Experimental diagram for photomechanical mirror measurements.
Continuous or pulsed excitation beams were focused on the sample surface. A continuous laser was arranged almost collinear to the excitation beam to probe the deformation of the liquid surface. The intensity variation of the probe beam center after reflection was detected by a pinhole-laser line filter-photomultiplier (PMT) assembly in the far-field. A digital oscilloscope triggered by the photodiode (PD) recorded the data at a repetition frequency of 
for the pulsed experiments and 
for the continuous. The apparatus was set up in separated actively damped optical tables to eliminate mechanical vibration on the liquid surface. The temperature of the samples was 
. A detailed description of the experiment is presented in the Methods section.
