Industrial gas cylinder LASAL™ 4

helium

DESCRIPTION
LASAL™ is Air Liquide's brand dedicated to laser applications. LASAL™ 4 is a helium lasing gas intended for CO2 laser cavity generation and for welding and cutting laser processes. A CO2 laser with an integrated mixer uses lasing gases (N2, He, CO2); the purity of these gases is critical for source reliability, optical system lifetime, and stability and optimisation of delivered power.

Applications

• Laser cavity gas

Benefits offered by LASAL™ 4

• Productivity
  Supports optimisation of machine productivity, helps reduce operating and maintenance costs, and extends laser lifetime.
• Quality
  Formulated to ensure process safety and consistent laser performance.
• Expertise
  Technical support to define the most suitable gas according to material, application and laser source technology.

Supply modes
LASAL™ 4 (helium lasing gas) is available in individual cylinders and 9-cylinder bundles.
