  Materials that exhibit ferroaxial order hold potential for novel multiferroic
applications. However, in pure ferroaxials, domains are not directly coupled to
stress or static electric field due to their symmetry, limiting the ability to
pole and switch between domains -- features required for real-world
applications. Here we propose a general approach to selectively condense and
switch between ferroaxial domains with light. We show that circularly polarized
light pulses on resonance with infrared-active phonons manifest
helicity-dependent control over ferroaxial domains. Nonlinear contributions to
the lattice polarizability play an essential role in this phenomenon. We
illustrate the feasibility of our approach using first-principle calculations
and dynamical simulations for the archetypal ferroaxial material
RbFe(MoO$_4$)$_2$. Our results are discussed in the context of future
pump-probe optical experiments, where polarization, carrier frequency, and
fluence threshold are explored.
