Laser cutting equipment requires concrete gas mixtures to create the laser beam. At the Greco Gas laboratory in Tarentum, we produce gravimetric mixtures of Argon, Helium, CO2, and CO (Carbon Monoxide) in many combinations. Our component gases are UHP (Ultra High Purity) grade, producing superior beam quality.
Yes, the unique dry process of the OZPEN™ can remove very small particles (< 100 nm in size) without the need for using other wet cleaning techniques. However, embedded debris must be removed using other techniques.

The OZPEN™ generates and propels an adjustable spray of clean dry air or nitrogen containing small CO2 particles to efficiently remove foreign matter from a surface. It delivers a precisely controlled accelerated stream of solid carbon dioxide particles (i.e. snow) at high velocity. The snow is created from the conversion of liquid CO2 to solid CO2 particles and CO2 gas at the spray nozzle.
Let's discuss how lasers work because this is some cool science! Gas lasers are made by passing an electric current through one of several certain noble gases or gas mixtures. The electricity excites the electrons within the gas's atoms and elevates them to highly energized orbits around their atoms' nucleus. When the electrons return to their normal, lower energy state, the electrons will emit particles of light called photons.
What's neat about photons is that the light they emit is a consistent wavelength dependent on the amount of energy that was released. Since all the energy is of the same wavelength, only one color in the color spectrum will be emitted. Emitting variations in wavelength produces natural light, but a uniform wavelength will create a single color, such as red or blue. The other distinct factor about laser light is, it is directional, making a beam of consistent light that doesn't diffuse; lasers can keep a focused beam for miles, a characteristic termed as "coherent."
This efficient and effective process removes various residues, including dust particles, polishing compounds, fingerprints, and surface films, from critical substrate surfaces. The OZPEN™ is superior to solvent cleaning wiping techniques and offers a quick dry and solvent-free cleaning process.

Gas laserworking principle
It's easy to remember how laser beams work when you think about the acronym -- "Light Amplification by Stimulated Emission of Radiation." Here at Greco Gas, we talk about gas lasers, but lasers can also be made by passing the electricity through glass or crystals. They are instrumental in consumer electronics like CD and DVD players, measuring, munitions, computing and surgery.

There are several basic ways that laser gas can be supplied. Individual cylinders are a safe, easy and economical way of providing gas to the laser machine. One thing to keep in mind is that there can be an interruption in gas flow when changing the cylinders or cluster of cylinders.

Another supply option is a cylinder bank system. This method is recommended for wall mounting and uninterrupted operation. The benefit of this is that the switchover is performed manually or automatically.
