自走放電型ナノ秒Xeパルス白色光源の空間過渡発光特性

抄録

We describe the spatial and spectroscopic transient emission behavior of a free-running, nanosecondpulsed, Xe discharge lamp.The standard dc-operated Xe lamp, which is commercially available, was employed as the primary light source with modified circuitry to realize pulsed operation. In order to measure the spatial characteristics of pulsed emission, we used a shadow-graph universal projector and/or an apparatus for single-photon correlation measurements. We have found that emission near the cathode electrode in the lamp give the narrowest pulse width of 3.2ns at a wavelength of 250nm.
