"The 'Death Spiral' of Laser Lens Contamination: How Dust and Oil Weaken Laser Damage Thresholds" In laser processing equipment, laser lenses, mirrors, and protective optics serve as the optical path's "eyes." These laser lenses feature highly precise reflective or anti-reflective coatings. They skillfully guide and focus high-energy density laser beams....
The Cold Art of Glass and Ceramics How UV Lasers Enable Crack-Free Processing
In modern manufacturing, brittle materials like glass, sapphire, and alumina ceramics are both highly valued and challenging. These materials offer exceptional hardness, wear resistance, and insulation. Consequently, they are essential for smartphone screens, semiconductor substrates, and high-end optical components. However, they are also notoriously delicate. Slight processing errors can cause...
The Art of Laser Pulsing Understanding RF Laser Pulse Width and Repetition Rate
In industrial micromachining, people often call the laser a "light knife." Unlike a common metal tool, this "light knife" cuts continuously. Furthermore, it can "flash rapidly" thousands of times per second. This flexible switching between continuous wave (CW) and high-frequency pulsed modes is a captivating physical characteristic of RF (Radio...
