ADVANCED PULSED POWER CONCEPT AND COMPONENT DEVELOPMENT FOR KrF LASER IFE*
The Electra advanced pulsed power development program has the goal of developing and demonstrating pulsed power technology that is applicable for KrF (krypton fluoride) Laser IFE (inertial fusion energy). The application presents efficiency, lifetime and cost challenges that mandate the use of advanced pulse compression topologies. In turn, these advanced topologies require the development of c...
متن کاملDevelopment of high-power laser coatings
Laser resistance and stress-free mirrors, windows, polarizers, and beam splitters up to 400 mm × 400 mm are required for the construction of the series SG facilities. In order to improve the coating quality, a program has been in place for the last ten years. For the small-aperture pick-off mirror, the laser-induced damage threshold (LIDT) is above 60 J/cm2 (1064 nm, 3 ns), and the reflected wa...
متن کاملDevelopment of a Multipurpose Water Reuse and Power Production System
In today’s world renewable energy is highly demanding because of increasing oil and fuelprices, desire and necessity to avert irreversible climate damage and also the unreliability of the non -renewablesources. In renewable energy, water is an important source. Previously water is used only for survivalof human being as much as food but no attentionhas been givenen to economical use and conserv...
متن کاملFast - Discharge - Initiated KrF Laser
Intense laser emission has been observed from the KrF molecule formed by a chemical reaction initiated by fast-discharge circuitry. With a gas mixture of He:Kr:NF, = 500:50:1 and a sample pressure of 700 Torr, an output energy of 0. 8 mj was measured from a 25-nsec laser pulse (FWHM). Spectral analysis of the laser emission indicated laser action at 248.5 and 249.5 nm.
متن کاملHigh Rep-Rate KrF Laser Development and Intense Pulse Interaction Experiments for IFE*
A high repetition-rate e-beam pumped Krypton fluoride (KrF) laser has been developed as a prototype of future IFE driver. A combination of power supply with high voltage magnetic switches and e-beam diode cooled by water and self heat-radiation is generating e-beam at 0.5 Hz. Laser oscillation at 1 Hz with output energy over 20 J is expected in near future. Intense short pulse (> 10 J, ~3 ps) h...
