PURPOSE:To make a starting pole needless and stabilize flash light at high brightness by lowerng impedance between the anode and the cathode inside a lamp proper while generating plasma discharge between both poles along the orbit of laser light. CONSTITUTION:When impressing the fixed voltage between the anode 11 and the cathode 12 inside a lamp proper 10 while discharging laser light L of high energy from a laser discharge port 13a, said laser light L instantaneously passes through the lamp proper 10 while reaching again the outer side of the lamp proper 10 from a small hole 11a through the small hole 12a. That is to say, when laser light L passes from the anode 11 to the cathode 12, an inclination is generated in potential distribution in the space between both poles and therewith impedance between both poles lowers to start plasma discharge between both poles while generating flash light L. Thereby, the starting pole between needles while stabilizing flash light at high brightness. |
