Abstract

This work reports the role some additives have in pre-ionizing a N2 TE UV laser (337.1 nm). The modifications in both stimulated radiation characteristics and excitation-pulse period prove the different ionizing power of each element. The laser operating without a pre-ionizing wire device and with N2 plus different additives was able to generate pulses with a temporal width of the same order than those obtained when it was operating with N2 and a pre-ionizing wire device. Also, a relation between ionization efficiency and interelectrode distance has been established allowing the prediction of conditions for optimum laser-pulse width generation.
