Optimization of dye spectral range with a pulsed dye laser pumped by an XeCl excimer laser is described. The dyes were tested in an eight-cell oscillator–amplifier dye laser which is also described. Several solvents and mixtures of dyes were used for continuous coverage over 335–910-nm range. An additive to the solvent prevented deposits on the inside of the dye cells. The emitted wavelength can be extended to the UV by second harmonic generation. An achromatic device for separating the UV from the fundamental wavelength without beam displacement is described.
