The importance of molecular complexes in gas discharge lasers has long been recognised, and indeed they are the essence in excimer lasers. For other discharge lasers operating with gas mixtures, for example metal vapour lasers, the role of molecular

The pressure dependence of the intensity for optical frequency breakdown of nitrogen and argon has been studied using single similar 20 ps, Nd3+ laser pulses at the fundamental and second harmonic frequencies. The gases were studied over a pressure r

A CW multi-line He-Cd+ laser is described which uses a geometry of alternating hollow cathode and annular anode elements. Operating parameters are measured systematically to optimise the efficiency of the laser and its spectral output. The laser emit

An analysis of the role of primary spherical aberration in governing the intensity distribution of a focused laser beam has been confirmed by recording the fluorescence caused by the passage through a dye solution of radiation from both an Nd3+ laser

The breakdown of gases by short (typically sub-nanosecond) laser pulses when the two dominant mechanisms governing the plasma growth are multiphoton and cascade ionization is treated theoretically. It is shown that two important pressure r?gimes resu
