Process: Laser Annealing
Detailed Application View
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.
Recommended Laser Systems: Fiber Laser Engraving Machine
Fiber Tower™ Series is the new generation of Fiber Laser Material Processing Systems for Direct Parts Marking, UID Marking (Unique Identifier), and Deep Engraving. It is the most advanced, compact, industrial grade, mid size, Fiber Laser Engraving Machine available on the market. Fiber Tower™ series employs the new generation of solid state Ytterbium fiber laser systems of near infrared spectral range (1060-1080nm) with a unique combination of high peak power, ideal beam quality, fiber delivery and highest electro-optical wall-plug efficiency
These laser machines possess a reliability that is unmatched by any other kind of solid state or gas laser systems. Wide selectivity of operating wavelengths, ultra-low amplitude noise, high stability and ultra-long pump diode lifetime complete an impressive list of advantages of these modern fiber laser systems. 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.
