What Are Excimer Laser Gas Mixtures?

Excimer laser gas mixtures are precision-engineered blends of noble gases (krypton, argon, xenon) and reactive halogens (fluorine, chlorine) that generate high-energy ultraviolet (UV) light when electrically stimulated. These specialized formulations are critical for applications requiring nanoscale precision, from microchip fabrication to vision correction surgery.

Core Components:

• Active Gases: Kr (Krypton), Ar (Argon), Xe (Xenon)
• Halogen Sources: F₂ (Fluorine), Cl₂ (Chlorine)
• Buffer Gases: Ne (Neon, 90-99% base) for optimal energy transfer
