What Is Excimer Laser Gas? A Complete Guide to Excimer Laser Gas Mixtures

Excimer laser gas is a specialized gas mixture used as the active medium in excimer laser systems. Unlike conventional industrial gases, excimer laser gases require precise composition, controlled purity, and stable performance to support consistent laser output.

Newradar Gas specializes in supplying excimer laser gas mixtures and specialty laser gas solutions for applications requiring high-purity gas products.

How Does Excimer Laser Gas Work?

Excimer lasers generate ultraviolet laser light through a mixture of rare gases and halogen gases.

Typical excimer laser gas mixtures include:

• Argon (Ar)
• Krypton (Kr)
• Xenon (Xe)
• Fluorine (F₂)
• Hydrogen Chloride (HCl)
• Neon (Ne)
• Helium (He)

The gas composition determines the laser wavelength and application.
