An external control with a fast temporal response for a microbarrier discharge has been developed. It is experimentally found that the wall voltage of the microbarrier discharge is modulated by an external irradiation of YAG laser with a weak intensity. As the results, the breakdown of microbarrier discharges is induced and one dimensional array-type microbarrier discharge device can be controlled by the external optical irradiation of a pulsed laser. The technique of the optical control of microdischarge is helpful for further development of super precise display panel and for various applications of microscale measurements
