Advanced techniques of high-efficiency pulse compression for KrF lasers

High - Intensity Short - Pulse Lasers

High Resolution Low Power Radar Pulse Compression Techniques

Pulse Compression Techniques are used in Radar systems to avail the benefits of large range detection capability of long duration pulse and high range resolution capability of short duration pulse with low power consumption. In this paper, details of these techniques are given which achieves high range resolution and low peak sidelobe levels under various noise conditions, Doppler shift and mul...

Advantages of KrF Lasers for Inertial Confinement Fusion Energy

Advanced concepts for direct drive inertial confinement fusion (ICF) have emerged that may lead to sufficient gain for the energy application (g>140) at laser driver energies as low as 1 megajoule. For example, recent “shock ignition” designs compress low aspect ratio pellets then apply a final high intensity spike pulse (10 16 W/cm 2 ) to ignite the fuel via a converging shock wave. These anal...

High 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...
