We characterize and compress sub-nJ visible white-light continuum pulses generated by self-phase modulation in YAG. The spectral phase is retrieved by spectrally resolving the transient reflectivity from an optically-excited transition metal oxide. This measured phase is compensated by applying the appropriate distortion to a deformable mirror. By comparing the response of two different materials we show that the white-light pulses can be compressed to approximately 10 fs duration.
