Argus Laser News and Tips for using

To ensure stable laser output, the laser generator is usually fixed. To meet different processing needs, the laser beam’s transmission path is dynamically changed using optical elements like reflectors. This design, where the source is fixed but the reflectors and focusing lens move while maintaining stable output power, is called the “Flying Optics Path”.

How to Choose the Right Laser Cutting Machine for Acrylic, Argus Laser

In sheet metal fabrication, a common observation is that of two holes cut on the same plate, one can perfectly accommodate a flat head (countersunk) screw, allowing the screw head to sit flush with the material surface, while the other cannot, leaving the screw head protruding. The key to this issue lies in the "hole forming process" settings, especially for non-through holes requiring a countersunk effect. Here is a summary of the key technical points for achieving counterbores in laser cutting

This article explores the mathematical physics of thermal diffusion length (Lth = √4αt ), illustrating how transitioning from nanosecond to picosecond and femtosecond laser pulses compresses energy deposition time to virtually eliminate the Heat-Affected Zone (HAZ), recast layers, and micro-cracks in high-precision manufacturing.

This article explains the inverse coupling between ultrafast laser repetition frequency and single-pulse energy (Ep = Pavg / f), analyzing how frequency adjustments impact material removal rates (MRR), plasma shielding, and thermal accumulation to help engineers identify the optimal process window for high-efficiency, thermal-damage-free micro-fabrication.
