F. Caiazzo et.al investigated CO2 laser cutting process of three polymers that were polyethylene (PE), polypropylene (PP), polycarbonate (PC) in three different thickness ranging from 2 to 10 mm. The measurement of roughness taken on cut edges and faces was much better in the PP than that of PE. Polypropylene (PP) is a thermoplastic commonly referred to as a polyolefin. Commercially available products based on polypropylene include Formex ™ and Statex ™. Polypropylene can be processed with a 9.3 or 10.6 micron CO 2 laser without an appreciable difference in process quality. CO2 lasers have been used since the 1980s. Initially they were used for cancer and some other types of surgery, but then were found useful for facial resurfacing, which is a procedure where the outer layer of skin (the outer epidermis) and some of the inner layers of skin below it (the papillary dermis) were removed.

It is one of the earliest gas lasers to be Laser frakcyjny ablacyjny powoduje ściśle kontrolowany, fototermiczny uraz skóry.

Światło lasera ablacyjnego CO2 wnika w skórę i jest absorbowane przez zawartą w niej wodę. Se hela listan på de.wikipedia.org Laser Components Gas lasers consist of a gas filled tube placed in the laser cavity. A voltage (the external pump source) is applied to the tube to excite the atoms in the gas to a population inversion. The light emitted from this type of laser is normally continuous wave (CW).

While all CO2 lasers work on the same principles, a large part of the versatility of such lasers stems from the existence of several distinct designs, which vary in how they use the working gas and how they remove waste heat (see Fig. 2). The simplest design is the sealed-tube CO2 laser, which has a glass tube filled with the CO2-N2-He mixture. CO 2 lasers typically emit at a wavelength of 10.6 μm, but there are dozens of other laser lines in the region of 9–11 μm (particularly at 9.6 μm). This is because two different vibrational states of the CO 2 molecules can be used as the lower level, and for each vibrational state, there is a substantial number of rotational states, leading to many sub-levels.

It will not discuss the DC Power Supply requirements for flowing glass-tube lasers, or other more exotic CO 2 lasers. Typically, an RF-Sealed CO 2 laser will receive its power from a DC Power Supply and distribute the power internally to electronic circuitry.
