Large-bandwidth laser light pulses with pure frequency fluctuations have been generated. Chaotic-light pulses from a cavityless dye laser are temporally smoothed by passing them through strongly saturated amplifiers. Since the amplification process does not change the phase of the amplified light, the output radiation has the well-defined phase fluctuations of chaotic light, yet essentially no amplitude fluctuations.
