A modulated laser beam was used to generate capillary waves in a strongly absorbing liquid. The amplitude of the wave can be enhanced by placing the liquid into a resonant cylindrical container. At the proper modulation frequencies well pronounced resonances and standing waves were observed. The surface tension and viscosity of the liquid were measured.
