Operation of pulsed Nd:YAG laser simultaneously at 1.052, 1.061, 1.064, and 1.074 μm is reported. The suppression of the weaker lines by the strongest line (1.064 μm) is avoided by using a cavity scheme which disperses the frequency components transversely in the crystal. The frequency doubling of this radiation in KDP provides several new lines.
