequency of 20 kHz, and a speed of 5″ per second. The stamp marks on the samples the customer sent were duplicated. The total cycle time was 131 seconds.

This bone screw sample was marked with a 10-watt q-switched ytterbium fiber laser and a 160 mm focal length lens. The 160mm focal length lens has a working distance of 176mm from lens to part. The part was surface marked to create contrast on the sample. This titanium piece was marked with a cycle time of 9.36 seconds. This sample had a cycle time of 0.53 seconds per mark with a total of 6 marks on the sample.

Laser marking was done with three different parts which were all marked with the 20-watt q-switched ytterbium fiber laser. The parameters used varied slightly from part to part. The parts were marked with a bold Arial font, with the exception of the markings on the smallest screw head. The parts were marked with a very light etch to produce the best contrast. The small 0.370” diameter screw head had a cycle time of 0.497 seconds. The larger 0.78” diameter screw head had a cycle time of 1.89 seconds and the black-coated 0.960 diameter washer had a cycle time of 2.53 seconds.

The samples were marked with a 20 watt q-switched ytterbium fiber laser with 160 mm focal length lens. The paint film was ablated using 18 watts of power, frequency of 30 kHz. Due to the fact that the tallest marking would be in the 3 to 4 inch range, the 160-mm focal length lens with 4.3” x 4.3” marking field was used in the application. The longer focal length lens was recommended to be used for marking larger area. The paint film on the largest trunk finisher looked thicker than that on other parts so that more passes of lasing were applied.
189
The parts were marked with a 10-watt q-switched ytterbium fiber laser marking system with a 160 mm focal length lens. The parts were surface etched, to create a contrasting mark. The sample parts with the serial number 3417210 resulted in a cycle time of 1.74 seconds. The parts were marked at 25 inches per second using approximately 8 watts of power with a frequency of 25 kHz.
107
The parts were laser marked using a 20-watt q-switched ytterbium fiber laser with a 160mm focal length lens. The parts were surface marked to create brightly contrasting marks. The parts were marked using various parameters, resulting in various cycle times, gradients, and mark quality on the sample.

This ceramic medical part was laser marked using a 20 Watt Fiber Laser Marking System.
156
The plastic door handlers and trunk finishers were marked with a 20-watt q-switched ytterbium fiber laser with a 160 mm focal length lens. The paint film was ablated using 18 watts of power, a frequency of 30 kHz. The paint film on the largest trunk finisher looked thicker than that on other parts so that more passes of lasing were applied.
190
The parts were marked with a 10-watt q-switched ytterbium fiber laser marking system and a 160 mm focal length lens. The parts were surface etched, to create a contrasting mark. The parts were marked with two different serial numbers, each with its own cycle time. The samples with the serial number 4088605 resulted in a cycle time of 1.82 seconds. The parts were marked at 25 inches per second using approximately 8 watts of power with a frequency of 25 kHz.
