Summary of the status of lasers for inertial confinement fusion

PDF Version Also Available for Download.

Description

Laser systems designed for plasma research are operating in many laboratories throughout the world. The laser performance itself has become reasonably consistant from laboratory to laboratory and the focusing properties of the laser beams are understood. The plasma physics data, obtained with these systems, also appears to be reasonably self-consistant and is of great interest for inertial fusion applications. These lasers are commonly providing output powers of 0.5 > 2 TW, and power densities on target of 10/sup 13/-10-/sup 16/ W/cm/sup 2/, pulse durations on the order of 100 psec to 3 nsec, wavelengths between 0.5 ..mu.. and 10 ..mu.., ... continued below

Description

Laser systems designed for plasma research are operating in many laboratories throughout the world. The laser performance itself has become reasonably consistant from laboratory to laboratory and the focusing properties of the laser beams are understood. The plasma physics data, obtained with these systems, also appears to be reasonably self-consistant and is of great interest for inertial fusion applications. These lasers are commonly providing output powers of 0.5 > 2 TW, and power densities on target of 10/sup 13/-10-/sup 16/ W/cm/sup 2/, pulse durations on the order of 100 psec to 3 nsec, wavelengths between 0.5 ..mu.. and 10 ..mu.., and focal spot sizes of 100 ..mu.. or larger where focal spot edge effects are becoming less dominant. In addition, spurious target responses due to such behavior as pre-pulses, self-focusing, or imprecise focal spot measurement are being observed less often. The technical problems of large multi-beam systems, performing at the 10 TW level, have been overcome and these systems (e.g. the Shiva and Helios lasers) are providing high density compression data with ablative targets. The next step in laser design, the 100 to 300 kJ systems, are under construction and 1 MJ lasers are being contemplated.
