High-power-density electron-beam-sustained laser
Abstract
A high optical power-density excimer laser pumped by an electron-beam-sustained discharge has been developed. The electron-beam generator comprised a 200-kV pulse transformer-driven power supply and an electrostatically focused electron-beam diode. The careful design and optimization of this generator has allowed very reliable, reproducible operation of the complete laser system with a high enhancement ratio of 4.8. An average output power density of 0.63 MW cm-2 in a 250-ns (FWHM) pulse has been obtained from an e-beam-sustained discharge XeCl* laser with an extraction efficiency of 1.5%.
