The samples were marked using a 20 watt Q-switched Fiber Laser using a 160 mm lens. The Colt logo (vector graphic) was annealed using 15 Watts of power, frequency of 80 kHz, speed of 5" per second, resulting in a cycle time of 8.65 seconds. The FBI logo (raster graphic) was annealed using 15 Watts of power, frequency of 35 kHz, speed of 5" per second, resulting in a cycle time of 9.43 seconds. The JTTF logos (raster graphic) were etched using 9 Watts of power, frequency of 35 kHz, speed of 20" per second, resulting in a cycle time of 11.14 seconds for the inside box and 4.76 seconds for the no box image. These images would have been crisper if they had been in vector graphic. If in raster, they should be in a higher resolution to get a cleaner mark.
