LASER APPLICATIONS

Laser Application

Nitrogen has many uses in laser applications. As a purge gas to prevent oxidization, to blanket  delicate materials or expel fumes, nitrogen is the choice in a wide array of industrial and even medical environments, including:  

 

Laser Beam Path Purge -- In metal working, contamination in the beam path of a laser is a major issue for metal fabricators, and leads to significant downtime.  A Parker  Hannifin nitrogen generator, which separates nitrogen and oxygen from a compressed air supply, can often be the most cost effective way to supply this nitrogen.

 

Laser Cutting -- By far the largest use of nitrogen gas within the laser application sector is for CO2 laser cutting.  Nitrogen gas is used as an ‘assist gas’ to prevent oxidization or discoloration and to blow away the molten material from the cut edge.   It is also used in certain types of laser cutting machines as a ‘purge gas’ to ensure the laser beam guide path from the resonator (where the beam is generated) to the cutting head, is free of contamination that could otherwise affect the power or alter the shape of the beam.

 

Laser Sintering -- Laser sintering or rapid prototyping, uses a laser to form a solid 3D structure within a plastic powder material.  Complex shapes and patterns can be constructed and modeled with ease.  Nitrogen is used to blanket and prevent oxidization of the powder material while it melts and solidifies to shape under the heat generated by the laser beam.

 

Laser Ablation -- Nitrogen is employed to expel fumes and blanket delicate electronic circuits where a laser beam is used to erode pathways on micro-printed circuit boards.

 

Laser Eye Surgery --Nitrogen is employedas a beam purge and pneumatics gas on Eximer laser machines which are used in the corrective treatment of eyesight defects.

    Laser Beam Path Purge

    Contamination in the beam path of a laser is a major issue for metal fabricators, and leads to significant downtime. Costly service contracts are typically utilized by laser manufacturers to safeguard against these downtime issues. A Parker nitrogen generator, which separates nitrogen and oxygen from a compressed air supply, can often be the most cost effective way to supply this nitrogen.
