Barrier-discharge-excited coaxial excilamps with the enhanced pulse energy
- Institute of High Current Electronics, Siberian Branch, Russian Academy of Sciences, Tomsk (Russian Federation)
The parameters of sealed off barrier excilamps are studied at high excitation powers. The total output pulse energy up to 25 mJ is achieved (the emitting area of a KrCl excilamp was up to 1500 cm{sup 2}, the output power was above 100 kW, and the efficiency achieved 10%). It is shown that a volume discharge was formed in the coaxial excilamp when the energy supplied to the working mixture was increased and the pulse repetition rate was increased up to 50 Hz. The peak radiation intensity on the excilamp surface achieved {approx}100 W cm{sup -2}. The optimal excitation energy of a barrier excilamp was found to be 0.1-0.2 mJ cm{sup -3}. The excilamp efficiency rapidly decreases with further increasing the input energy. (laser applications and other topics in quantum electronics)
