Abstract

The aim of this work is to demonstrate numerically an optimal enhancement of nanoscale opto-hydrodynamic deformation of an air-water interface that involves an interaction between the size of the fluid medium and geometry of the continuous wave laser beam for a fixed radiation pressure force. We find a critical value of beam radii (ω_c) which produces the maximum deformation with a rapid onset time (t_on∼O(10⁻⁸) s) and high saturation time (t_sat∼O(10⁻²) s). Additionally, we show how the beam radius and water depth regulate an early onset and saturation time which depends linearly on the water depth once the optimal condition is achieved. Interestingly, we also show the stable and dynamic zones for deformation at the air-water interface. It is possible to validate our numerical results by using a variety of experimentally derived parameters, and these findings affect the characterization of complex fluids at the nanoscale.
