The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser (pulse duration less than 2 mus) with carbon and activated carbon cloth was investigated. The investigations have shown that carbon cloth had been physically modified by the TEA CO2 laser. The type of modification strongly depends on laser working regime, such as energy density of the laser beam, etc. The morphology transformations induced by interaction with TEA CO2 laser beams resulted in different specific surface area of activated carbon cloth. Also, laser interaction induced minor changes in crystallographic structure parameters.
