What You Must Know About Single Mode Fiber Laser Markers

Figure 1.  Single mode and multi mode laser intensity and beam diameter. Single mode lasers have the best beam quality laser, with M2 values around 1.1-1.2.  Lasers with M2 values above this are considered multi mode (higher order). The fiber laser naturally produces a high quality beam, so on paper the differences may appear small, but they are huge in processing terms.
The single mode fiber laser marker has best-in-class beam quality that translates to fine marking capabilities plus effective micromachining for drilling, cutting, scribing, ablation for a variety of applications.

5-Axis Laser Cuts Costs at Kryton

The horizontal rotary table on the Rofin UW505 2,000 Watt 5-Axis Fiber Laser Work Station at Kryton facilitates easy mounting and centering of part fixtures in the workstation. Rotating the part to locate hole cutting positions or to perform flange cuts greatly enhances the efficiency and accuracy of the system. The vertical rotary drive of the laser cutting head represents the 5th axis and allows the cutting head to maintain perpendicularity of the laser beam to the material’s surface.
This technical review examines how 5-axis laser processing dramatically improved the secondary processing of 3D parts at this high tech job shop.

Etching Out New Advantages with Existing Laser Cutting Systems

Deep etching is very common with parts that are powder coated or tumbled. A deeper etch ensures the part number or other identifying information remains readable downstream. This can be achieved by moving the nozzle standoff closer to the part. The lower the focus of the beam, the deeper the etch into the material. (first view)
Here are some ways to take full advantage of your laser cutting machines etching ability, from decorative purposes to part numbers.

Micromachining of Metals Cheaper, Faster with New Laser Technology

Advanced Cutting Technology

The new fiber head on the 5 kW Platino Fiber from Prima Power uses a single universal lens for all materials, eliminating the need to change lenses resulting in near-zero setup time. Furthermore, the optical chain is completely sealed to eliminate any possibility of contamination. The fiber head features a 35 mm stroke on the focal axis, a dedicated lens drawer with Optical Precision Control quick alignment technology, and exchangeable protective glass that allows easy inspection to keep the optics safe and reliable.
The 5 kW Platino Fiber laser from Prima Power delivers piercing time reductions of up to 90 percent, near-zero lens setup times and cutting speeds of up to 5 m/min on stainless steel.

Sapphire Fiber Laser Windows Provide 1/4 Wave Transmitted Wavefront

Highly polished Sapphire Fiber Laser Windows from Laser Research Optics are ideal for use as debris shields on 1064 nm industrial fiber cutting lasers from 4 kW and above. Providing 1/4 wave transmitted wave-front, they feature Moh 9 hardness, which is second only to diamond. They also feature a 10-5 scratch-dig finish and can withstand steel splatter, flash, and debris.
These sapphire cover glass windows for 4 kW and larger industrial cutting lasers prevent contamination of the fiber lens from debris and feature Moh 9 hardness that is second only to diamond.
