A new method was proposed for the production of a localized supercritical electroconvection (EC) pulses. An experiment was performed in which a weak continuous-wave absorbed laser beam with a diameter comparable to the pattern wavelength. Systematic measurements of the sample-voltage dependence of the pulse amplitude, spatial extent, and frequency show a saturation or decrease when the control parameter approaches ∼0.3. It is observed that the advection creates a negative feedback between the pulse size and the efficiency of heat transport.
