【Abstract】 Ar optogalvanic spectrum was observed in wavelength regions of the laser dyes on hollow cathode discharge as well as the time, discharge current and laser power dependences of optogalvanic signals. After comparing the optogalvanic effect of Ar with that of Ne, the machanism of optogalvanic effect is discussed, a theoretical model is suggested and the laser power dependence of discharge current is obtained.更多还原
