The external optical control of microbarrier discharges and its modulation of surface charges

研制了一种具有快速时间响应的微势垒放电外控装置。实验发现，微势垒放电的壁面电压受弱激光的外照射调制。结果表明，脉冲激光的外光照射可以诱导微势垒放电击穿，实现对一维阵列式微势垒放电装置的控制。微放电的光学控制技术有助于超精密显示面板的进一步发展和微尺度测量的各种应用

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
