Industrial solutions for the carbon dioxide (CO2) lasers - Monitoring and Testing - Air Monitoring and Testing
Carbon Dioxide (CO2) lasers are high power lasers, usually used for cutting of ferrous and non-ferrous metals. High-performance gas flow control is a key requirement for achieving high cutting performance with CO2 lasers. Gas flow control plays an important role for mixing key gases at a number of locations with a CO2 laser: Beam Generation: The gas mixture used as the emitting medium usually consists of CO2, He and N2. Most laser manufacturers specify a minimum required purity for the beam generation gas mixture, which is typically > 99.99%. A highly-accurate gas mixing control is therefore necessary, either for production of pre-mixed gas cylinders, or for in-situ mixing within the laser unit.

Product Overview:
Purging: A high purity gas, usually dry nitrogen, is used to purge the laser transmission tube, in order to avoid problems which may arise due to dust particles or humidity.
Assist Gas: Usually O2 or N2 is used as a cutting assist gas which helps to remove material from the cutting edge.
