Rapid changes of the refractive index in the active medium of a pulsed, excimer laser pumped dye laser amplifier were investigated with an optical heterodyne technique. Time-dependent shifts in the phase of optical light waves could be observed which for Coumarin 102, 153 and 307 dyes at wavelengths of 488 and 550 nm depend predominantly on the thermal properties, in particular, on the expansitivity of the dye solutions. A fast Electro-Optic Modulator (EOM) using LiTaO3 crystals has been designed for compensating these phase perturbations. With appropriately shaped voltage pulses applied to the EOM the resulting changes in the instantaneous frequency of the pulsed laser output could be lowered by a factor of 4 with respect to the values measured in the uncompensated light.
