Carbon dioxide (CO2) lasers use the energy-state transitions between vibrational and rotational states of CO2 molecules to emit at long IR, about 10 µm, wavelengths. These lasers can maintain continuous and very high levels of power and are typically used in cutting, welding, etching, and marking applications.

A unique mathematical model to simulate the process of cutting natural stones in rectilinear (straight line) path, by carbon dioxide (CO2) laser, was implemented in a personal computer. The implemented model determined the shape and dimension of the kerf (cut slots or channels) using such variables...

...so a carbon dioxide (CO2) laser, with nominal output at a wavelength of 10.6 um, is well matched for this task. In contrast, many organics are transparent at the near infrared output wavelength (1.06 um) of industrial lasers based on Nd:YAG. Most organics also are strongly absorptive in the deep...

...inch thickness and for these depths a multi-kilowatt laser, such as the carbon dioxide type, must be used. We need to mention that although there are many laser types, the Nd:YAG and carbon dioxide lasers (CO2) are most common in production metal working. Carbon dioxide lasers utilize a combination...

...of the investigations two different laser sources were used. To verify feasibility, a carbon. dioxide laser system was selected. Further experiments were performed using a solid state laser. The CO2 laser used is a high power system emitting a medium output power of PL = 2.3 kW. This laser offers...

...leap to support job shops looking to expand their capabilities. How have the gas systems evolved to support these advanced capabilities?. It's About the Gas. Job shops have several choices in resonator technology, from excimer, YAG, and carbon dioxide (CO2) to diode, fiber, and disk. Each design has...

...of hydrofluoric acid (HF), silicon tetrafluoride (SiF4), carbonyl fluoride (COF2), and carbon dioxide (CO2) are produced by surface reactions.2 These impurities, if they reach the laser during initial filling after hookup, can poison the laser cavity. Gas suppliers or laser manufacturers may be held...

It is usually circular and specified by its diameter. Closed installation: Any location where lasers are used that will be closed to unprotected personnel during laser operation. CO2 laser: A widely used laser in which the primary lasing medium is carbon dioxide gas. The output wavelength is 10.6...

7001vr is a handheld CO2 monitor that calculates and displays air quality. Use the PDA-sized portable to gauge carbon dioxide concentrations both inside and outside your office building. It calculates the difference between the two and estimates the rate of atmospheric change. Anything under 15...
