Glass Tube  & Metal RF Tube

1. CO2 lasers are divided into glass tube type that oscillates with high-pressure discharge and metal tube type that oscillates with RF method.

2. Glass tubes have an absolute advantage in price, and RF metal tubes are superior in quality.

3. RF laser tubes are mainly produced in the United States and have been exclusively produced for a long time under patent protection, so there has been technological development, but the high price will be disadvantageous in the market because the period of protection from competition is long. In addition, price competition is disadvantageous compared to glass tubes due to increased transportation costs and taxes when moving to another country.

4. Glass tube type is mainly produced by several Chinese manufacturers and has secured the global market, and it is mainstream in the market with its low processing quality and very low price as an advantage.

In galvo type laser marking machines, RF type laser tubes will be the majority, and in x-y table type laser cutting machines, glass tubes will be mainly used.
