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 a vector graphic format. If in raster, they should be in a higher resolution to get a cleaner mark.
