Perspectives

PLASMA PHYSICS:
Laser-Generated Jets and Megagauss Magnetic Fields

John Stamper*

An intense laser pulse interacting with plasma (a gas of ionized matter) can generate enormous magnetic fields. In his Perspective, Stamper discusses work recently published in Physical Review Letters in which fields in the range of millions of gauss have been observed. The findings are important both for fundamental plasma physics and for evaluating the feasibility of novel laser fusion strategies.

The author is retired from the Naval Research Laboratory, Washington, DC.
