Some characteristics of efficient dye laser emission obtained by pumping at 248 nm with a high power KrF1 discharge laser

Characteristics of dye laser emission under high intensity uv pumping, at 248 nm wavelength have been investigated with peak pump powers of ～ 10 MW at a pulse duration of ～ 30 ns, provided by a multi-atmosphere KrF¹ discharge laser. Energy conversion efficiencies, spectral features and temporal behaviour of several dyes were parametrically studied. Significant pump intensity dependent conversion efficiency and pulse shape variations were observed for the most efficient uv dye, p-terphenyl.
