International Workshop on Laser Beam and Optics Characterization (3ª. 1996. Quebec)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.Beam quality of TEA CO_2 laser pulses: Influence of the gas mixture and of intracavity aperturesbook parthttp://dx.doi.org/10.1117/12.259902http://proceedings.spiedigitallibrary.org/metadata only access535EngineeringElectrical and ElectronicInstruments and InstrumentationOpticsÓptica (Física)2209.19 Óptica Física
