Abstract: The method for stabilizing the output power of the gas discharge laser using an auxiliary electrode to control the discharge current comprises following steps, (a) dividing a laser beam (2) with a photo divider (1); (b) detecting the divided laser beam or a part of laser beam reflected by a full reflection mirror (3) with a photo detector (4); (c) converting the fluctuation of the laser output to the variation of impedance of the discharge tube; and (d) controlling the voltage providing to the auxiliary electrode with a feedback controller (5).

Abstract: PURPOSE: An apparatus and a method for inspecting quantum efficiency homogeneity of a solar cell are provided to simplify an inspection by selecting the number of pixels and a pattern. CONSTITUTION: A light emitting device emits light. An image device changes a light path according to the individual control of a plurality of pixels. An image device controller(300) individually controls the plurality of pixels. Light passing through or reflected by the image device is radiated to a solar cell(400). A calculation controller(900) calculates quantum efficiency of the solar cell based on an optical current generated from the solar cell.
