A Quick and Dirty Introduction to RD and DC in the World of Lasers

Which laser is the best? Most people would say “Well, all of them, really.” The team at Boss Laser would largely agree. Regardless, there are a few subtle little things that make some lasers amazing and some lasers close to amazing.

Many potential buyers hear all sorts of things about laser types, but it often comes down to one of two main types to choose from. This is because they vary in some odd ways, which will be discussed, but they are both consumer-friendly and affordable. These two types are the Direct Current lasers and the Radio frequency lasers.

Direct Currents and Glass

Direct current lasers are often synonymous with glass tube lasers because most Direct Current lasers are made of glass. There can be a distinction, as some providers have started offering metal-built Direct Currents.

The DC 40W laser tube is obviously named for how it works, which often makes all the difference. A direct Current laser actually charges the laser internally within the glass. So, the combination of natural components (hydrogen, nitrogen, etc) will funnel within the glass and “create” an energy funnel of sorts. The funnel is sustained with enough intensity to discharge as a laser. The entire design is built on the creation of a laser internally, as it is discharged as a photonic beam.

Radio Frequency and Metal

The discharge of a Radio Frequency system is not dissimilar. It actually charges internally and is relinquished as a quick pulse. The difference is that RF tubes are almost always made of metal. They also allow for a quick recharge due to the creation of the initial pulse. The laser will also discharge in a perpendicular direction, unlike the DC tube which discharges parallel to the point of the laser. It also goes without saying that RF tubes are initiated on a radio frequency that can actually adjust the laser concentration.

Which one works better? This is a constant and somewhat futile debate. Glass is more of a traditional form, while the metal tubes and the radio frequency options are more high-technology. These are some of the performance differences of these two accessible marketplace laser types.
