The full spectrum of vibrational-rotational transitions of a CO2 molecule provides a possibility of discrete and continuous tuning of frequency (wavelength) which makes a CO2 laser an indispensable tool for the use in photochemistry， in environmental monitoring systems and IR detection systems. The range of stimulated emission is considerably increased due to the use of the so called “hot” sequential transitions. A CO2 laser features unique spatial characteristics: high directivity and homogeneity. The existing technological production support of industrial prototypes of CO2 lasers ensures their long (more than 10 000 hours) stable sealed-off off-line operation. This results in a significant improvement of technical characteristics of devices and systems using CO2 lasers， such as engraving and decorating machines， printing equipment and surgical apparatus. The excellent quality of the beam makes sealed-off CO2 lasers of relatively low power (50-100 W) extremely effective for the use in mechanical processing of metal and non-metal materials (drilling， milling， scribing) and in the welding of different materials.
Processing and Engraving of Materials using CO2 lasers
CO2 lasers are widely applied in laser engravers. With their help a wide range of materials is being processed: wood， cardboard， electric-grade cardboard， paronite， rubber， leather and synthetic leather， fabric， organic glass， acryl， polystyrol， ABC plastic， polymer resin， ceramic tile and ovenware， glass， natural and synthetic stone (granite， marble， touchstone)， sewing fittings， anodized aluminium and colored metals.
The Usage of CO2 Lasers in Medicine
CO2 lasers are widely used in medicine， particularly in surgery. High level of absorption in water and organic compounds (typical penetration depth is 0.1 mm) makes CO2 lasers suitable for a wide range of surgical intervention， as well as for gynecology， otolaryngology， general surgery， dermatology， plastic and cosmetic surgery. The surface laser effect allows cutting biotissue without serious burns.
