CO2 lasers

  JSC “Research Institute of Gas Discharge Devices “PLASMA”” manufactures a wide range of gas-discharge molecular lasers based on carbon dioxide.

CO2 lasers are really outstanding devices among gas-discharge lasers.

Maximum efficiency of conversion of electrical energy to laser radiation energy permits to achieve 20 kW of output power in CW operation and pulse energy up to 100 kJ.

CO2 lasers are referred to the class of molecular gas lasers emitting on vibrational transitions of CO2 molecules in the IR regions of spectrum at 9-10 um. As a rule, all lasers operate on a mixture of CO2:N2: He in different proportions with an addition of a small quantity of Xe.

Opportunities of CO2 lasers

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.

Application Sphere of CO2 lasers

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.

This also makes the laser not dangerous for eyes, because emission does not penetrate through the eye cornea and crystalline lens.

Of course, a directed beam of high power can damage the eye cornea, but to protect the eyes, it is enough to have common glass or plastic spectacles.

In order to achieve maximum effect in surgery, it is important to evaporate biotissue without the heating of the surrounding tissue. For this purpose peak power is necessary, i.e. pulse mode. Today superpulse mode is used in CO2 lasers, at which laser emission consists of a number of short, but 2 – 3 times more powerful, pulses in comparison with the average power of the laser with continuous operation.
