Along with the development of modern industry and the progress of science and technology, the application of light is more frequent. Carbon Dioxide Lasers are the lights that are the most relevant to our lives.
From advertising to clothing, marking processing to automobile manufacturing, scientific research and medical to military development. Plenty of fields are inseparable from CO2 lasers.
In order to meet the market demand for high-power CO2 lasers, the 300W CO2 Laser Tube with beam-combination techniques was developed.

There is a variety of laser beam combining approaches to get high laser power, yet, the polarised beam combination is one of the most efficient techniques, with a beam combining efficiency close to 100%".
The core benefits of Beam Combined 300W CO2 Laser Tubes that compare to others are the extremely stable output power and high beam quality
