RT Book, Section T1 Beam quality of TEA CO_2 laser pulses: Influence of the gas mixture and of intracavity apertures A1 Serna Galán, Julio A1 Martínez, C. A1 Martínez Herrero, María Rosario A1 Encinas Sanz, Fernando A1 Mejías Arias, Pedro Miguel AB We investigate from both a theoretical and an experimental point of view the dependence of the spatial parameters (integrated along the pulse length) of TEA CO_2 laser pulses on the presence of nitrogen in the gas mixture and also on the size of an intracavity diaphragm used to attenuate higher-order modes.
