By operating a Nd:YAG regenerative amplifier with an intracavity spatial aperture, it is found that spectral broadening and chirp sufficient for pulse compression are produced at intracavity intensities well below the self-focusing threshold. Stable, synchronous pulse compression of as much as a factor of 4 has been achieved, while a factor of 8 is possible.
