Knowledge

What is CO2 laser?

Work principle of CO2 laser

Carbon dioxide lasers are a molecular laser. The main substance is a carbon dioxide molecule. It can express a variety of energy states. This is dependent on its vibration and rotation. The mixed gas in carbon dioxide is a plasma (plasma) formed by the low pressure gas (usual 30-50) due to electron release. As the Law of the Maxwell Pozman distribution said, in plasma, molecules present a variety of excitement states. Some will present high energy (0010) which appears as asymmetric swing state. This molecule also lost energy when colliding with a hollow wall or naturally. By naturally emitting this high energy state to a symmetrical swing form (100) and an emitted photon may propagate to any direction (a beam of a wavelength of 10.6 μm). Occasionally, a kind of photon will be spread downward along the cavity of the optical axis and will be swayed in the resonating mirror.

In general, the working substance of the carbon dioxide laser is a mixture composed of carbon dioxide and helium nitrogen. Nitrogen as a cushioning gas and its molecules resonately transmit stimulation energy to the carbon dioxide molecule. Because the relaxation level is a bottleneck, the effect of helium is used as a ferrule to transfer energy to the helium atom.
