Pulsed Power for the Electra
Electra is a rep-rate Krypton Fluoride (KrF) laser that will be used to develop the technology required for an Inertial Fusion Energy (IFE) Power Plant. Electra will use the same type of architecture as the Nike 60 em amplifier [1], e.g. double-sided electron beam pumping of the laser gas, but it will run at 5 Hz and use technologies that can meet the IFE requirements for efficiency, durability...
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...
متن کاملAmplification of ultrashort pulses in krypton fluoride at 248 nm.
Ultrashort pulses were produced at 248 nm by using a transverse-discharge KrF* excimer laser as a high-energy amplifier system. Input pulses for the amplifier system were obtained by upconverting the output of a modelocked visible dye laser to the ultraviolet by using nonlinear crystals. Pulses of up to 20 mJ; in energy with 10-30-psec duration were obtained at 10 pulses/sec. The output pulse w...
متن کاملGeneration of 35.5-nm coherent radiation.
Tunable coherent radiation was produced at 35.5 nm by seventh-harmonic conversion of 248-nm radiation from a krypton fluoride excimer laser. The nonlinear interaction took place at the intersection of the laser focus and a pulsed, supersonic helium gas jet. Third- and fifth-harmonic generation produced coherent outputs at 83 and 50 nm in both helium and xenon gas jets.
متن کاملADVANCED 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...
