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...

متن کاملNear-field nonuniformities in angularly multiplexed KrF fusion lasers with induced spatial incoherence.
Induced spatial incoherence (ISI) has been proposed for KrF laser drivers to achieve the high degree of spatial beam uniformity required for direct-drive inertial confinement fusion. Although ISI provides ultrasmooth illumination at the far field of the laser, where the target is located, it can still allow the beams in the quasi-near field to develop a time-averaged spatial structure. This spe...
متن کاملEnhance refractive index modification of fused silica by multiwavelength excitation process using F2 and KrF excimer lasers
A multiwavelength excitation process using F2 and KrF excimer lasers for the high-efficiency and high-speed refractive index modification of fused silica is demonstrated. This process is essentially superior to conventional single-wavelength F2 laser processing. The former process achieves twice the diffraction efficiency of the latter process at the same number of total photons supplied to the...
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.
