title: Spatial quantum noise in singly resonant second-harmonic generation.
abstract: We study the spatial distribution of quantum noise in singly resonant second-harmonic generation. Calculations are performed below threshold for spatial modulational instability. For parameters for which the intracavity fields are modulationally stable the spatial spectrum shows maximum squeezing at k=0, whereas under conditions of modulational instability we find maximum squeezing at finite wave number |k|=k(c), where k(c) corresponds to the classical critical wave number.
