Which CO2 Laser Tube Is Best – DC or RF?

If you’re attempting to understand the differences between a DC and an RF excited CO2 laser tube – to help with making a purchase decision – then this content is a good destination to start.  One of the first decisions when buying a CO2 laser for cutting and/or engraving is the choice between a Direct Current or Radio Occurrence excited laser tube.

The release creates a photonic co2 laser tube beam that bounces back and forth until a certain level of energy  is accomplished, then the photonic (light) beam exits the laser at one end.  This infrared beam is unseen but powerful as soon as focused may be used to trim or engrave various materials. Incidentally the word LASER is in fact an acronym that identifies this process:  Light Amplification by Stimulated Emission of Rays.

An alternative solution way to transfer energy in to the gas is via. radio occurrence (RF).  co2 laser tube technology is commonly referred to as “metallic” pipes. RF excitation produces a pulsed laser with an exceptionally quick repeatability. Unlike the parallel release in a DC fired up tube, the RF laser discharges perpendicular to the resonator.

Head to Head Comparison

When deciding which laser is most effective for your application, understanding the professionals and cons of each laser is critical. Below we break down the major factors when contemplating these different systems.

  • Cost: DC lasers manufactured from glass are roughly 10% of the price of RF lasers. This cost benefit is because a lesser technology and making cost. Border: DC
  • Trimming Performance: Both lasers maintain very high quality cuts. The border quality is virtually identical. However, because RF lasers are pulsed, some materials may show a slightly rough edge. This is apparent in acrylics. With that being said, this difference in quality is hardly visible to most users.
  • Engraving Performance: RF lasers create a smaller place size from the output home window of the laser. Small the spot size, the finer the engraving information. For high perfection engraving, this smaller spot size makes a difference. There are numerous applications where this advantage in quality won’t make itself clear. Advantage: RF
  • Endurance: Experience shows that RF lasers last 4-5 times much longer than DC lasers. This durability can help offset the initial higher cost of the RF laser. The gases inside RF lasers can sometimes be refilled but this technique can be more expensive than the replacement unit cost of new DC laser.

Comparing Laser Electricity RF vs. DC

If you were to compare a 100W RF to a 100W DC tube then assuming everything are identical – the energy is the same.  Electric power is electric power; However, RF electric power focuses that same energy into a more dense, smaller area size. The quality and stability of that beam is better as well. For detailed etching RF can offer that gain. However, with lowering you can afford to ‘buy’ a lot more cutting power compared to the expense of RF.  So, identifying what you would be making use of your co2 laser tube for can help you make that decision.
