LASAL™ Gases

Laser cutting and welding to improve productivity and lower operating costs

The choice of your lasing gas or assist gas will determine the reliability of your laser, the lifespan of your optics and output power. Air Liquide pioneered the laser industry standard for effective, consistent control of impurities. We supply a full range of lasing gases with the industry’s highest purity standards for every laser resonator.

Whether your application requires nitrogen, carbon dioxide or helium, our LASAL gases and multi-component mixtures help lower operating costs by substantially increasing speed and quality, and extending the lifetime of the laser.

LASAL lasing gases – carbon dioxide, nitrogen and helium – can be supplied separately or premixed, depending on the laser source used. Air Liquide has defined lasing gases for each type of laser source according to laser manufacturer specifications.
