he laser beam is a source of radiation with concentrated energy. The characteristics of the laser beam (spot energy, focal spot diameter, spot temperature) are aspects theoretically researched in this paper. The intensity of the laser beam transmitted to the surface of the part has a Gaussian shape. A CO2 laser was used in the processing of parts from a HARDOX400 steel sheet with a thickness g = 8mm. The values of the cutting parameters were established by sample tests. An experimental design with 27 observations was analyzed. The width of the cutting slot at the straight profile was measured. Physical quantities derived from the cutting parameters and working parameters used were calculated. Spot energy, cost and interaction time were determined and evaluated using the mathematical model given by GRAPH. The research findings show that the best values of the factors studied converge to average values in minimizing Kerf.

ABSTRACT Objective To describe the results of treatment with CO2 laser for Bartholin gland cysts. Methods Thirty-one women with Bartholin gland cysts were treated with CO2laser at an outpatient´s setting. Skin incision was performed with focused laser beam, the capsule was opened to drain mucoid content, followed by internal vaporization of impaired capsule. Results There were no complications. Five patients had recurrence of the cyst and were submitted to a second and successful session. Conclusion CO2 laser surgery was effective to treat Bartholin gland cysts with minimal or no complications, and can be performed at an outpatient´s setting.
