Carbon-dioxide laser - Wikipedia
The 9–12 μm wavelength of CO 2 lasers is useful because it falls into an important window for atmospheric transmission (up to 80% atmospheric transmission at this wavelength), and because many natural and synthetic materials have strong characteristic absorption in this range.
CO2 lasers are typically available in three wavelengths: 9.3 µm, 10.2 µm, and 10.6 µm. 10.6 µm • This wavelength works well for most common marking, engraving, and cutting applications.
CO_2 Lasers – carbon dioxide laser - RP Photonics
The CO 2 laser (carbon dioxide laser) is a molecular gas laser with emission in the long-wavelength infrared spectral region. It is based on a gas mixture as the gain medium, which contains carbon dioxide (CO 2), helium (He), nitrogen (N 2), and possibly some hydrogen (H 2), oxygen (O 2), water vapor and/or xenon (Xe). Such a laser is ...
Carbon Dioxide (CO2) Lasers Information - GlobalSpec
Wavelength. Compared to other lasers, CO 2 lasers are confined to a relatively small range of wavelengths occurring exclusively within the infrared (IR) spectrum. Carbon dioxide lasers almost always emit light within the 9.4 μm to 10.6 μm band, which corresponds to roughly 28.3 terahertz (THz) to 31.9 THz.
CO2 Lasers: Types, Uses, Features and Benefits - IQS Directory
Unlike other types of lasers, CO2 lasers operate within a narrow range of wavelengths, all of which fall within the infrared (IR) spectrum. Typically, these lasers emit light in the range of 9.4 μm to 10.6 μm.
Wavelength (9.3 µm, 10.2 µm, or 10.6 µm) • Wavelength refers to the wavelength of light produced by the laser. • Lasers emit monochromatic (single wavelength) light. 9.3 µm, 10.2 µm, and 10.6 µm wavelengths are most common for CO2 lasers. • If a material has higher absorption of a given wavelength, processing is faster and the
CO2 lasers - functionality and areas of application - Trotec Laser
The CO 2 laser emits in mid-infrared between ~9µm to ~11µm wavelength, the strongest emission line is often 10.6µm (more rarely at 9.3µm or 10.2µm). Together with Nd:YAG/fiber lasers, the CO 2 laser forms the backbone of industrial laser technology.
CO2 Laser Sources Types, differences and applications - EVlaser …
CO2 lasers typically emit at a wavelength of 10.6 μm, but there are dozens of other laser lines whose wavelength ranges between 9 and 11 μm (in particular at 9.6 μm). The glass CO2 laser source is the only source stimulated by the DC voltage. The design of glass laser tubes has remained pretty much the same since their introduction in the 1960s.
The wavelength of CO2 laser - El. En. Laser
It has been demonstrated that some lasers have a wavelength which makes them suitable for a wide range of applications. The CO2 laser in particular has a wavelength of 10.6 micrometres, which is in the far-infrared region. This length is absorbed …
Sam's Laser FAQ - Carbon Dioxide Lasers - Repair FAQ
Unlike the other lasers producing visible or short near-IR light, the output of a CO2 laser is medium-IR radiation at 10.6 um. At this wavelength, normal glass and plastics are opaque, and water completely absorbs the energy in the beam.
