We have investigated the preionization characteristics of x ray for a transversely excited, multiatmospheric pressure CO2 laser amplifier with an active volume as large as 225 cm3. The x-ray dose required for uniform avalanche discharge is measured as a function of pressure up to 10 atm. The dependence of the input energy density of the main discharge on the x-ray dose is also investigated.

    It is shown that a solid-state laser with unpumped sections of action medium which act as a saturable absorber, may operate in a stable, single-mode cw lasing regime. The establishment of lasing in a particular mode under steady-state conditions depends on the initial conditions of transient...

    Abstract. In this paper, we report on the realization of a 20-fs, 20-mJ laser chain operating at a repetition rate of one kilohertz. We emphasise the control on the pulse temporal and spatial profile, and its amplification at high average powers. This 1-kHz, terawatt laser is well suited for...
