A CO2 laser marker is a tool that uses a focused beam of light to mark or engrave materials, such as wood, plastic, or metal. The laser is powered by a gas mixture that includes carbon dioxide, which allows for precise and accurate marking. CO2 laser markers are commonly used in a variety of industries, including manufacturing, labeling, and identification. They are known for their ability to make clean and permanent marks with minimal heat or impact on the material being marked.

• CO2, or carbon dioxide, is a naturally occurring gas that is essential for life on Earth. It is produced through the process of respiration by plants and animals, as well as through the burning of fossil fuels and other human activities.
• In recent years, CO2 levels in the atmosphere have been rising at an alarming rate due to increased human activity, such as the burning of fossil fuels for energy and transportation. This increase in CO2 has contributed to climate change and the greenhouse effect, causing global temperatures to rise.
• To better understand and track the levels of CO2 in the atmosphere, scientists use a measure called a CO2 marker. This is a tool that measures the concentration of CO2 in the air, allowing scientists to monitor changes in CO2 levels over time and understand the impact on the Earth’s climate.
