Abstract
This study experimentally demonstrates deterministic switching between square and squeezed hexagonal patterns by pump beam detuning and investigates its suitability as a control method. This paper also present an analysis of the effect of pump detuning on fundamental unstable modes under one transverse dimension and discusses its relevance for the control of two-dimensional patterns. Experimental results are compared to predictions obtained by means of a linear stability analysis.
